Question

Quizplus · Accepted Answer

The term describing the attraction of leukocytes (also called white blood cells) to the site of inflammation is chemotaxis. This is the movement of cells in response to a concentration gradient of a particular chemical, typically a cytokine or chemokine. In this case, the chemicals are released by damaged tissues and attract immune cells to the area to help fight infection or promote healing. Parasitism and infection are terms related to pathogens invading the body, while phototaxis and exotaxis refer to an organism's movement in response to light or external stimuli, respectively, and are not applicable to leukocyte migration.
