Explanation: 

Detailed explanation-1: -Capillaries: They are the smallest blood vessels found in the body of a human being. These are the smallest vessels, whose walls are one-cell thick. On reaching the tissue or organ, the artery is differentiated into smaller blood vessels, that is, capillaries that bring blood to all the cells of the body.

Detailed explanation-2: -Capillaries are the smallest blood vessels in the body. How small are they? About ten of them equal the thickness of one human hair, and most are so small that only one blood cell can pass through them at a time.

Detailed explanation-3: -Capillaries are the smallest type of blood vessel. They can be as tiny as 5 micrometers, which is less than a third of a hair’s width. A capillary wall is only one cell in thickness. The capillary wall is made of endothelial cells and allows oxygen, nutrients, and waste to pass to and from tissue cells.

Detailed explanation-4: -A third type of capillaries, sinusoidal capillaries, is discontinuous. These capillaries have even larger gaps and pores. Sinusoidal capillaries are in your liver, spleen, lymph nodes, bone marrow and endocrine glands.
