Blood is the conduit for oxygen around the human body. If the blood did not circulate through the lungs, oxygen could not be carried around the body. Added to that, decreasing the amount of carbon dioxide is also an essential function of the lungs; the deoxygenised blood needs to relieve itself of the carbon dioxide and collect the oxygen again. The carbon dioxide is then breathed out via the lungs.
blood is pumped through lungs
it is pumped to the heart first then to the lungs
To remove CO2 and to replenish the O2 in the blood.
Arteries.
Blood is de-oxygenated when it it pumped into the lungs, and after going through the lungs, is now oxygenated.
The blood absorbs oxygen from the lungs - enabling it to be transported throughout the body.
After passing through the lungs, oxygenated blood travels back to the heart and is pumped out to the rest of the body through the arteries.
The lungs
No. Blood from the head returns to the right side of the heart and is then pumped ino the lungs. The blood from the head returns to the heart and is then sent to the lungs. If it went to the lungs before returning to the heart, that would be wasteful becase then it would have gone through the lungs twice before going to where it was needed.
Blood is pumped to the lungs first so that carbon dioxide can be released and oxygen can be picked up. This process allows the blood to be oxygenated before it is pumped to the rest of the body to deliver oxygen and nutrients to tissues and organs.
Right ventricle. Blood gets pumped from the body to the lungs where it is oxygenated then returns to the heart where it is pumped to the the other organs that need oxygen, e.g. the brain.
