it carrys on the same cycle over and over again
hope dis helps
After the blood returns to the lungs the blood then becomes oxygenated.
Before blood returns to the left atrium, it is collecting oxygen from the lungs. While in the lungs it is releasing carbon dioxide to be exhaled.
The blood that returns to the lungs is rich in Carbon Monoxide (CO). CO exits the blood via the lungs when it returns to the lungs, and Oxygen (C2O) will enter the blood. The blood then goes back to the heart and it gets pumped through the rest of the body.
When blood is pumped to the lungs, it releases carbon dioxide and picks up oxygen. The blood then returns to the left side of the heart, which pumps the oxygenated blood to the body tissues.
The blood vessels that carry the blood from the heart to the lungs are the pulmonary arteries. Blood returns from the body and is pumped by the right ventricle to the lungs, through the pulmonary arteries. The blood returns to the left side of the heart through the pulmonary veins.

Blood becomes oxygenated in the lungs, then the oxygenated blood goes to the heart via the pulmonary veins and enters the left atrium
Blood is bright red when it returns to the heart from the lungs. It is darker red when it returns to the right atrium from the systemic circulation.
deoxygenated blood
Blood returns to the heart via the pulmonary veins and it enters into the left atra.

Blood moving from the lungs to the heart carries oxygen. This blood returns to the left atrium via the pulmonary veins.
No. Blood from the head returns to the right side of the heart and is then pumped ino the lungs. The blood from the head returns to the heart and is then sent to the lungs. If it went to the lungs before returning to the heart, that would be wasteful becase then it would have gone through the lungs twice before going to where it was needed.
