The difference in resistance to blood flow in a blood vessel of radius 60μm and a capillary of radius 4μm. Introduction: The blood vessel represents one of the major components of the human circulatory system is responsible for the circulation of blood. The blood vessels are of different types such as arteries (carries blood away from the heart), veins (carries blood to the heart from the body and tissues), and more.

Expert Solution & Answer

Explanation of Solution

The size of blood vessels varies in each one of them. The aorta has the largest radius, while the capillaries are known to have the lowest radius. The narrower the blood vessel, the greater the frictional resistance to blood flow. The radius of a blood vessel is 60μm while of a capillary is 4 μm hence the difference is 15 fold (60/4) and because the resistance increases to the fourth power in inverse proportion while the difference in resistance to blood flow will be 15 to the fourth power or 15⁴ which is equal to 50,625.

The effect of parallel tubes on flow rate. A: the fluid reservoir is placed on top of the bench (Figure 4A) to give a pressure head. This is connected to the flow module by rubber tubing with a clamp on it. A 5-mL volumetric flask is used to collect fluid, and the time taken with different numbers of tubes in parallel is recorded on a stopwatch. (Figure 4B) The calculated flow rate plotted against the number of tubes. a. Interpret the graph b. What variable is the addition of more tubes in parallel affecting? c. What are the benefits to the tissue of having more blood vessels in parallel?

The effect of length on flow rate. A: the fluid reservoir is placed on top of the bench (Figure 2A) to give a pressure head. This is connected to the flow module by rubber tubing with a clamp on it. A 5-mL volumetric flask is used to collect fluid, and the time taken with different lengths of tubes is recorded on a stopwatch. (Figure 2B) The calculated flow rate plotted against the length of tube. a. Interpret the graph/data b. Would you expect the length of blood vessels to change in the body as a means of controlling flow? Comment on your answer. c. Is this likely to be a common mechanism for controlling blood flow to different tissues?
