Blood vessels and their functions

Open in App

Solution

Dear Student

There are different blood vessels with different functions:

Arteries

Carry blood away from the heart

All arteries carry oxygenated blood except for the pulmonary artery

Veins

Carry blood back to the blood.

All veins carry deoxygenated blood except for the pulmonary vein.

Blood Capillaries

Carry blood from an arteriole(small artery) to a venule (small vein).

In capillaries, the blood is slowed down, giving more time for the exchange of substances like nutrients, oxygen, carbon dioxide, waste material, water, etc between the blood and the surrounding tissues.
