The heart is a pump that circulates the blood around the body
if blood entering the heart gets mixed with blood leaving the heart the the blood leaving the heart will get poluted. the blood entering the heart is poluted when it enters the heart, the heart cleans it up; so when the blood leaves the heart it is clean so if it gets polluted the person may get sick and this leads to his/her death.
The two blood circuits of the body are the systemic circulation, which carries oxygen-rich blood from the heart to the body tissues and back to the heart, and the pulmonary circulation, which carries oxygen-poor blood from the heart to the lungs for oxygenation and back to the heart.
It gets oxygen to it.
It gets the blood from the rest of your body blood that is pumping
The heart is a muscle and gets its nurisment from blood that flows through it. And it also pumps and circulates blood through it in large vessels and chambers.
the left side of the heart gets its blood from the lungs through the pulmonary veins. this blood is deoxygenated. hope this helped...
Your blood gets pumped better.
it gets pumped away from the heart
The heart delivers blood to itself, one half gets "fresh" blood, while the other half gets the blood that comes back after being circulated through the entire body.
Of course heart muscles need a blood supply for the cellular respiratory process as the blood carries the final electron acceptor oxygen which is key to oxidative phosphorylation in humans.
A lot of things:Congestive heart failure - blood gets backed up in your heart because your heart isn't pumping so well.Massive Blood or fluid loss - you just don't have a lot of blood/blood volume to return to the heart. Happens if you have massive hemorrhages, trauma, diarrhea, etc.Obstructive embolism - Like if a clot in your leg or something gets stuck in your lungs (a pulmonary embolism) - blood gets backed up in your lungs and can't make it back into your heart
ANSWER:The answer is very simple. Blood is the fluid that gets pumped by the heart.
