Do arteries carry oxygenated blood back to the heart?

Answer 1

The heart is broken up into left and right halves. The left side (when looking at it from the front as if an observer) pumps unoxygenated blood through the capillaries of the lungs where it becomes oxygenated and then back around to the right side of the heart. This is called pulmonary circulation. The right side of the heart then pumps the oxygenated blood to all the various tissues of the body. Here the tissues take in the oxygen and the now deoxygenated blood is brought back to the left side of the heart to begin the cycle again. This portion of the cycle is called systemic sirculation. In both cases. The arteries are the high pressure blood vessels that carry the blood from the heart to its ultimate destination. The lungs in the pulmonary circulation and the different body tissues in the systemic circulation. The veins then carry the blood back to the heart. Therefore arteries cannot be classified as oxygenated or unoxygenated because the arteries of pulmonary circulation are unoxygenated while the arteries of the systemic circulation are oxygenated. Arteries instead are classified as high pressure blood vessels flowing AWAY from the heart while veins pump blood back towards the heart.

Answer 2

1) Arteries that lead from the heart to the lungs carry deoxygenated blood to the lungs.
2) Veins that lead from the lungs to the heart carry oxygenated blood to the heart.
3) Arteries that lead from the heart to the body carry oxygenated blood to the body.
4) Veins that lead from the body to the heart carry deoxygenated blood to the heart.
