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.

Does blood travel up or down?

Blood must flow upward throughout your body to make it back to the heart – working against gravity. Your calf and leg muscles help push that blood upward, while valves (small flaps located inside the vein), open up and allow blood to pass through. Valves close as blood passes through to keep it from flowing back down.
