blood is pumped through lungs
To remove CO2 and to replenish the O2 in the blood.
The blood absorbs oxygen from the lungs - enabling it to be transported throughout the body.
The lungs
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.
When blood is pumped into the thin-walled blood vessels of the lungs, carbon dioxide is replaced with oxygen.
Lungs
Because it has to be pumped into the ventricles with some pressure so they can fill up with blood before getting pumped out of the heart and into the lungs and the body.
When blood is pumped into the thin-walled blood vessels of the lungs, carbon dioxide is replaced with oxygen.
