Eli5 when someone gets an injury that requires a skin graft, how does the area they take the graft from recover?

I’m assuming they stitch it but can’t stitch the original location for some reason but I still can’t wrap my head around it?

Hi! Just to clarify somle stuff, grafts can have various components:

1. They contain the full thickness of the skin that consist of all layers from epidermis( the outer part of the skin which contains mostly "protection" cells of you will) + All layers of Dermis( the inner part of the skin which will actually be responsible for the sustainability of the graft as it has the blood vessels required for it to keep living)

2. All layers of the epidermis + the outer layer of the dermis

3. Epidermis + Dermis + any other tissue

Usually there r parts of the body that can have some skin removed without any major consequences and can deal with the loss of the skin, in which you take the skin and by closing that wound it will heal easily and not be "bothered" by the skin slowly covering up the area again by stretching a bit while the underlying area of the skin being filled with scartissue

Usually the site from which the donor skin is taken is selected by where you want to replace the skin, thinking that it should match it's new site as much as possible, as skin is is not the same width all around and can have more or less hair and "oily" follicles 


Don't know if that made sense so let me know!
