The immune system has two main branches: the innate immune response and the adaptive immune response.
The innate immune response includes cells and mechanisms that are able to react to pathogens from birth. The adaptive immune system can learn and remember new pathogens and then protect from them long-term.
The innate immune system is composed of:
1. physical barriers such as mucous membranes and skin
2. chemical barriers such as lysozyme and stomach acid.
3. Complement is a group of small circulating chemicals that, when triggered, form a "membrane attack complex" that can punch holes in pathogen cell membranes.
The leukocytes that are involved in this response include:
*Granulocytes - neutrophils, basophils, eosinophils
*Agranulocytes - macrophages and dendritic cells, which can be phagocytic and present antigens from invaders to the adaptive immune response cells known as helper T cells.
*Lymphocytes - Natural killer cells (NK cells) can cause apoptosis of tumor cells and viral-infected cells.
The adaptive immune response includes T and B lymphocytes. These cells must be activated to a specific pathogen before they can respond.
Helper T cells stimulate cytotoxic T cells to directly destroy pathogens. Helper T cells stimulate B lymphocytes to enlarge into plasma cells and produce antibodies.
These lymphocytes all reproduce rapidly and form memory cells that remain circulating and passing through lymph organs long-term to patrol for the presence of the specific pathogen in the future.
All leukocytes are formed in the bone marrow in a process known as hematopoiesis.

You’re the best! I’m a 64 y/o that’s returned to school to earn my nurse practitioner license. It’s been many years since I first learned this, your videos are awesome!
That is awesome!!!
Agree !
@@lindascanlan6317 Im 58 and in nursing school. I GET IT!
Very good
I recognize your voice from Khan Academy. You can run but you cant hide. Ha ha ha
you are literally saving me with my nursing masters! shared your page with everyone in my advanced patho class!!!!!! love love love your youtube videos
Can you make more videos on the other systems!!! THis is sOOOOO gOOOOODDD THANKS I literally LOve you !!
I saw this channel for the first time and can I say, I really appreciate your work 💪😊 I am very bad at making short notes 📝😅 but luckily I've found you So thank u. You just earned another 🌹SUBSCRIBER🌹❤
For some reason I'm watching immune system videos for no reason. I'm not saying the videos I watched are bad. I just have no idea why I'm watching them.
I thought cytotoxic T cells killed infected body cells, not pathogens. pathogens themselves are killed by having antibodies stuck to them, which macrophages recognize, and this causes the macrophage to engulf the pathogen. Really nice and organized video though!
same here. from previous class I have that cytotoxic cells attack foreign cells or body cells infected by viruses.
Very well done as always, thanks so much! 👍👍. I love the way you explain the meaning of the words, it makes everything much more clear.
I got question in teas exam which cell suppress T cell cells -
a- t regulatory cells
B- B cells
C- plasma cells
D- antibodies
I found answer that it is regulatory cells , but don’t know process plz explain it
I had questions in teas that patient had wound on skin,when pathogen enter through wound and then which system will help to kill the pathogen
Immune system
Circulatory system
Integumentary system
Lymphatic system
IMMUNE SYSTEM
Wow that was amazingly helpful !! Straight to the point but yet very descriptive!! Thank you!! You’re awesome!!
you help my medical school life become much better, this is what I need, I’m so bad at summarizing and here you go♥️
Why do the Macrophages look like pac man
HAHAHA this was fun to watch honestly!! you´re amazing
Thank u so much. This video was very much helpful !!!. Would you please do a video about lymphatic system ?
This was very helpful!! thank you, would you please do a video on the lymphatic system?? thank you :-)
Yea on lymphatic system too
I've had the channel for a few months but I have returned specifically for lymphatic system!
All video are helpful...thankuuu...please make summarized video on hypersensitivity,pneumococcus
Me too about hypersensitivity
Great summary...Concept clarity superb...The sequence of presentation....sooo good..Well done
Thank you so much:)
This is an exceptionally informative and well-presented video. Thanks for uploading it. I have shared it on my FB page because on there, the way people think nowadays they seem to rely too much on drugs and other therapies for disease and ailments.
Go DO!
Nice to see your knowledgeable video again..... Thankyou
Why did I only find this video one day after my bio exams :(
Why not write up your chart beforehand? Just out of respect for listener?
