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.
The blood absorbs oxygen from the lungs - enabling it to be transported throughout the body.
blood is pumped through lungs
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 from the body is first received by the heart in right artery. This blood is then pumped into the lungs so that it can get oxygen before being distributed to the rest of the body.
The two types of blood that are in the heart are oxygen-rich blood that is pumped from the lungs to the body (systemic circulation) and oxygen-poor blood that is pumped from the body to the lungs (pulmonary circulation).
To remove CO2 and to replenish the O2 in the blood.
Oxygen-rich blood moves from the lungs to the heart, where it is pumped out to the body through the arteries. It circulates through the body's tissues and organs, delivering oxygen and nutrients, before returning to the heart through the veins.
You breath in oxygen, oxygen goes to the lungs. The oxygen is carried from the lungs to the heart. The blood cells are filled with oxygen, then pumped through your body. If you feel on your neck below your jaw, you should feel your pulse. This is an artery pumping blood to your brain. Then, the used blood is pumped back to your heart to receive more oxygen and then is pumped back to somewhere in your body.
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 from the heart to the lungs for oxygenation and then circulated to the rest of the body through arteries to deliver oxygen and nutrients, returning to the heart through veins to be pumped again.
The left atrium of the heart receives blood high in oxygen from the lungs via the pulmonary veins. This oxygen-rich blood is then pumped into the left ventricle before being circulated throughout the body.
