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: -Blood Flow Like all fluids, blood flows from a high pressure area to a region with lower pressure. Blood flows in the same direction as the decreasing pressure gradient: arteries to capillaries to veins.
Detailed explanation-3: -Blood flows through three types of blood vessels: Arteries carry oxygen-rich blood away from your heart. Capillaries are tiny, thin blood vessels that connect veins and arteries. Veins carry oxygen-poor blood from your body’s tissues back to your heart.
