How Your Body Heals Cuts, Scrapes, and Puncture Wounds to the Skin

- MEDICAL ANIMATION TRANSCRIPT: An injury to the skin, such as a cut, scrape, or puncture wound kills nearby cells and damages underlying structures and triggers the complex process of repairing the skin. Wound healing is a three-step process. The inflammatory phase begins immediately upon injury. Blood vessels constrict to reduce blood loss. Then, platelets arrive to plug the leak. The platelet plug initiates the clotting mechanism by facilitating the reactions of plasma proteins called clotting factors, which interact to form a fibrin clot. After the clot forms, the blood vessels vasodilate and become more porous to allow white blood cells to leave the blood vessel and populate at the site of injury. During this process called phagocytosis, white blood cells eat debris and kill bacteria, reducing the risk of infection. The proliferative phase begins two days to three weeks after injury. The first step in the proliferative stage is granulation. Connective tissue cells, called fibroblasts, lay a matrix of collagen that reinforces the wound and provides structure for other cells. Collagen then contracts to pull together the margins of the wound. Angiogenesis, or the growth of new blood vessels, begins almost simultaneously and supplies oxygen to the repairing cells. Epithelialization is the restoration of the protective skin barrier. Epithelial cells migrate from the margins of the wound, protected by the scab, until they meet. Eventually, the scab falls off. The remodeling phase begins several weeks after the injury and can continue for years. During this phase, a new, more organized collagen matrix forms in the wound bed and capillaries disappear, leaving an avascular scar. One possible complication of wound healing is keloid formation. A keloid results from an overgrowth of granulation tissue extending beyond the borders of the original wound. Composed of mostly collagen, keloids are slow-growing. They do not regress spontaneously, and tend to reoccur after excision. A common initial treatment for keloids includes multiple injections of corticosteroids to help reduce the size of the scar. ♪ [music] ♪

There's theory that say platelets draw as kindergartens is because platelets only live for several days

When you realize, your body loves you more than you do yourself! 😭🙏🏻

Now I feel bad, all this work just because I goofed with the kitchen knife
But pizaa is worth it
Like they used to say on hee haw the guy said to the Dr’ doctor it hurts when I do this and then he smacked him with his hat and said well don’t do that,,,🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣
Bruh, I just cut myself with the kitchen knife this week too.
Got them cells working overtime.
As a child I almost cut my thumb off while trying to cut food. To this day I still have a scar and it’s pretty noticeable
I had a small pocket knife I was trying to use it to open the chalking bottle to place it in the gun. Knife slipped tor open a gash in my left index finger. It cut me deep. I wrapped my finger in duck tape and headed to the hospital. The doctors face turned white when he saw the cut. He said I sliced through two skin layers almost to the bone. I got stitches to hold the cut closed that was fun and in 6 weeks I was all healed up I was surprised it healed so quick. I have a small bump on my finger it healed all funny but my body got the job done dosnt even hurt anymore I forget it even happened until I look at my finger.
It's mind boggling how sophisticated this system is.
Like something only an all powerful and all knowing creator could have come up with.
@@Ntmoffi Exactly. Anyone who doesn't know Zeus and the pantheon of gods are real hasn't been paying attention. This is the handiwork of Asclepius.
They possess a high intelligence of thinking. They know keeping you alive keeps them alive and their descendants alive. Youre their host. They are intelligent organisms much smarter than yourself as a matter of fact, your brain is also smarter than you. Its a living organism or membrane capable of making decisions for your body and for your microorganisms living in you. A system of contracts that each microorganism agrees to servicing.
@@NtmoffiYou bore me
@Ntmoffi 100% correct sir.
Remember scab peelers, not only are you gross, but you’re literally undoing all the work your body is putting into making sure you look normal again.
Ok yea but it’s fun
You ain’t my mum

Jokes on you, I'm trying to sabotage my healing
“The scab protects the wound as it heals and binds togeather creating a new healthy layer.”
*Me not picking the scab off 3 times every time it forms*
“STOP INTERRUPTING THE PROLIFERATIVE PHASE-“
YEP SAME- it's just so annoying when it's there and satisfying when I scrap the scab thingy off.
@@AcademicJaedoncan you elaborate more on how outer scabs restrict blood flow? I’m confused a bit
@@AcademicJaedon im also interested in hearing why they're inconvenient
@@AcademicJaedon(see below comment) I don’t see how it could possibly reduce blood flow *in a bad way* seeing as it exists, in part, to prevent bleeding.
@@SecureHandle I actually did a bit more research into this: scabs dry out the wound, which reduces the presence of the fluids required to get repair materials to the wound. This *does* reduce bleeding and chance of infection, but also increases scarring and time taken to heal the wound. In general you should keep your scabs warm and moist, as this allows the wound to heal faster while still not exposing it. Lots of ointment can also keep scabs from being ripped off by applied bandages, but in that case it’s better to just replace your bandages more often.
The human body is simply amazing.
The living body is amazing
Makes me feel better knowing that my body is smarter than me.
Right!? It's only job is to keep us alive for as long as possible, yet we sabotage it daily
It’s pretty amazing that our bodies do all this. We take it for granted, but it truly is remarkable!
Why it’s important we take care of our bodies so it can take care of us.
The hardest part of wound healing is, of course, fighting the urge to peel the scab
She sounds like she's educating me on plumbis construction
If you had the keys to your body, you’d be dead in a week; so very many little things working together to keep you alive. Have a little faith and trust the process! The universe is working in your favor.
Tell that to the 3 tornadoes that hit my town at the same time on the Friday before Mothers Day.

