Question

when a person develops a sore throat, white blood cells are drawn to the area of infection by a process called
multiple choice
attraction
diapedesis
chemotaxis
ameboid movement
margination

Explanation:

Chemotaxis is the movement of cells (such as white - blood cells) towards a chemical stimulus. In the case of a sore throat (an infection site), chemical signals are released that attract white - blood cells to the area of infection. Attraction is too general a term. Diapedesis is the process by which white - blood cells move out of the blood vessels into the tissues. Ameboid movement is a type of cell movement similar to that of an amoeba. Margination is the process where white - blood cells adhere to the walls of blood vessels near the site of infection before diapedesis.

Answer:

C. chemotaxis