This is a very nice summary including well organized and nicely visually displayed with color coding. This brought back fond memories of my medical school lecture notes taken with my big, thick multi-colored pen.
Thank you for stimulating those joyful memories.
Eosinophil means Eo or Eos - dawn (of red colour thus) so as it stains red it maybe means it is 'acidic' (but note it comes like most medical terms either from ancient Gk. or with some others from Latin). 'Phil' always means likiing or loving. It is a bit moot and a quibble but I am interested in the etymology of words.
Actually, the name "Eosinophils" is named after the dye "eosin", which is red in color.
Eo or Eos mean "dawn" like you said.
thank you so much for your videos
Thank you so much I love your videos
Why don't antigen presenting cells recognize antigens in some disease such as hepatitis B? Or is the problem with the T helper cells? How do innate immunity cells know when something is foreign?
Bacteria flora on skin and gut also competitively inhibits pathogens , I think they also can be included in innate immunity .
Better than the osmosis presentation of the immune system ...thank you
The info helped me thank you. Presentation of info good, but cd be great
you have a very nice way to conclusion every ideas together and make them sense
so helpful! Great summarizing! Thanks for making this video
You are amazing in explanation. Thank You!
Thanks you very much you are legend ❤️
Keep going
Really nice video ! Thank you )))
Why do we have to watch you write?
You weren’t forced to watch the video. The idea is to learn while she writes.
There was no forcing of you to reply
And I know of no person who learns by watching a pen move across a bd
Lmao, I learn by visually seeing things and following along. Find another video then sheesh.
AME should test health professionals annually on education, considering the prepaid educations during college years in a video conference, nothing to do with video
SO GOOD! I'm studying for the TEAS, and this is so good!
it is very helping!! thank you so much
Products from PLANET AYURVEDA are also help the individual to boost their immunity system with their natural ingredients
Thank you so much 💐💐💐💐💐💐💐
THANKS for sharing. Great review
Amazing! Organized review to help put all these cells in their proper places
Hank says that B lymphocytes mature in bone marrow. Not in the lymph system
For adaptive immune better- Whatever doesn’t kill you makes you stronger
😂
Could we get a pdf of your video please especially the picture of your headnotes please. Thanks
Can you make more summaries for all of the body systems on your videos. I know there's this one and the hear one and that's all I could find. It's great for a quick review for science especially since some people don't have alot of time to study for the teas science section since science is so broad.
This is the best learning channel🌸👍
All the contents in your website is just awesome, perfect study materials for students like us.
Hey sussane ,can I use your knowledge in my videos
THANKS for sharing..great notes..
This was extremely helpful thanks!!
Your note is so colorful. I love it

thx so much
You are amazing!am 20 y/o am doing pharmacy your video are awesome ❤
Uu have so much videos on uur channel and their all so helpful
Cheers-
The enemy: in the exoskeleton of vectors like mosquito are parasites like malaria, filaria; bacteria from the skin, virus including dengue, phages and bio-peptides. These gain entry past the Skin (first defense) during a blood meal
In the case of corona virus🦠😷, the virus enters the lungs when temperature drops to 21°C or lower due to cold wind and rain exposure. When surfactant and alveoli are damaged, breathing is unsuccessful and hypoxia results. Thus the primary or innate immunity is breached.
Vaccines against COVID-19🦠😷are lifesaving.
Vitamins and mineral supplement help strengthen the innate immunity.
Excellent!
Brilliantly done...thank u
I really love your works ❤️❤️❤️
Hai, your channel amazingly helpful...hopefully there's topic about oncology on your next video 😅, tq.
where monocyte
monocytes form macrophages
I am in grade 11 and studying life science and i found this very helpful along with the flashcards. love the writing especially in colour
Thanks for making it so easy.
Amazzzzzing ♥️
Chemical Barriers commonly found in our bodily secretions are: (1) Lysozomes, (2) IgA (A.K.A. The Anti Septic Paint of our mucosal linings, because they are present in EVERY mucosal surface), (3) Lactofferin, and (4) Amylase (the digestive enzyme mentioned in the video).
Incredibly well presented summary! Really helps tie it all together. Thank you!
Very good presentation
