Transportation: The cardiovascular system transports blood to almost all of the bodyâs tissues. The blood delivers essential nutrients and oxygen and removes wastes and carbon dioxide to be processed or removed from the body. Hormones are transported throughout the body via the bloodâs liquid plasma.
Arterioles feed oxygenated blood to the capillaries. The AORTA is the largest artery in the body, taking blood from the heart, branching into other arteries that send oxygenated blood to the rest of the body. CAPILLARIES. distribute the nutrients and oxygen to the body's tissues and remove deoxygenated blood and waste.They are extremely thin, the walls are only one cell thick and connect the arterioles with the venules (very small veins).lood circulates through a network of vessels throughout the body to provide individual cells with oxygen and nutrients and helps dispose of metabolic wastes. The heart pumps the blood around the blood vessels.
