In the alveolar/capillary level in the lungs and in the cellular/capillary level in the other parts of the body. The cells take in oxygen from the arteries/capillaries and give out carbon dioxide. The carbon dioxide goes in veins, which take the de-oxygenated blood back to the heart, and after, it goes into the lungs, to be oxygenated again in the alveoli by oxygen that is breathed in. That goes into the heart, and the heart pumps it into the body, to be used up.
Both. In the systemic system arteries carry oxygenated blood and veins carry deoxygenated blood. The opposite is true for the pulmonary circuit.
Lungs
It comes from the 4 pulmonary veins that drain into the left atrium. they carry oxygenated blood that has come from the pulmonary circulation as well as the deoxygenated blood from the bronchial arteries.
The right atrium receives deoxygenated blood, then the blood moves into the right ventricle. So both of them receive deoxygenated blood. Once the blood returns from the lungs it is oxygenated and comes into the heart through the pulmonary veins into the left atrium then to the left ventricle then out to the body.
Oxygenated blood is necessary to provide the oxygen for metabolism in living tissue.
Oxygenated
deoxygenated
Oxygenated
Yes capillaries carry oxygenated blood :D
Both. In the systemic system arteries carry oxygenated blood and veins carry deoxygenated blood. The opposite is true for the pulmonary circuit.
the oxygenated and deoxygenated blood would mix.
The pulmonary artery carries oxygenated blood. You can remember this easily because all ARTERIES carry oxygenated blood and all VIENS carry deoxygenated blood.
Oxygenated blood is bright red; deoxygenated blood is dark red.
Amphibians
The structure in the heart that separates oxygenated blood from deoxygenated blood is the atria. These are the two sides of the heart and are separated by the interatrial septum.
Deoxygenated With the exception of the pulmonary vessels, veins carry deoxygenated blood; arteries carry oxygenated blood.
Both. The right atrium receives deoxygenated blood from the veins of the body; the left atrium receives oxygenated blood from the pulmonary vein.
