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.
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.
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.

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.
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.
Cardiac volume is the blood pumped in a single contraction
