Veins carry oxygen depleted blood to the heart.
By definition, ALL arteries carry Oxygen rich blood. Veins carry oxygen depleted blood.
Arteries always carry blood to an organ/area, conversely veins always carry blood away. Interestingly Arteries can be thought to carry blood rich in oxygen, whereas veins carry oxygen depleted blood. When I was younger I remembered this as (Artery = Air), it's crude but it worked. There are 2 major vessels however that are the exception to this rule. The Pulmonary Artery, which carries oxygen depleted blood from the heart to the lungs. and the Pulmonary Vein which carries oxygen rich blood back to the heart. Happy Pumping
Except the pulmonary vein which carries oxygenated blood back to the heart. Arteries = oxygenated Vein = oxygen depleted
The pulmonary veins carries oxygen rich blood from the lungs to the heart.
Usually veins carry blood low in oxygen back to the heart except for the pulmonary veins. They carry blood higher in oxygen.
Lack of oxygen causes blood cells to appear blue. Remember that all veins except the pulmonary vein carry 'oxygen depleted blood' or deoxygenated blood. Dont worry that your veins appear blue though! Its fine.
Veins carry blood to the heart. They usually carry oxygen-poor blood.
Blood travels away from the heart through arteries and to the heart through the veins.Veins are thin walled, with valves in them and with a wide lumen (central opening, the space that blood flows).Arteries are thick, muscular walled with many different layers and with a narrow lumen.In most cases, veins carry oxygen depleted blood (blue blood) from the tissues while arteries carry oxygen rich blood (red blood) to the tissues. However, the pulmonary artery carries oxygen depleted blood from the heart to the lungs. The pulmonary veins carry oxygen rich blood to the heart from the lungs.
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.
The term "vein" describes vessels leading to the heart. The Pulmonary Veins are the only veins that carry oxygen rich blood. They carry the blood from the lungs to the heart.
Pulmonary artery is the only artery that carries non-oxygenated blood. Conversely, the pulmonary vein is the only vein that carries oxygenated blood.
Coronary veins have oxygen rich blood. Hope I helped (:no, they carry deoxygenated blood to the coronary sinus.
