Detailed explanation-1: -Capillaries are the smallest blood vessels in the body.
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.