I came here for information but got the best physiology animation as well, amazing work!
Angiogenesis, and the animation for it, is my favorite part of this.
Never peel your scab guys...
it’s so hard not to tho 😵💫
It's very itchy tho
Cant... Too... Tempted...
i just cant
Okay I will peel others' scabs
I had been in a biking accident once and I have wounds all over my body.The wounds are It's really severe to point that every wound have this burning feel to it. I even got a bit of fever back then. Luckily I didn't break any bones. I just let the fall roll me onto the ground. I even got keloids on a big wound in my knee but it diminishes as time goes on. The healing process took like a month where all wounds are close and I can move back to normal but inside the wounds it's still healing because I still feel pain in my wounds. I didn't go to the hospital or anything I just rest at home clean my wounds and change bandage everyday. I took some painkillers so I will not be pain all the time and eventually my body heal itself back. We took it for granted by it's just amazing how our body can fix itself. We are even better than machines. I mean machines when it's broken you need a Repairman to fix but our body can cure itself on its own without relying to anyone.
A visit to the hospital when reasonably possible is still recommended, to anyone who reads comments who downplay health issues like these. Evolution gave us the manufacture and maintenance, people developed the tools to make both easier.
If you got a fever you should go to a hospital. Also dont take antibiotics unless your life is directly or indirectly in danger
I just got this video recommended to me. Thanks YT!
"zack makes the most satisfying animations"
NMM: Hold my needle
Needle..? You couldnt think of something better? Jeez.. I feel sorry for you
@@Bretaxy dang who bent your needle
That is so interesting. I always wondered how all of those differentiated cells worked together. They never taught us this in biology.
Most of what students should really learn isn't taught.
I've actually been thinking about this a lot lately. I pinched my fingertip when pliers slipped, and got a blood blister that immediately popped. I've been watching the healing process for the last couple weeks, appreciating the work that my skin is capable of.
Intelligent design. Glory be to God
I’m really afraid of blood and blood loss to the point where it’s nearly a phobia- videos like these really help me understand how cool and powerful our bodies are while also being abstract enough to not bother me. Knowing how wounds heal helps me deal with the fear too. Great video!!
Thanks for this helpful tutorial 👍
This is the tutorial i needed
This video and the process is dope
Amazing work, very informative, easy to understand! 👌🏻
I've hurt myself that many times my body heals super quick, I should be dead really, but the body is an amazing thing
Best part is the classic scab peel. Refreshing
“Eventually the scab falls off”
Me: always picks the scab
Fascinating
Impressive on how our bodies can repair itself.
On the other hand, it's kinda fucked how every little wound just turns into scar tissue and not even trying to rebuild normal cells there.
This is the first time I heard about blood veins regrowing! Somehow I imagined they just clog and disappear if they are cut. And I tought that in surgery they have to reattach every vein or else the blood won't be able to circulate though there anymore. 😵💫
Can you show the healing of ligament?
Healing of torn ligaments is a complex process with multiple variables.
I doubt it could be explained in a video.
If you have torn ligament, talk to your doctor for a better explanation that will address your situation specifically.
Yes!!!
Does it ever get back to the original state? According to the imagery in this video, seems like there’s always a sort of permanent damage (likely dependent on how deep the lesion goes I guess).
Nevertheless, fascinating video.
This is indeed educational!! Glad that I came across this video!!

