PATHOLOGY

Detailed explanation-1: -The arteries (red) carry oxygen and nutrients away from your heart, to your body’s tissues. The veins (blue) take oxygen-poor blood back to the heart. Arteries begin with the aorta, the large artery leaving the heart. They carry oxygen-rich blood away from the heart to all of the body’s tissues.

Detailed explanation-2: -The aorta is the largest artery in the body and carries oxygenated blood to the body.

Detailed explanation-3: -Arteries generally carry oxygenated blood to deliver oxygen to organs, and veins generally carry deoxygenated blood back to the heart for re-oxygenation. The singular exceptions are the pulmonary arteries and pulmonary veins.
