$\Large\mathcal\pink{DOUBLE \: CIRCULATION}$

Deoxygenated blood from the body tissues is poured into right atrium. Contraction of heart forces it into right ventricle. From right ventricle deoxygenated blood flows to the lungs through pulmonary artery.oxygenated blood from lungs is return into left atrium and then into left ventricle. The left ventricle forces the oxygenated blood to the whole body.thus, for making one complete round of circulation circuit around all body parts, the blood passes through the heart twice.

the pathway of blood from heart to the lungs and back to the heart is called pulmonary circulationand the pathway of blood from heart to the body and back to hurt is called system circulation this is known as double circulation of blood
