Detailed explanation-1: -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. Explain that smoking harms your blood cells and blood vessels, including tiny capillaries.

Detailed explanation-2: -Why Are Capillaries Very Small in Size? Capillaries need to be small in order to facilitate oxygen and carbon dioxide gas exchange in cells. 3 They also play a role in fluid and nutrient exchange, forming the connection between the body’s smallest arteries (arterioles) and smallest veins (venules).

Detailed explanation-3: -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-4: -Capillaries, the smallest and most numerous of the blood vessels, form the connection between the vessels that carry blood away from the heart (arteries) and the vessels that return blood to the heart (veins).
