Explanation:
Detailed explanation-1: -Capillaries are the simplest blood vessels. They are the smallest of the body’s blood vessels. The major function of capillaries is the exchange of gases and nutrients between blood and tissues.
Detailed explanation-2: -Capillaries are exchange vessels. Gases (oxygen and carbon dioxide), nutrients, and wastes pass in both directions across capillary walls. Blood flow in capillaries is pushed by the pumping of the heart. Since water gets though cell membranes easily, the circulating blood moves water through every cell of the body.
