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] ♪

Gotta thank the little guys keeping my body in tip top shape :)
@@YourExcellencysaying “thank the little girls in your body” is wild
@@jokes6491Its an anime reference to “Cells at work” where Platelets are shown as kindergartners
There's theory that say platelets draw as kindergartens is because platelets only live for several days
Oui oui

When you realize, your body loves you more than you do yourself! 😭🙏🏻
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
*eats it*
I dun wun luuk nurmul
Jokes on you, I'm trying to sabotage my healing
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.
Now I feel bad, all this work just because I goofed with the kitchen knife
But pizaa is worth it
“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 but
@@AcademicJaedon im also interested in hearing why they're inconvenient
@@AcademicJaedonI don’t see how it could possibly reduce blood flow *in a bad way* seeing as it exists, in part, to prevent bleeding.
She sounds like she's educating me on plumbis construction
I came here for information but got the best physiology animation as well, amazing work!
It’s pretty amazing that our bodies do all this. We take it for granted, but it truly is remarkable!
Angiogenesis, and the animation for it, is my favorite part of this.
"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
Makes me feel better knowing that my body is smarter than me.
That is so interesting. I always wondered how all of those differentiated cells worked together. They never taught us this in biology.
The human body is simply amazing.
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
This video and the process is dope
Amazing work, very informative, easy to understand! 👌🏻
Can you explain “ulcers” ?
I have leg ulcers (not diabetic)
These take months/years to heal.
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.
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-“
2:23 that thing tastes so good!
This is interesting, but I still wonder why when a wound is healing sometimes it's itchy?
So cool
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!
amazing animation!
It's so cool there's an anime of it
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!!!
this is so relatable fr
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.. 🎉🎉
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.
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. 😵💫
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.
True. I can confirm.
Our bodies truly are little tiny universes in and of themselves❤
My thumb totally experienced no accident yesterday.
The hardest part of wound healing is, of course, fighting the urge to peel the scab
Who else got recommended this video after getting a bad wound
Great vid
Wow my body is so fantastic!
Meanwhile I will scratch the wound..
Thanks for telling me how I heal
Please do Plumbis next
La Vie La Vie La Vie !
There's an episode about that
How about wound without bleeding and scarring?
Them cells making me want some lifesavers
Which app or tool you used for animation kindly suggest me
blender
Potato
If inflamation is such an important step in our body healing. Why do we often hear that we shoudl reduce it?
I don't know why but I seen this as those cell at work anime .
Imagine enforcing this process on wrinkles and damaged skin without a real wound.
ie micro needling
How about scar after acne? Why it happened?
In the restructuring phase the type of collagen changes, as well as the density; that is what gives the white coloration. Acne can be caused by hormones, but can also be caused by pore blockage, such as by dirt, grime, skin oil, etc. (eczema is different.) The greatest contributors to scar formation are the length of the inflammatory phase (which is lengthened by infection and excessive fluid buildup), and wound size. In acne, the issue (generally) is in the inflammation phase, as acne often has a particularly long inflammatory phase.
Hey nucleus medical media can you make a video on affect of Toxins like heavy metals ( lead , mercury) or chemical ( cyanide, methanol) affects brain cells or neurons ??
Subhanallah ❤
the things i watch at 3 am...
if it doesn't reach hypothermis, you don't need stiches and there will be no scar
so thats where my blood came out
I have severe eczema so this doesn’t happen. Scab grows and i just pick it off
I have to die of something, I'm not here to live forever..
Wonder what improvements can be made to diminish scar tissue
I can't relate to this sadly.
Hemophile ?
Crazy how you don’t have to do anything….your brain will handle it by itself 😭
Why do the blood cells look like hard candy?
Truely Allah is the magnificant creator.
Now I know what happens when I SH
Good job, but the removal of that scab wasn't nearly as satisfying as in real life.
Makes me sad to think theres deep scares or wounds that my body i still working on. I used to think once the outer skin reocvers you should be set.
Thats why my leg injury it really looks like. i have a big scar and it grows but it was injury again and what happens.doesnt go grow again or it lift the scar forever.
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
So basically.... Im Wolverine
this kind of regeneration doesnt work if the cuts is huge like laceration(requires stitches)
❤
It’s a miracle how Allah has created us, Mashallah
😮
But how does the body even "know" of the cut? Like how or what instructs the platelets to collect at the injury? What mechanism tells the colegen to regrow?
This will sound crazy but your entire body is watching itself. That means if you get a cut your immune system is triggered via nerves and blood vessels and it senses that there’s a disruption in how the blood is flowing. You might be thinking of hemostasis in your last 2 questions, it’s fascinating.
So wounds remain a scar? But my wounds heal completely and vast majority of them, I don't see anymore.
💪🙂👍
So once you get cut that part of the body never actually heals to what it was before it got injured?
Its 2024 and this animation looks like its from 1990
Tattoo healing?
Thank you God for all your blessings
God doesn't exist 😊
🙏🙏
👍👍👍
Subhanallah. How can any sane person think that this perfect design has no designer? Thats just insane.
Allah doesn't exist
That's why the most important scientific discoveries of the last 500 years were made by non muslims
Oh so a scar forms? That’s why there’s still a line on my finger after I cut it really deeply
No way I'm gonna let them cut my keloids if it leads to an infinite cycle.
Amazing to know we have countless invisible scars under the skin.
6 mins ago?? 🤯
Huh, I was wondering how this works.
And to think, the prevailing scientific theory for how all of these amazing things happen is “well a lot of time went by”.
Looks more like something intelligent was involved here.
Good video
Yesterday I accidentally impaled myself with almoat an inch long piece of glass.
Its good to see how it heals.
I thought it was only a tiny booboo, but i just kept pulling, and the glass just kept coming.
Messy experience, but I think im okay.
Me 1 week later: 😵💀
Amazing the stupidity of some people. They don’t care the traditions, the good for the children. Pathetic.
Looks like lifesavers gummies
Please overlay this with Cells at Work
I like to think of the scabs as construction tarps covering up while construction is happening underneath.
Despite how tempting it might be to pick it off, Don't do it.
It’s melanin
2:56 ohhh it’s this annoying bump from scars that makes the skin look so awful
Almost first 🎉
Hmm interesting
On a scale of 1-Minecraft how interesting?
There is no God but Allah
God is so creative and good ! He is so great ! THANK YOU JESUS !! 💕
