it circulates through the body after the the muscles contract
the heart pumps to the brain to keep it going
The heart is a pump that moves all blood in the body.
There is a valve in the middle of the heart that keeps the blood going where it is supposed to go. There are also valves in the veins, but that's a different story.
Pulmonary arteries transport dehydrogenated blood from the heart to the lungs. Arteries always go away from the heart. Arteries have thicker wall to handle to pressure of the heart during the contractions. Pulmonary veins transport oxygenated blood from the lungs to the heart, which then pumps to the rest of the body.
Arteries carry blood away from the heart, veins carry blood to the heart
They travel upwards to the heart to get more carbon dioxide then they go down again.. I think.
whe blood go's through the heart it get oxganated
neither actually,they are the smallest blood vessels in the body which allow the blood to reach the tissues,and also carry the blood back to the venules,which go to the veins which carry the blood back to the heart
The blood forms in a round circle around the heart and then it goes into cells.
When your blood comes back to your heart it goes into the right atrium.
The heart. The heart.
