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: -Alveoli are wrapped in tiny blood vessels called capillaries. The air you breathe in fills these air sacs with oxygen-rich air. This is where the exchange of gases occurs.
Detailed explanation-3: -Capillaries: These tiny blood vessels have thin walls. Oxygen and nutrients from the blood can move through the walls and get into organs and tissues.
