Question

Quizplus · Accepted Answer

Specific defenses involve the activities of lymphocytes, which include B-lymphocytes that produce antibodies and T-lymphocytes that directly attack infected or abnormal cells. Monocytes, leukocytes, and agranulocytes are all types of white blood cells that play a role in the immune response, but they are not specific defenses. Erythrocytes are red blood cells that transport oxygen and carbon dioxide and do not have a role in the immune response.
