Question

Quizplus · Accepted Answer

Plasma antibodies and white blood cells defend against pathogens. White blood cells are a crucial component of the immune system, as they work to identify and destroy foreign pathogens such as viruses and bacteria. Antibodies, which are produced by B cells, are proteins that attach to specific foreign substances in the body and label them for destruction by other components of the immune system. These antibodies are found in the plasma component of blood, along with other immune system components such as cytokines and complement proteins. Thus, blood plays a crucial role in immune function by transporting these immune system components throughout the body to identify and eliminate pathogens.
