Arteries and Veins Functions and Features

This video from Moomoomath and Science explains the roles of arteries and veins in the circulatory system. Arteries carry oxygen-rich blood away from the heart, except for the pulmonary artery, which carries oxygen-poor blood to the lungs. Veins return oxygen-poor blood to the heart, except for the pulmonary vein, which carries oxygen-rich blood from the lungs. The video also describes the structure of these vessels and their functions, including the presence of valves in veins and the high pressure in arteries. Capillaries connect arteries and veins, facilitating blood flow throughout the body.
