functions of capilary walls
Answers
Answer:
Exchange of Gases, Nutrients, and Waste Between Blood and Tissue Occurs in the Capillaries. Capillaries are tiny vessels that branch out from arterioles to form networks around body cells. In the lungs, capillaries absorb oxygen from inhaled air into the bloodstream and release carbon dioxide for exhalation.
Explanation:
Capillaries are very tiny blood vessels — so small that a single red blood cell can barely fit through them.
They help to connect your arteries and veins in addition to facilitating the exchange of certain elements between your blood and tissues.
This is why tissues that are very active, such as your muscles, liver, and kidneys, have an abundance of capillaries. Less metabolically active tissues, such as certain types of connective tissue, don’t have as many.
