Heart - (Jan/09/2007 )
Do veins carry deoxygenatd blood which is filled with CO2? I think some part of veins carry deoxygenated blood to the right atrium. But the heart is pumped by left ventricle, right? so there must be some blood go into the left ventricle to let it work? So then the blood in the right ventricle goes into pulmonary arteries, then lungs, and then pulmonary veins carries oxygenated blood into left atirum -->left ventricle ?
Hope you can help me!
veins are going to the heart, carry deoxygenated blood from the organism to the heart and oxygenated blood from lungs to heart.
arteries deliver blood from heart to the organism, oxygenated blood to all organs but the lung (deoxygenated).
the right ventricule receive the deoxygenated blood from the whole organism, and distribute deoxygenated blood to the lung, the left ventricule receive the oxygenated from lungs, and distribute it to the whole organism.
