Arteries carry blood away from the heart and veins carry blood towards the heart. The vena cava brings deoxygenated blood from the body towards the heart. However, the coronary artery carries oxygenated blood to the myogenic heart muscle.
Most arteries carry oxygenated (oxygen-rich) blood from the heart to the rest of the body. Most veins carry deoxygenated (containing less oxygen and more carbon dioxide and other wastes) blood from the body tissues to the heart, which then sends that blood through the pulmonary system to be oxygenated again.o transport oxygenated blood though the system and into the veins to be oxygenated. The arteries' main functions are to carry blood (mainly erythrocytes, leukocytes, thrombocytes, and plasma) throughout the body. The blood carries oxygen, fights pathogens, clots blood, and maintains body temperature.
