प्रश्न
What does the term “double circulation” mean?
Advertisements
उत्तर
Blood flows twice in the heart before it completes one full round. The full round thus includes
pulmonary and systemic circulation. In pulmonary circulation, blood enters the lungs through
pulmonary arteries. Pulmonary veins collect the blood from the lungs and carry it back to the
left atrium.
In systemic circulation, blood from the left ventricle enters the aorta through which the blood is
sent to the body parts. From the body parts blood is collected by veins and sent back to the heart.
Therefore, the blood circulation in the human body is called double circulation.
