MEDICAL PHYSIOLOGY

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: -In the systemic circulation, the left ventricle pumps oxygen-rich blood into the main artery (aorta). The blood travels from the main artery to larger and smaller arteries and into the capillary network.
