Answer #1

Heart is a double pumping machine which pumps two types of bloods in two different directions at the same time. In mammals the right ventricle pumps deoxygenated blood through pulmonary aorta into the lungs and left ventricle pumps oxygenated blood into all parts of the body through systemic trunk and its branches.

The right auricle receives deoxygenated blood from all parts of the body through the pair of precaval veins and an unpaired postcaval vein. At the same time the left auricle expands to receive oxygenated blood from the lungs through common Pulmonary vein opening. The contractions of the heart chamber is called systole and relaxation is called diastole.

Systole is the pumping of blood outside because of the heart contraction.And diastole is the relaxation of heart after contraction.Systole occurs ventricle contracts and blood ejaculates into the aorta and pulmonary trunk.Diastole is the relaxation of the ventricles after blood leaves the chamver.
