Veins are tubes that carry blood back to the heart. This blood is usually deoxygenated, but in the case of the pulmonary vein, the blood is oxygen-rich.
These tubes (along with the heart) are known as the circulatory system, and they come in three varieties: arteries, veins, and capillaries. Arteries carry blood away from the heart, veins carry blood back to the heart, and capillaries are smaller diameter tubes connecting arteries and veins, through which blood interacts with tissues of the body.
Arteries carry oxygen-rich blood away from the heart. Next, it goes to capillaries, to deliver oxygen and nutrients to the cells. Since it is then oxygen-depleted, the blood must go back to the heart and lungs. Those tubes are called veins.
No, from the heart. The veins carry the blood back to the heart.
Veins carry blood back to the heart.
Veins carry the blood back to the heart from the body. Arteries carry blood from the heart to the rest of the body.

The tubes of the cardiovascular system are the following:Arteries - carry blood away from the heartCapillaries - allow diffusion of the dissolved substances in the plasmaVeins - carry blood towards the heart
No. Arteries carry blood AWAY from the heart and to the organs. Veins carry blood back to the heart.
The pulmonary veins carry blood from the lungs back to the heart.
Arteries carry oxygenrich blood away from the heart, and veins carry oxygen depleted blood towards the heart. The aorta carries oxygen away from the heart to parts of the body. Hope this helps!
These are called the pulmonary veins. Arteries always carry blood away from the heart but not all of these have blood high in oxygen. Veins carry blood back to the heart. Again most are low in oxygen except the ones coming from the lungs.
No, veins carry deoxygenated blood back to the heart... Coronary vessels carry blood IN the heart.
