Arteries carry blood away from the heart, while veins bring blood back to the heart, with valves preventing backflow. The heart has chambers that facilitate the flow of blood, and large veins deliver blood to the heart. Valves in the heart play a crucial role in maintaining blood flow.
Arteries carry blood away from the heart. When blood leaves through the Pulmonary artery, it heads towards the lungs for oxygenation. The vessels that carry deoxygenated blood from different parts of the body to the heart are veins.
The structure that prevents the backflow of blood are valves in the heart. The valves of the heart have three cusps. The chambers that receive blood entering from different parts of the body and lungs are the atria, while the ventricles pump blood away from the heart.
The two large veins that deliver blood into the right atrium are the superior vena cava and the inferior vena cava.
