What is the function of our heart???
The function of the heart is to propel, pump and supply blood which contain oxygen and nutrients to all of the cell in the body.
Firstly, to understand how our heart function look at this anatomy of the heart below
From the picture we can see that heart can be divided into 4 structure which is right atrium, right ventricle, left atrium and left ventricle.
Blood from the body through the superior vena cava and inferior vena cava to enter the right atrium with deoxygenated blood.
Then, the blood enter the right ventricle through tricuspid valve.
Next, the deoxygenated blood enter the lungs through pulmonary valve.
The deoxygenated blood change into oxygenated blood in the lungs.
Through pulmonary vein, the oxygenated blood enter the left atrium and then enter the left ventricle through bicuspid valve.
A oxygenated blood through the aorta valve to allow it be sending to the brain and throughout the entire body.
That is how the entire body get the oxygen and nutrients for the use of cell and tissue in the body to make energy and functional well.
noted : mitral valve = bicuspid valve
