Epidermis/upper dermis torn away, lots of particles and bacteria, capillaries torn

Arteriolar spasm, platelet aggregation, crosslinking of fibrin, haemostasis

Scab of dried protein (esp. firbin) & RBCs, thin layer of granulation tissue (edematous).

Protein-rich exudate accumulates, mainly albumin and fibrin

Thicker, more opaque epidermis, fibrosis, reduced BVs in granulation tissue.

Less exudate leakage, water in exudate evaporates, proteins left behind form surface layer.