You have good content
Truely amazing how our bodies does all this on its own.
and yet. those moron says no one engineered this amazing phases. they believe universe created by mere coincidence. praise to almighty Allah, the most holy, the true fashionist, the alcreator of skies and earths, and everything inbetween
Today I learnt that apparently people peel their scabs off 🤨
So cool
Our bodies truly are little tiny universes in and of themselves❤
I have a bunch of random scratches in various stages of healing on my arms. It’s interesting to look at
I shave with one of those Henson razors that some youtubers have talked about. It's like one of the old timey safety razors but modernized (and better) . But you still have to change the blades and those little buggers are SHARP! Even when they are past their effective shaving sharpness. Lemme tell ya' Don't slip up if you use one. Henson, or otherwise. I watched this video with the cut on my fingertip in mind the whole time.
Awesome video, thanks for sharing!
this is so relatable fr
Thank you, voice from the beginning of half-life
Respect ❤
amazing animation!
Thank you Diana Troy, but arent you the ships councilor? Wheres Dr. Crusher?
For all the complaining we do when our bodies malfunction, gotta appreciate the immense complexity of all the mechanism that keep you from dying every day.
All the miracles of modern medicine are dwarfed in comparison by the miracles of what our bodies do in even the smallest healing processes.
Scars don't happen all the time, just a heads up.
A small cut and this much work my body does a lot of work for us and we waste it by fighting friends and get cut and bruises. 🤣
Your body after the fight really be like “Again, Jim? You need to stop doing this… alright, let’s get ya fixed up… what do you mean you’re fighting again tonight?! MOTHERF-“
The human body is wild.
When you're feeling alone, remember the little critters inside you are always there to protect you.
2016 was a wild time.
Does a very small cut, or a needle puncture also leave some permanent avascular scar?
What was injected into the keloid formation? An antibiotic?
आपका काम अच्छा है
It's so cool there's an anime of it
If you use verteprofin, there will be little to no scaring whatever.
You can even regrow organs like hair follicles
No idea why this was recommended, but I watched it.
Our cells bestie are really helpful we should eat more veggies as a reward for them
Be nice to yourself, and never feel lonely, because billions and billions of your cells are fighting for you and protecting you with their lives.
Very nice overview. Keloids are common around ear piercings.
Human lore just dropped
damn, my body is fricking awesomesauce
I've found out that creatine aids in healing by not allowing to bleed as much. Not sure why but after I started taking it then getting scrapes or cuts the clotting of the skin seemed to hasten speeding up recovery
The fact there’s all these little creatures throughout my body dying just so I can be in the best shape I can be keeps me going
I’m doing it for you lil dudes, don’t let me down
I wonder if you could live long enough would you eventually have so many scars that your body couldn't function?
I once had a thing on my nose from 7th grade until I got it surgically removed in my 20s that would pop off from just slightly touching and bleed for hours.
This is interesting, but I still wonder why when a wound is healing sometimes it's itchy?
It's because of all that activity and in fact it's a good sign.
Because your skin is pulling together which causes irritation since it its literally your cells coming together to make new ones
Neat! TFS, GB :)
Nice and informative, but I had to watch it in 1,25 speed for it to bearable
Can you explain “ulcers” ?
I have leg ulcers (not diabetic)
These take months/years to heal.
Try magnesium supplement. It's extremelly cheap too. At the drugstore ask for epsom salt. Add a bit in your food everyday (don't exagerate bcz its laxative 😄) and you can also bathe in a bathtub with magnesium mixed in the water. I hope it helps.
This is actually an incomplete restoration since wounds are filled with collagen, not actual tissue. Always use topical medicine that promotes of regeneration of actual tissue.
Yes, it really shows BIG difference when using it compared to just letting it heal naturally(although natural healing also does complete regeneration sometimes. I don't know specific cnd)
now I'll think twice before constantly picking at spot scabs, like damn that keloid lump looks scary asf 😭
Are scabs protective for skin or not???
So am I to understand that older people take longer to heal since they how lower collagen?
I think it's about time to go to bed now
True. I can confirm.
Don’t pull your scab off even when it’s “ready”. It’s only ready to come off when it comes off by itself. If a bit is hanging off just cut it off, don’t peel the whole thing.
My thumb totally experienced no accident yesterday.
i love nucleus media because precise animations give us clear medical concept and amazing virtual videos for our learning...
❤
that is why i am biologist now.. 🎉🎉
“Yeah this all just evolved due to random chance.”
talks about days, but what about a tiny cut from shaving that closes the next day?
Would love to see how wolverines healing works 💪
Notable lack of the mention of fat cells, which play a large role in wound healing.
Subhanallah ❤
2:23 that thing tastes so good!
???
Watching this as my wound from surgery has finally started scabbing and me wanting to itch it off so badly.
I'll suffer through the itch
Great vid
This feels like an episode of inter dimensional cable
I heard wound don't heal, but continuously repair until you died, it could reopen if the body ran out of material to repair them (some vitamin or something)
Its basically a super power, amd just to think that some small animals that can actually regrow limbs will get you thinking that maybe theres some life form out that that can actually regrow major limbs
I have so many scar on my hands but they're small to notice
I want to thank all the cells in my body for their service🫡👍🏻
This makes my body feel numb and my hands feel weak
I like how people think differently than their bodies. If only the body could somehow talk to you thru your brain that you shouldn't peel that scab off.
It's very intriguing that yesterday i got into a minor accident where my hand was scraped, and today this video appears in my feed as a suggested video. 🙄🙄
Them cells making me want some lifesavers
