Answer:

Capillaries

Explanation:

Capillaries are one of the three major blood vessels in humans (the other two being; veins and arteries). They are known to connect the arteries and the veins together in the circulatory system.

Macrophages are specialized cells that hunt for, engulf, and kill bacteria and other dangerous organisms. They can also activate other cells by releasing substances known as cytokines, which present antigens to T cells and start an inflammatory response.

Blood monocytes that leave the bloodstream to differentiate in various organs give rise to macrophages. Each macrophage population exhibits significant variety, which most likely reflects the level of specialization necessary for each tissue's environment.
