Veins carry blood back to the heart. In contrast, arteries carry blood away from the heart.
The heart pumps it. When your heart beats it squeezes blood in the heart into the arteries and from the arteries to the veins and from the veins back into the heart.
Veins carry deoxygenated blood back the heart.
Blood flows away from the heart in arteries, and towards the heart in veins.
Veins are thin. They carry blood to the heart and brain.
Arteries drain (pump blood) into veins. Veins drain into your lungs and heart to be re-oxygenated. (This is not true for veins and arteries to and from your lungs.)
Veins
veins, maybe
Veins. Veins carry unoxygenated blood towards the heart.
Veins are blood vessels that carry blood toward the heart.
The heart chambers are not called arteries and veins. Heart chambers are atria and ventricles.
Arteries carry blood away from the heart. Veins return blood to the heart.
No. The heart is one organ in itself. Veins and arteries are just vessels that transport blood to and from the heart. To be specific, the veins transport the blood towards the heart, and arteries transport it away.
