your semi lunar valves stop slop from entering your left aorta and your lunar valves stop crud from entering your right ventricle. this is the purpose of your valves. but this is different in dogs as your septum helps fight against testicular torsion.

How does veins carry oxygenated blood while others carry deoxygenated blood?

Veins carry deoxygenated blood back to the right atrium of the heart, which sends it through the tricuspid valve to the right ventricle to the pulmonary semilunar valve to the pulmonary arteries to the lungs (to become oxygenated and get rid of waste gases) to the pulmonary veins to the left atrium of the heart through the bicuspid valve to the left ventricle through the semilunar aortic valve to the ascending aorta to the aortic arch and out to the body. So the only veins that are oxygenated are the pulmonary veins that carry the oxygenated blood from the lungs to the left atrium of the heart. They are still called veins because they carry blood TO the heart. Thus, the only deoxygenated blood in arteries is also the pulmonary arteries, because they carry the deoxygenated blood AWAY from the heart to the lungs. All veins must carry blood toward the heart and all arteries must carry blood away from the heart.

What Function Does The Heart Serve?

The heart PUMPS BLOOD through the arteries throughout your body. Veins take blood to your heart, arteries take blood away. some people think the heart pumps blood into your veins but that is NOT true. Your veins take the blood to your heart, the arteries take the blood away from your heart.
