Worth 16 points! if answered i will answer one of your questions and make you brainlist describe the flow of blood in the human body, including through each of the four chambers in the heart. explain how the blood changes as it moves through various locations in the body.

You might want to consider looking up your question word for word. I got a good result from Google that you could play off of. This is what it said:

Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium of the heart. As the ventricle contracts, blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs where it is oxygenated.

Right now, I'm unable to write something myself, but later if you still need it answered, I'll see what I can do.

loses consciousness is your real and smarter answer.

so what is your question?
