Detailed explanation-1: -A vein is a blood vessel that transports blood from all parts of the body to the heart. They carry deoxygenated blood back from the body to the heart. Pulmonary artey carries blood which is rich in carbon dioxide from the right ventricle of the heart to the lungs for oxygenation.
Detailed explanation-2: -Veins carry carbon dioxide-rich or deoxygenated blood from all parts of the body back to the heart.
Detailed explanation-3: -Yes. The blood in most veins has hemoglobin that is 75% saturated with oxygen. This is relatively unsaturated compared to the blood in arteries (which is 95-100% saturated), but there is still some oxygen. Smooth muscle tissue in the tunica media layer of the walls of the arteries.
Detailed explanation-4: -Capillaries have thin walls that allow oxygen, nutrients, carbon dioxide and waste products to pass through, to and from the tissue cells. Veins then carry the blood back to your heart, and the process begins again.
