Distinguish between systemic circulation and pulmonary circulation

Answer 1

Systemic circulation refers to the circulation of blood throughout the body, from the heart to various organs and tissues, and back to the heart again. This circulation delivers oxygen and nutrients to the body's cells and removes waste products and carbon dioxide from them.

Pulmonary circulation, on the other hand, refers to the circulation of blood between the heart and the lungs. This circulation delivers deoxygenated blood from the heart to the lungs for oxygenation and removes carbon dioxide from the blood. Then, it delivers oxygenated blood from the lungs back to the heart to be pumped out to the rest of the body in systemic circulation.
