Answer to Question 1

The inflammatory response begins with the dilation of arterioles and capillaries at the site of injury, which increases blood flow to the affected area. The capillaries within the damaged tissue become more permeable, allowing some blood plasma to escape into the tissue and cause local edema. The various changes in blood vessels attract immune cells that can destroy foreign agents and clear cellular debris. Among the first cells to arrive are the phagocytes, which slip through gaps between the endothelial cells that form the blood vessel walls. The phagocytes engulf microorganisms and destroy them with reactive forms of oxygen and hydrolytic enzymes. When inflammation becomes chronic, these normally useful products of phagocytes can damage healthy tissue.

Answer to Question 2

D
