Phagocytosis would enable a white blood cell to ingest a bacterium

Phagocytosis is a special form of endocytosis by which cells ingest solid substances including microbial pathogens to produce an internal compartment known as a phagosome. Cells that undergo this process are called phagocytes. The white bold cells of the immune system protect the body against invasion by pathogens such as bacteria. They perform this function by phagocytosis.

<h2>Answer is option "b"</h2>

Explanation:

Our body contains miles of arteries and arterioles, yet these structures are nothing more than the vascular highways that provide a pathway for the blood. It's only when our blood reaches the tiny capillaries that nutrients and wastes can be exchanged. Capillaries are microscopic blood vessels that connect the arterioles with the venules. We'll discuss venules later in the lesson.
Capillaries are grouped together in capillary beds, which are simply a network of capillaries. Capillary beds are too small to see, but if you could see them, they would look like endless alleyways leading to virtually every tissue in our body. The rate of blood flow within a capillary bed is slow because there are so many different alleyways through which blood can travel. This slow speed limit, along with the very thin walls of the capillaries, means that capillary beds are an ideal place for the exchange of gases, nutrients, hormones, and wastes between the blood and tissue cells.
Hence, the right answer is option b "two capillary beds".
