D)Margination of leukocytes

Question

A)Immediately after injury or infection, the damaged tissues release histamines, kinins, and prostaglandins. These substances serve as chemical mediators to dilate blood vessels, causing more blood to flow to the injured area. This increase in blood supply is called hyperemia and is responsible for the characteristic signs of redness and heat that accompany inflammation. Margination refers to the process by which leukocytes aggregate along the inner surface of blood vessels in an injured area. Exudate production occurs later in the inflammatory process and involves the release of fluid, dead cells, and cellular products from the injured area. Cellular regeneration occurs during the last stage of the inflammatory process and does not cause redness or warmth.
