PATHOLOGY

Detailed explanation-1: -The aorta (the main artery in your body) carries the blood from the left side of your heart to the rest of your body through many branches of arteries. Capillaries have thin walls that allow oxygen, nutrients, carbon dioxide and waste products to pass through, to and from the tissue cells.

Detailed explanation-2: -Arteries and veins link your heart to the rest of the circulatory system. Veins bring blood to your heart. Arteries take blood away from your heart. Your heart valves help control the direction the blood flows.
