Stages of Wound Healing in 2 mins!

In this video, Dr Matt explains the three main stages of wound healing in 2 minutes!

[Jenny-kgjh]

1. Homeostasis:
Tissue gets damaged and blood vessel below gets ruptured, causing wound to get filled with blood, forming a blood clot and scab on top which then encloses

2. Inflammation:
Blood vessel dilates and makes area swollen, white blood cells enter area to get rid of bacteria and dead cells to prepare for proliferation

3. Proliferation (healing and forming new connective(granulation tissue and epithelial tissue):

Fibroblasts cells enter wounded area and release growth factors and collagen that cause blood vessels to start forming. (Angiogenesis). Connective tissue, composed of fibroblasts, blood vessels, and collagen, forms on the wound. Wound contracts to pull sides together(Contraction)

Fibroblast growth factors produced by fibroblasts will control the migration, cell proliferation, and cell differentiation of fibroblast cells, and epithelial stem cells like epidermal cells and keratinocytes.

These growth factors triggers the process of epithelialization in which new epithelial stem cells will migrate to sides of the wounded area, multiple itself through cell division and proliferation, and then differentiate into specialized cell types needed to replace old damaged or lost cells, and move from those opposite sides until they meet to fully cover and enclose the wounded area. These epithelial cells are what makes up the epithelial tissue formed during proliferation. (Epithelialization) Epithelial cells can also produce growth factors.

Then the growth factors produced by both epithelial cells and fibroblasts will attract more fibroblast cells and cause them to divide and then produce collagen which further strengthens the epithelial cells and tissue in the skin

4. Remodeling: Strengthen scar tissue

Thank you sir. Pretty important topic for my tomorrow’s pathology paper.

Who is watching with a wound right now?

[mannysanchez]

I learned more here than I did in my one week on the integumentary system in my A&P class

[ad]

Thanks you did better than the video of my class

[drskellybones]

we passing our exam with this one guys!!!

Human body is very interesting. We are so rare we don’t even know it. Treat your body good it works for you every day till you die.

Hello Dr. Matt. Great video! Quick clarification, during the proliferative phase, is it the fibrinoblasts that release growth factors that promote angiogenesis and re-epithelialization or is it the macrophages that do this?

[lynann]

I had flesh eating bacteria. Is the healing process the same . Thanks for any info you can give me .

[smiley]

what should to used for deep injury so that it can heal well

[JO-mgxc]

To accelerate wound healing a no contact dressing works well. It is called Podophylus antimicrobial Insole and DermaDomus, both allow oxygen in the wound….

siir plz help me, the answer and mechanism. thank you for helping me, i appreciate your teaching me.


A 58-year-old man with a history of deep venous thrombosis following right total knee replacement is recovering from multiple injuries sustained in a motor vehicle collision. His injuries include fractures to both tibial plateaus. He is on subcutaneous unfractionated heparin for prevention of deep venous thrombosis. On his 6th hospital day his platelet count dropped from 250, 000/μL to 110, 000/μL. He is otherwise recovering well with no complications, and a lower extremity Doppler is performed, which is negative for deep venous thrombosis. Which of the following additional tests would be most helpful in determining the cause of his thrombocytopenia?
A) PT and PTT
B) Anti-platelet factor 4 antibody …
c) Protein C activity
D) Protein S activity
E) Factor Xa level

Is this considered as a soft tissue healing

who is watching this vedio right now.... ❤

Watching it with multiple stitches above my right eye 😂

What Do You Do When Your Opening Wound Is Tender

[keegancan]

If a wound is to be infected how long does it take? I cut my thumb if that helps?

[emilylacerda]

So during inflammation will it make around the skin to swollen??? Is that normal

[LovelyMontinola]

can this be consider as ''Tissue Healing'' ? please reply :)))((((

[masterthenotsobasics]

I scraped my knee and right now there is a yellowish layer that i think is pus thats why im scared its getting infected. I keep it clean regularly as well. Is this layer normal?
