Explain the advantages of red blood cells passing through a capillary one at a time.

Answer

The advantages of red blood cells passing through a capillary one at a time include increased surface area for exchange, efficient delivery of oxygen, and a slow flow rate.

Q: What is the function of capillaries in the circulatory system? A: Capillaries are small blood vessels that connect arteries and veins. They are responsible for the exchange of oxygen, nutrients, and waste products between the blood and the tissues.
Q: Why do red blood cells pass through capillaries one at a time? A: Red blood cells are small and flexible enough to squeeze through the narrow openings of capillaries one at a time, allowing for efficient exchange of oxygen and nutrients with the surrounding tissues.
Q: What are the advantages of red blood cells passing through a capillary one at a time? A: 1. Increased surface area for exchange - by passing through capillaries one at a time, each red blood cell is able to come into close contact with the surrounding tissue, allowing for maximum exchange of oxygen and nutrients. 2. Efficient delivery of oxygen - by passing through capillaries one at a time, red blood cells are able to deliver oxygen more efficiently to the tissues that need it the most. 3. Slow flow rate - the narrow diameter of capillaries creates a slow flow rate, allowing for more time for exchange of nutrients and waste products.
