POSTERIOR AND ANTERIOR VIEW!
DEFINITION:HEART is hollow muscular organ that pump the blood through the circulatory system of rhythmic contraction and dilation.
PHYSIOLOGY;
As the heart beats or contract, the blood makes continuous round trip..in and out of the heart through the rest of the body, and then back to the heart..only to be sent out again..
>the amount of work that a heart does is almost too incredible to believe.
>In one day it pushes the body's supply of 6 quarts or so of blood through the blood vessels over 1000 times, meaning that it actually pump about 6000 quarts of blood in a single day.
●MAIN PARTS OF HEART ON ANTERIOR VIEWS;
(1) AORTA =the major systemic artery arises from the left ventricle.
>The largest artery in the body.
>Aorta begin at the top of the left ventricle, the heart's muscular pumping chamber.
>The heart pumps blood from the left ventricle into the aorta through the aortic valve.
>Three leaflets on the aortic valve open and close with each heartbeat to allow one way flood of the blood.
