FAQs on Double Circulation Video Lecture - NEET
| 1. What is double circulation? |  |
Ans. Double circulation is a process by which blood is pumped twice through the heart to ensure efficient oxygenation of the blood. It involves two separate circuits: the pulmonary circulation and the systemic circulation.
| 2. How does double circulation work? | |
Ans. Double circulation works by pumping oxygen-poor blood from the body to the lungs through the pulmonary circulation. In the lungs, oxygen is exchanged for carbon dioxide, and oxygen-rich blood is returned to the heart. The heart then pumps this oxygen-rich blood to the rest of the body through the systemic circulation.
| 3. What is the significance of double circulation? | |
Ans. Double circulation is significant because it allows for efficient transfer of oxygen to the body's tissues. The separate circuits of double circulation ensure that oxygen-rich blood is delivered directly to the tissues that require it, while oxygen-poor blood is efficiently transported to the lungs for oxygenation.
| 4. How does double circulation differ from single circulation? | |
Ans. Double circulation differs from single circulation in the number of circuits involved. In single circulation, blood is pumped only once through the heart, traveling from the heart to the gills or lungs and then back to the heart. Double circulation, on the other hand, involves two separate circuits, allowing for more efficient oxygenation and distribution of blood.
| 5. What are the advantages of double circulation in humans? | |
Ans. Double circulation offers several advantages in humans. It ensures that oxygen-rich blood is continuously supplied to the tissues, allowing for sustained aerobic respiration. It also allows for effective regulation of blood pressure, as the two circuits can be adjusted independently to meet the body's demands. Additionally, double circulation enables the separation of oxygen-rich and oxygen-poor blood, preventing mixing and ensuring efficient gas exchange.
