Superficial; stratum basale; keratinocytes; corneocytes
____ wounds penetrate blood vessels. Blood fills the wound and then _____ into semi-solid mass. ________ in the clot mature into macrophages; neutrophils in the clot work with macrophages to destroy invaders. Cells of the _____ _____ migrate inward to replace the epidermis. _________ migrate into the dermal portion of the clot and lay down a new fiber matrix to restore the function and appearance of the ______. If the restoration of the dermis is not complete, a ____ may be left behind. Some scars ______ over a period of several months or even years.

First degree burn
only the epidermis is involved. The skin reddens, but there is no permanent damage and the skin returns to normal in under a week.
Second degree burn
the heat energy penetrates deeply and both the epidermis and deris are damaged. Blood vessels leak fluid (not the cells), and blisters form as the skin fills with the filtrate of blood. Hair follicles and glands are typically not damaged.
Third degree burn or full-thickness burn
destroys all layers of the skin. Cells die and the skin function is lost in the affected area. The dead skin may be black, cherry-red, or ash-white.
