The document discusses inflammation and repair. Inflammation is the local response to any insult that acts to eliminate the agent and damaged tissues. Repair is the body's response to restore normal structure and function. Both occur together with some overlap. Acute inflammation involves vascular changes, leukocyte exudation, and release of chemical mediators, while chronic inflammation is characterized by a mononuclear infiltrate. The stages of repair include inflammation, angiogenesis, granulation tissue formation, collagen deposition, and wound strengthening or contraction. Factors such as nutrition, infection, and wound characteristics influence the healing process.
