Explain the process of blood circulation in the body with the help of a schematic diagram.
Answer
For completing one round of circulation in the body, the blood passes twice through the heart. This is called double circulation. Double circulation involves two processes: pulmonary circulation and systemic circulation.
Pulmonary circulation — The circulation of blood between the heart and lungs is called pulmonary circulation. From the right auricle, the blood flows into the right ventricle and then to the lungs through the pulmonary arteries. The oxygenated or pure blood from the lungs is brought to the left auricle by the pulmonary veins.
Systemic circulation — The circulation of blood between the heart and other body organs is called systemic circulation. From the left auricle, the oxygenated blood flows into the left ventricle and from there it is pumped into the aorta, the largest artery in the body. The aorta divides further to supply blood to all body tissues.
