The correct Answer is:
To determine the diameter of capillaries for red blood cells (RBCs) to pass through, we can follow these steps: ### Step 1: Understand the Size of RBCs - Red blood cells (RBCs) are typically about 6 to 8 micrometers in diameter. This size is crucial in determining the diameter of the capillaries they need to pass through. ### Step 2: Analyze Capillary Diameter - Capillaries are the smallest blood vessels in the body, designed for the exchange of gases, nutrients, and waste products between blood and tissues. The diameter of capillaries is generally around 5 to 10 micrometers. ### Step 3: Determine the Minimum Diameter Requirement - For RBCs to pass through capillaries, the diameter of the capillaries must be less than or equal to the diameter of the RBCs. Since RBCs are about 6 to 8 micrometers, capillaries must have a diameter that can accommodate them. ### Step 4: Conclusion - The diameter of capillaries for RBCs to pass should be less than 5 micrometers. This ensures that they can pass through the narrowest sections of the capillaries, which may be slightly smaller than the RBCs themselves. ### Final Answer - The diameter of capillaries for RBCs to pass should be **less than 5 micrometers**. ---
