The way that Hank Green and John Green are the back bone of the American public school system is UNREAL. Thank you, from the bottom of my heart. The impact you and your brother have made on the world is unreal.
Its nearly 1am on the day of my A+P 2 final... It's a 4-year-old video and still reviewed everything I needed to review for this concept... I'm a college student. Crash Course has always been a blessing for finals!!!!
You Know,I never find what he's saying in my textbook....but I still watch it anyway, because it's THAT GOOD I'm a 3rd year medical student,and still watch his videos because Everytime I do,I learn something new....he... along ninja science nerd....made me feel that I actually understand medicine somehow.... Good luck with your exams by the way 👍👍
It's not exactly temporary pain. Being a parent offers a lot of wear-and-tear on the body, especially when the child is in infancy. There's a lot of isometric-like exercise going on with constantly lifting and carrying someone that goes from ~5-9lbs to ~12-16lbs in just six months.
This youtube channel is amazing. it teaches children on youtube (which is where ALL kids are) about science and space etc. which is the real and good interesting stuff in life!
Turkey. Formally secular but going more and more religious conservative by the leadership. Im the last generation that finished highschool with reproduction lessons in humans in biology.
what do you mean you don't know me hank?! We've shared all these great times together! Like, remember when I watched all your videos? Hell that was pretty sweet now wasn't it. Don't you say you don't know me, it hurts.
+Emily Ericson I'm not shaming them, I'm shaming us for telling them it's ok to murder another human being just because that human being can't speak for his or herself. I feel anger, yes, but I don't hate anyone. A person's a person, no matter how small
+spindash64 We have never been told that it's okay. Women are mocked, shamed, and humiliated for simply not being at a point in their life where they are able to give birth to a baby. And by that logic, the millions of eggs inside my body right now are already people. A zygote is a zygote, not a person. Of course it's not an easy decision, but it's a decision that women should have the right to make.
+Nathan Pattison I'm sorry, but would you, as a man, be willing to put your life on hold for nine months for a child that you don't even want? To experience all of the horrible symptoms told about in the above video, to have to switch your entire life around? No. You wouldn't. What you have to say about what a woman does with her body does not matter, because you are not a woman. Just like you can't force a person to donate blood or organs against their will, you most certainly can't force a woman to go through this life altering experience because you believe a fertilized egg is a person.
@@-._.-KRiS-._.- They will still need certificate and do you think online learning is good enough. It would be if we all follow some good lecturers but when my lect try to make a vid LOL
I think it would be cool to have a crash course "What to expect" series. Lots of pregnancy sites have week by week calendars where they tell you what's up with baby. But Crash Course is so fun, I think it would be cool to see what they had to say about the 40 weeks of Pregnancy!
Girl I got it bad too, so I just watch as many scary delivery videos as possible & pay close attention to how evil the little things can potentially be at 3 & that helps me remember to wait till I have a degree before becoming a mother.
Gremistao Loco actually America has a slower repopulation rate than many other countries. Not sure where you got the idea from that we pop out babies on a regular basis but that’s really not how it is here.
Im happy,finally hearing a man to say:i really don't know how emotionally ladies bare someone,a whole new person growing in them. Yup,happy to hear someone respecting women.. With all respect to hank green for the sake of the respect he gave females with this very sentence.
It sounds like the fetus and the mother are having a pleasant biochemical conversation but consider this: the fetus can make a special kind of hemoglobin that has a higher affinity for oxygen than adult hemoglobin, which means that the fetus is pretty much wrenching oxygen away from the mother's hemoglobin. Still, the reason it evolved is because it works. Go biology!
The reproductive episodes have been hilarious, and of course informative :) Thanks for all your great videos, you have definitely helped me out a lot in my anatomy class! Final is tomorrow!
+kAshley92 I made someone laugh? Good, it means that my job here is done :P Also... I'm watching the original Shia video over and over again, where this clapping was taken from >.> :D
Thank you so much. Your human reproduction videos are excellent. I am glad you don't feel awkward talking about it because your videos really helped me to understand it.
Or, in Gaius Julius Caesar's case: "It involves a system of hormonal signals that, as sophisticated as they are, get interpreted by the very earliest human cells into two simple instructions: Divide, and Conquer."
+Robert Faber I thought you were headed toward Caesarean Section. It would be interesting to do another episode on all the things that can go wrong during this process.
i like how Thought Cafe did the illustrations. . . . They described it well enough and still kept it tasteful and entertaining... less is sometimes more
Thank you so much Crash Course! The way you explain things help me understand what the textbook is trying to explain. I have enjoyed learning A&P very much. Sometimes this course is down right tough, confusing, and hard to understand. Thank you for helping me make my light build came on! Those realization moments have happened many times Crash Course. I watch the videos after I have read the textbook because the host talks extremely quick and uses big words that are going to be used to explain steps in physiological processes. I guess that's why they called A&P. My thanks and best wishes go out to you.
I was introduced to your videos last semester in A&P1 and have watched you since! But this semester I was introduced to your history lessons AND I saw you in some art assignment videos! You've changed a lot in the years! Good for you, can't wait to see what you teach next ;)
These videos have been very helpful for me! However, maybe you can add to it by doing something about preventative birth control and contraception? Maybe about the different options available and how to prevent unwanted pregnancies as well as std prevention and how it works? I think that would really complete the sex education you have going on here.
