Which component of the blood is part of the body’s immune system?
VARVARA [1.3K]
The answer is D, white blood cells.

The main function of white blood cells is to defense the body from bacteria or other pathogens. There's 2 main kinds of white blood cells, lymphocytes and phagocytes. Lymphocytes mainly produce antibodies that can kill bacteria or any pathogens, and phagocytes can ingest the pathogens directly.

Therefore, since the white blood cells can protect our body, they're part of our immune system.
