It's a circle, thus there is no first in the long run ...
but as the blood 'pools' in the ventricles during each heart beat,
then "first flow" is either within the ventricles OR through the main arteries
(aortic and pulmonary).
Your heart is responsible for keeping your blood flowing. It acts like a pump. The right side receives blood from the body where it is pumped to the lungs and the left side pumps the oxygenated blood out to your entire body. The valves of your heart keep it flowing in one direction.
it keeps blood flowing
Blood flowing throughout the body.
Plasma helps stop blood from flowing out of your body when you have a cut.
The blood was like a river flowing steadily through the body.
When the blood is flowing back to the heart, the blood has already given off its oxygen to the rest of the body which means it contain less oxygen concentration in the blood. and when blood is flowing from the heart to the rest of the body, the blood contains high level of oxygen because they were being given oxygen by the lungs which passes along the heart and the heart pumps it to the rest of the body.
2 of these valves (one on each side) stop blood from flowing back into the atria chambers of the heart when the heart is contracting and expelling blood. The other two are there to stop blood flowing out of the ventricles when the heart is filling up with blood. One stops blood flowing through the aorta to supply the body and the other stops it flowing through the pulmonary artery to the lungs.
They help because they keep the blood flowing properly around the body:)
a blood vessels transport blood to all parts of the body
The purpose of blood flowing through the body is to deliver oxygen and nutrients to cells, remove waste products, transport hormones, and regulate body temperature. Blood also helps fight infection and clot to prevent excessive bleeding.
the hearts process is to keep the blood flowing through out your whole body
it keeps your blood pressure flowing in your body so you don't die. Aside from This, the blood vessels are also the pathway of the blood towards the important organs of the body, this responsible for the ultimate functioning of the organs. Without them, the body organs will not be able to receive blood that oxygenates them.