Next week i have an oral exam on gynecology and obstetrics, and i need this info, its not like i dont know this, but when i see these vids i can memorize the facts a lot better and longer so... . Thank you for making the material so vivid and easy :)
Please don't induce your patients unnecessarily, especially if it's just because you want to deliver the baby a week early because you're going on vacation the week it's supposed to be born. That is all I ask of a future obstetrician.
Pregnancy is fun in the 3rd trimester. Getting past the 1st trimester is the most difficult. Just know that when people say 'contractions', that means that you will receive a pain exactly like your period cramps, only more intense.
I watched ur videos while preparing for my medical college admission test and now when I finally got admission (thank God) I’m still watching ur videos. ✌🏻😍
these videos have been sooo helpful because i have a science test on this subject and i didn’t know how to revise and then i found this and it was sooo helpful thank you
You are Gods! Seriously your channel thought me more than 10 encyclopedias worth of information! And you deliver the most important stuff if the subjects of the videos so than anyone can understand. No matter of they're a nerd or a regular! Thanks for keeping learning fun and awesome for me and everybody else! And, as always, DFTBA!
And I think that this channel is waaaaay more underrated than it should be! I mean you guys deserve to be shown to EVERY school there is and yet you have only what, 7mil?! I'm so grateful that I found this channel and that I was able to share it to more than 100 people. Keep doing your best!
Sorry to call you out, CrashCourse, and I know this from personal experience helping my lovely wife through delivery, the baby doesn't come out smoothly with an adorable "ShooooooOOOOOOP!" sound, though I very much wish it had. Also, I feel for that animated new mommy. That animated baby's head was MASSIVE!
My baby literally slipped out after the nurse told me to do two practice pushes. On the 2nd push, my baby's head started crowning. While they tried to get my OB in the room for delivery, Baby just slipped right out even though I was trying to keep her from coming out because they told me they weren't allowed to deliver w/o a doctor present.
Loving the episode! Not to be a pain in the ass, some things are wrong: the two cell stage is reached approximately 30 hours after fetilization. four-cell stage at 40 hours, and 12 to 16-cell stage is reached after 3 days and it is this 16-cell stage that is called morula. Besides this, good job guys!
Hi there, hopefully someone can clear this up. From my understanding, hCG is an endocrine process (meaning it travels through the blood stream) this is also how pregnancy tests work, as hCG is filtered through the blood it also goes through the kidney for excretion in the urine, thus, pee on the stick, the stick recognizes hCG and indicates pregnancy. Does it talk to the corpus luteum through endocrine or is it more of a paracrine automation? Thanks
RoScFan Actually in a strictly environmental safeguarding sense, 1 developed country human is SO MUCH WORSE than like 20+ something humans in a 3rd world country that the 3rd world can make as many babies as it wants, I don't really care. The sad reality is that most of them won't live long enough to impact the environment meaningfully. They don't own cars or consume tons of cheap plastic products every year. Most of the pollution they produce is in the CO2 they exhale and the organic waste they shit, and both of those thing are recycled into useful stuff by nature. They DO consume a lot of food, but all the develop countries together waste like 5 times as much as what the 3rd world eats. Having a baby in the developed world is really bad. It obligates you to have a car, because otherwise you don't have the time to make enough money to support everyone AND take care of the kid(s), The kid itself will "need" a bunch of toys, diapers, clothing, a room of his or her own, and ultimately he or she is likely to grow up into a ruthless business man that runs a profitable industry, but further pollutes the world. By 3rd world standards, we live like kings, and consume much more than what we actually need.
@@liwendiamond9223 Having a baby in the developed world doesn't have to be as problematic as you are claiming it to be. Use glassware to store food instead of plastics. Use the city bus. Stay home to raise the child on one income because it's doable if you budget properly, plus, it's 2019 and there are remote online jobs and/or freelancing jobs the stay-at-home parent can do to add income to the household. I'd imagine remote online jobs and freelancing existed in 2016 when you made your post. Use empty toilet paper rolls, wooden spoons, Christmas tinsel, everyday objects, _your_ old stuffed animal from childhood, as toys. Buy used toys or receive hand-me-downs. Use the public library for books, music, movies, iPads, laptops, free early development classes, etc. Use cloth diapers. Make your own laundry/dish soap. Have a safe, flat, hard surface the baby can sleep on and not fall off of. Make your own baby food from the fruits, vegetables, meats, and grains that you buy for yourself. Buy used baby clothing or receive hand-me-downs. Pretty much the only thing you might want brand new for a baby is a car seat because it is the law that a baby is in a car seat currently within regulations that has never been in an accident. You can't leave the hospital if you don't have a car seat that your infant can fit into. If your infant can't fit into the car seat you have, you _have_ to find a new one before you get to go home. Use the living room as the baby's room for the first 13 months-10 years if you live in a 1-bedroom. As the child reaches puberty, however, it's customary in America to allow that child to have their own private space. I don't see why this is a negative thing, to allow their own room; I don't see what's wrong with upgrading from a 1-bedroom to a 2-bedroom place. Business people of the future will likely not be as interested in the lack of regulations that currently govern modern business practices if what Millenials and Gen Z are saying now is anything to go off of. But, seriously, you give too much credit to the business world as being the desirable, profitable industry to go into. Computer science, specifically coding and programming, is where the money is at right now. So that's where the economy is headed.
why does the graphic show a definitely not 2mm sized pin pointy end? it is not a good example, i thought hank was talking about another kind of cell altogether from the graphic.
Thanks a lot. Your videos are amazing and interesting. I watch them after studying each system in my textbook. They are more beneficial than the silent pictures in the book. Thank you!

