To the correct is an image to help you see what is going on. Within the subcutaneous layer (you will have heard of subcutaneous fats -- that is where it lives) you can see the blood vessels (shown as two skinny red and blue traces). These vessels branch infinitely (not proven) into the dermis to provide the sweat glands, hair follicles, sebaceous glands and erector muscles with blood. In addition they fan out into the dermis's capillary mattress. It turns out that the dermis is loaded with capillaries.



Capillaries fulfill the nutritional needs of the cells within the dermis, and BloodVitals SPO2 they also assist the skin carry out an necessary cooling perform in people. The epidermis has no direct blood provide, however as an alternative is supported and fed by the dermis.
