We need our heart because it pumps blood through our body. When it does, the blood goes to all the body so every part gets all the blood that is nesessary.

∙ 12y agoThe heart is an organ like any other, so it is conformed of cells that need oxygen to live. If the cardiac cells receive no oxygen from the blood then they will die, causing a heart attack. The vessels that provide this supply are the coronary arteries
Heart is the pumping organ of human body, it needs its own blood supply cause it is resposible for pumping the blood through out the body, it receives oxiginated blood from lungs via pulmonary vein( the only vein in the human body which carries pure blood), and then pump it through Aorta(Artery) to the body.

∙ 12y agoThe heart needs these parts because it won't function without them!!!!!! So maybe if you ask your teacher she will probably say "go f**k yourself"

∙ 10y agoBecause the heart needs expansion to work with and without its part then the heart wouldnt be able to work

What are the heart's own blood vessels?
Coronary arteries supply blood to the heart itself.
How can the heart be nourished?
The heart has its' own blood supply by way of the coronary system.
Does the heart has its own supply of blood called mypcardium blood vessel?
No, but a good guess. They are called the coronaries.
Why does blood volume loss cause tachycardia?
Because the heart itself needs a blood supply in order to function. If the heart is starved of its own blood - it will stop.
Why does the heart muscle need oxygenated blood?
the heart is a muscle, and every muscle needs blood because the blood caries oxygen to the cells of that muscle which is then converted into energy and this is what makes our bodies work. your heart however is a special muscle that pumps your blood to all of the muscles in your body.
Which blood vessels supplies the heart with its own blood supply?
Re-oxygenated blood flows into the heart via the pulmonary vein. However, these blood will leave the heart, and supply oxygen to the body. The heart has its own circulation; the cardiac arteries (supply the oxygenated blood)and the cardiac veins (drain the collected venous blood).
How is the brain is kept alive by the circulatory system?
Almost none. It does control its own flow, and it will speed the heart in anticipation of need, but that does not effect the actual flow of blood.
What structure in the heart distributes blood to body organs?
The Coronary arteries carry blood to the heart so the heart has its own supply of oxygen and nutrients to perform its function.
Where would be the most dangerous part in heart to have a blood clot?
The coronary arteries because they supply fresh blood to the heart's own muscle. The heart stops pumping if its muscle wall doesn't get enough blood. The coronary arteries are what supply blood to the heart itself and they are pretty small and narrow- they can't handle even a small clot.
What are the three kinds of blood circulation?
Pulmonary circulation = between the heart and the lungs Coronary circulation = the heart tissue's own blood supply Systematic circulation = between the heart and the rest of the body
Does blood flow from the coronary arteries into the heart?
Arteries are blood vesicle that take blood away from he heart. However, the coronary arteries are arteries that take blood to the muscles of the heart and as such these specific arteries do enter the heart.
What are the three major circuits of blood flow?
Pulmonary circulation (between the heart and lungs) Systematic circulation (between the heart and the rest of the body) Coronary circulation (the heart's own blood supply/supply to cardiac tissue)
