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)
They circulate and oxygenate the blood.
Then your lungs can't provide oxygen or nutrients to the blood that the heart pumps out to other parts of the body.
The pulmonary part of the heart is responsible for pumping blood to the lungs to pick up oxygen and release carbon dioxide. It consists of the right atrium and right ventricle, which work together to circulate blood to the lungs for oxygenation. Once oxygenated, the blood returns to the left side of the heart to be pumped to the rest of the body.
it needs to
circulate blood
how does the blood circulate Put simply the heart is a pump, I don't know much more about it than that.
It takes about 1 minute for the heart to circulate blood through the entire body.
The flow of blood from the heart to the lungs and back to the heart is called the pulmonary circulation.The blood flowing from the heart to the lungs would be deoxygenated and blood flowing towards the heart from the lungs would be oxygenated.
The pulmonary artery carries blood from the heart to the lungs
CPR involves compressing the heart (by compressing the chest) forcing the heart to pump blood when it is not beating. AR- artifical respiration- only pushes air into the lungs. It does not circulate oxygenated blood in the body.
heart contractions
Blood circulates in your body in a closed loop system. It is pumped by the heart through arteries to the rest of the body, then returns to the heart through veins. This process allows nutrients and oxygen to be delivered to cells while waste products are removed.
