The blood in veins is deoxygenated (meaning that the oxygen has already been used throughout the body and is returning to the heart, then the lungs, so that the hemoglobin can be replenished with oxygen); whereas, the arteries carry oxygenated blood throughout the body. In summary, the veins carry LESS oxygenated blood than the arteries. HOWEVER, there are two situations where this is not true. This concept is reversed in fetal circulation AND in cardiac collateral circulation; therefore, a tip is to think of blood not in terms of oxygenated or deoxygenated but rather in terms of which way the blood flows from the heart. If blood flows from the heart to the body it is carried by and artery, conversely if it blood is carried from the body back to the heart by the body's veins.
Yes, blood that flows through veins (not arteries) is rich (high) in oxygen.
The pulmonary vein transports oxygenated blood from the lungs to the heart, so yes, unlike most other veins, the blood here is indeed rich in oxygen.
Veins carry blood low in oxygen and arteries carry blood rich in oxygen.
The pulmonary vein carries oxygenated blood from the lungs to the heart. This is the only time oxygenated blood is carried by veins.
all veins except for the pulmonary veins are low in oxygen
The pulmonary veins are high in oxygen and low in carbon dioxide. All other veins are high in carbon dioxide and low in oxygen.
Usually veins carry blood low in oxygen back to the heart except for the pulmonary veins. They carry blood higher in oxygen.
Arteries always carry blood away from the heart. Veinsalways carry blood back to the heart.Most arteries are high in oxygen except for the pulmonary arteries. Most veins are low in O2.And then there are the pulmonary veins. The only veins that carry blood high in oxygen.
The blood with high oxygen content enter the heart in left atrium through right and left pulmonary veins, combined together.
Blood cells low on oxygen.
The arteries carry the blood that is high in oxygen content, while the veins carry the blood that is low in oxygen content.
Deoxygenated blood is low in oxygen and high in carbon dioxide.
Arteries take blood away from the heart (arteries=away). Almost always these carry blood high in oxygen. Veins carry blood back to the heart and almost always carry blood low in oxygen. The only exception: Pulmonary arteries carry blood away from the heart but they are low in oxygen and need to pick up this in the lungs. The Pulmonary veins carry oxygen to heart from the lungs.
A blood seems blue in veins because when a blood is in veins they are low in oxygen and therefore look blue. When they get oxygenated, they become red and are carried by the artery.
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, they usually carry low oxygen blood except for the pumonary veins which carry oxygen from the lungs to the heart.
Low oxygen/de-oxygenated blood is carried by:all the veins (except the pulmonary vein)the pulmonary artery.
