How many times does blood travel through the heart?

Answer 1

ANSWER:It actually goes through more than that, but I believe you are asking why it goes to the heart twice before it gets sent to the rest of the body. The reason is the heart has no oxygen production capabilities. It therefore receives the unoxygenated blood from the body in the Superior vena cava and into the right atrium, from there it goes to the right ventricle where it is sent to the lungs to be oxgenated through the pulmonary artery. Oxygen is picked up by the blood cells in the lungs and returns back to the heart through the pulmonary vein into the left atrium. This is the second time it enters into the heart. From the left atrium it flows into the left ventricle and then exits into the aorta to the oxygenate the rest of the body.

Answer 2

Blood comes back to the heart to be pumped to the lungs to get oxygen then back to the heart so that it can go into arteries that lead to specific parts of the body.

I am 12 years old and i know that

Answer 3

It pumps it millions of times over your lifetime. Unless your life is very short, in which case it's because you have died after your blood has been pumped twice, in which case you can't read this answer because you are dead.

Answer 4

Because each half represents a different thing , The left side pumps oxygen and the right side pumps carbon dioxide.

because blood in our body is purified by only through heart

Answer 6

your heart beats twice because one beat is taking the blood in and the other is releasing it.
