What about tissue rejection?

[basemjs]

@jjkul1 This video discusses "Auto-Graft", i.e. the skin is taken from the same person doing the operation. So, it is actually his own skin. As a result, there is no rejection.

Rejection happens in trans-donor Organ Transplantion.

@basemjs Alright, thanks.

[Wolfz115]

uhhh. one question i would liked answered.

what about the blood vessels do they get replaced?

cause half of the blood vessel is missing

[basemjs]

@Wolfz115 The blood vessels are in the hypodermis. This layer is not included in the graft!

Great article.

Alright so I have a wound on my ankle, they take skin from my leg to fix it. Where do they take skin to fix what they just removed? What, do they just keep going grafting and replacing until I look like a patchwork quilt??

[Breathlless]

@Vargsy no, there are different skin grafting techniques.

usually they need skin grats because the wound is too large for the skin to heal properly.

they would simply remove skin in smaller pieces from several sites and piece them onto your wound.

they then let the area they just removed skin from heal normally.

@Vargsy The skin on your leg is healthy so it'll grow back, whereas the skin on your ankle is so badly damaged that it cannot do so.

[MMBNM]

She said three main layers....how many layers of skin are there

[acuchemkid2007]

@MMBNM It can vary depending on the area of the body, the heel of your foot has the most and your eyelids have the least. Generally from what I remember it is about 10-12 levels just for the epidermis. Just a guess though.

[YurNotSpecial]

@acuchemkid2007 It was a reference to tissue layers. Meaning: epidermis, dermis and hypodermis.

AMAZING!

I want to be an surgeon when I grow up ^^

[x3Heroiinex3]

@Rodrighus you have to work hard for it

[MzChelxoxo]

@Rodrighus they made this look so simple with the crisp graphics, but it really isn't.

I have always wondered - what happens to the donor site, especially in the case of a full-thickness graft? Are you not left with the same situation as before?

[dudette201]

@1RadicalOne I think the donor site will repair itself as they say that they'd use a skin graft for wounds that won't heal. So perhaps they take it from an area where they're sure that it can repair itself without a problem, and obviously the donor site in the case of full thickness will have to be washed, packed, bandaged etc.

But jesus, did that thing taking off the split skin graft look like a vegetable peeler or what? *shudder*

[1RadicalOne]

Except that the graft by definition must be deeper than the original wound (since they cut a margin around the injury). So if the original one was too deep to heal, why would a graft not be too deep?

woooooow
