Blood Vessels: Arteries: These are large blood vessels that take oxygenated blood away from the heart to be distributed throughout the body. The aorta is the body's largest artery. Veins: These blood vessels take deoxygenated blood from around the body back to the heart and lungs to be oxygenated.Capillaries: These tiny blood vessels are where the exchange of oxygen and nutrients take place. The nutrients and oxygen are exchanged for wastes that are taken from the cells.eins: These blood vessels take deoxygenated blood from around the body back to the heart and lungs to be oxygenated.