Mothers are amazing! They have to go through temporary pain for a lifetime of happiness. Thank you mothers!
sometimes i feel bad for my mommy ;w;, she had to go through the pain with me for 10 months.
TheCraftingCookie lol at you thinking motherhood is happiness

+GreenShot They also have to more kiddish version.
***** Well they never had a reason too.
Im not s child but i watch it all. My county lacks reproduction and sex ed because.. Religion.
Hakan Karaağaç what country do you come from?
Turkey. Formally secular but going more and more religious conservative by the leadership. Im the last generation that finished highschool with reproduction lessons in humans in biology.

is it sad that this channel has taught me more than my science teacher had? 😂
o be honest, yes. There's so much shame on sex and reproduction in school.
i had health class, but these videos are much better at explaining things, even though my teacher was highly entertaining.
+EvilNeon * entertaining *
+Enzo Ciarlini no puns, he literally was a great teacher.
Zory Fahringer why do u think I'm here? LOL 😂
All this pain and tears from all mothers in the world has created us. Thanks to all mommys in the world! With your altruistic behaviour we can live.
+Nathan Pattison Some women aren't ready to have babies. No reason to shame them for not being ready to go through this long, difficult process.
+Nathan Pattison The human population is going to hit 9 billion this century (assuming all goes well, and hopefully it will peak there).
+Emily Ericson I'm not shaming them, I'm shaming us for telling them it's ok to murder another human being just because that human being can't speak for his or herself. I feel anger, yes, but I don't hate anyone. A person's a person, no matter how small

I shall save this video so that everytime I have baby fever I can rewatch this and be reminded as to why that is a bad idea.
Right exactly
?
Girl I got it bad too, so I just watch as many scary delivery videos as possible & pay close attention to how evil the little things can potentially be at 3 & that helps me remember to wait till I have a degree before becoming a mother.
Of course you shall save it, you are American. and what Americans know best then put a baby in the world every nine months???

I have had 2 vaginal births can’t wait for my next little buddy. I love being a mom
Happy Mother's Day! And good luck with everyone on their AP biology exam tomorrow!!

Finally. An answer to the age old question: How is babby formed?
how girl get pragnant?
+Sugoi Hands sex
Is she Bregnant

6 months plus 2 weeks......
PREGANANANT!?!?!?
Thank you so much. Your human reproduction videos are excellent. I am glad you don't feel awkward talking about it because your videos really helped me to understand it.
I'm 7 years old but I want to be a good doctor
If you're already watching stuff like this, you're well on track. Keep it up.
Omg, kid you can spell better than most adults, it's a lot of work to be a doctor, but my advice is to study and never give up! Good luck!
My advice is to start looking at chemistry videos now and get good at chemistry as well. You're off to a good start. Good luck!
Luciana Love Your comment just make me feel sad, is it true.
Keep it up!! You´ll have a long journey but it will be worth it!
Or, in Gaius Julius Caesar's case: "It involves a system of hormonal signals that, as sophisticated as they are, get interpreted by the very earliest human cells into two simple instructions: Divide, and Conquer."
That applies more to cancer than fetuses.

