The blood absorbs oxygen from the lungs - enabling it to be transported throughout the body.
Blood entering the left atrium is oxygenated blood coming from the lungs that is pumped throughout the rest of the body.
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.
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.
so it has oxygen to give to the rest of the body boooyeh ;)

The lungs
They carry blood back to the heart after it has been pumped out by the central vacuole.
It carries oxygenated blood from the lungs into the heart where the oxygented blood is then pumped around the rest of the body.
the un-oxygenated blood is pumped into the lungs where the oxygen is transfused out of the tiny air sacks or avioli before being pumped back to the heart and around the body
Blood entering the right atrium is full of carbon dioxide; that is, it is deoxygenated. From there it enters the right ventricle and is pumped to the lungs, where the carbon dioxide is exchanged for oxygen via the process known as respiration (simply put, breathing). The now-oxygenated blood returns to the left atrium of the heart, progresses to the left ventricle, and is pumped throughout the body before returning go the right atrium.
