Because the blood flows through tiny capillaries that are touching the air sacs in the lungs. The red blood cells release carbon dioxide. The carbon dioxide enters the air in the lungs and is exhaled. They the red blood cells take oxygen from air you breath in and then the oxygen-rich blood cells go back to the left side of the heart.

∙ 14y agoWhen blood circulates through the lungs gas exchange occurs. This causes the oxygen poor blood to be turned into oxygen rich blood. Oxygen is vital to survival so it is highly important that red blood cells are being re-oxygenated.

Why is it so important for blood to circulate through the lungs?
Because you need to do so to survive. Without blood circulating through the lungs, it would not be able to distribute oxygen to areas like muscle groups or the brain, and the body would quickly die.
What do the lungs and heart do?
They circulate and oxygenate the blood.
Why does blood circulate from the heart to the lungs?
The oxygen poor blood (not enough oxygen) goes to the lungs to get more oxygen to turn into oxygen rich blood (has plenty of oxygen)
How does 02 Rich blood circulate?
Lungs, right atrium, right ventricle, capillaries.
What direction does the blood circulate in your body?
Blood only travels one way. Away from the heart to the body and lungs and back from the body and the lungs to the heart.
What is the Most important facts about the right ventricle?
It pumps blood through the lungs.
Why does blood from the body need to be pumped through the lungs before it is pumped back to the 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.
How does circulate in the body?
Oxygen circulates through the body in blood. A molecule of oxygen (O2) from the lungs binds loosely to a molecule of hemoglobin in a red blood cell. The red blood cell travels through the capillaries and the oxygen molecule is released from the hemoglobin and is delivered to the cells.
What gas enters the blood through the lungs?
oxigen is the gas that enters the blood through the lungs
How does the blood circulate between your lungs and heart?
First the impure blood from all the body parts reach the right auricle and then into right ventricle.From right ventricle it is carried to lungs through PULMONARY ARTERY.In lungs,it gets purified[alveoli do the purification] and then it is sended to left auricle through PULMONARY VEIN.From left auricle it flows into left ventricle and then to all the body parts through systemic aorta.

Why is it important for blood to transport oxygen through your system?
You need oxygen in your lungs in order to breathe. Without blood to transport it your lungs would have none and you wouldn't be able to breathe.