Lol
I laughed out loud when he said the baby will combine aleles with someone
Me writing a test on embryology: I bet this video will help
Hank: So we won't focus on that
i like how Thought Cafe did the illustrations. . . .

This is what I'm gonna show my son when he asks me where babies come from.
And that is literally how all of us got here.

As a geology and geography major, all of this biology talk kinda freaks me out
i have a science test tomorrow, thanks so much dude you’re a lifesaver!
i like the way he teaches. and i wish he was my bio teacher.
very true
how do i know if I'M prengan?
could i be gregnant?
am i pergenat?
is it possible i'm pregananant!?
The first thing that popped into my head when i saw my positive test was, oh i'm pregananant 🤣🤣
You just need a Luigi board
what do you do when before the video there is an hour long "pre roll"?
Theses videos should be in schools
So scared of pregnancy atm😂
Pregnancy is fun in the 3rd trimester. Getting past the 1st trimester is the most difficult. Just know that when people say 'contractions', that means that you will receive a pain exactly like your period cramps, only more intense.
So if you are having twins do you have more than a 40% increase in blood?
wow what amazing you are thinking...
I watched ur videos while preparing for my medical college admission test and now when I finally got admission (thank God) I’m still watching ur videos. ✌🏻😍
THAT WAS AWESOME! I NEVER STOP LEARNING!

did you want that part of the video to be three hours long and fill of screaming? me neither.

Does the newly conceived zygote have its own DNA and genetic signature? I've heard this before but would like other sources to confirm or rebut this
Your videos should get a lot more of attention then they do. Keep up the good work!
Let me tell u man ! U r simply awsome ...and ur videos ...i just got addicted to them 😄
please make a video series dedicated to microbiology !!!!
pls add a video for gastrulation as it is the most hard part

@@liwendiamond9223 Having a baby in the developed world doesn't have to be as problematic as you are claiming it to be.
Use glassware to store food instead of plastics. Use the city bus. Stay home to raise the child on one income because it's doable if you budget properly, plus, it's 2019 and there are remote online jobs and/or freelancing jobs the stay-at-home parent can do to add income to the household. I'd imagine remote online jobs and freelancing existed in 2016 when you made your post.
Use empty toilet paper rolls, wooden spoons, Christmas tinsel, everyday objects, _your_ old stuffed animal from childhood, as toys. Buy used toys or receive hand-me-downs. Use the public library for books, music, movies, iPads, laptops, free early development classes, etc. Use cloth diapers. Make your own laundry/dish soap. Have a safe, flat, hard surface the baby can sleep on and not fall off of. Make your own baby food from the fruits, vegetables, meats, and grains that you buy for yourself. Buy used baby clothing or receive hand-me-downs.
Pretty much the only thing you might want brand new for a baby is a car seat because it is the law that a baby is in a car seat currently within regulations that has never been in an accident. You can't leave the hospital if you don't have a car seat that your infant can fit into. If your infant can't fit into the car seat you have, you _have_ to find a new one before you get to go home.
Use the living room as the baby's room for the first 13 months-10 years if you live in a 1-bedroom. As the child reaches puberty, however, it's customary in America to allow that child to have their own private space. I don't see why this is a negative thing, to allow their own room; I don't see what's wrong with upgrading from a 1-bedroom to a 2-bedroom place.
Business people of the future will likely not be as interested in the lack of regulations that currently govern modern business practices if what Millenials and Gen Z are saying now is anything to go off of. But, seriously, you give too much credit to the business world as being the desirable, profitable industry to go into. Computer science, specifically coding and programming, is where the money is at right now. So that's where the economy is headed.
"Head of a pin." The graphic keeps showing the point of a pin.
you're the best hank
So amazing cant wait to have my own child....... when I'm much much older
almost done, just have A and P 2 lab for the fall semester, taking lecture over the summer lol.
why does the graphic show a definitely not 2mm sized pin pointy end? it is not a good example, i thought hank was talking about another kind of cell altogether from the graphic.
that animation was amazing
Starting to feel prepped for my exam, this has helped a lot!
So Hank, will there be an A&P episode about death hosted by Hanksock?
Can I just take classes for credit already with crash course?? is this possible ! I know I'm just one neuron
AWESOME!!
Thank you CrashCourse
Thanks a lot. Your videos are amazing and interesting. I watch them after studying each system in my textbook. They are more beneficial than the silent pictures in the book. Thank you!
You guys made the baby's head so freaking large in that animation, jeeeeeeeeeez, made my ovaries pucker.
Please post a video on human regeneration. Please hank please.
You are just a legend
