Explain why you think blood vessel radius can have a larger effect on the body than changes in blood vessel length (use the blood flow equation).

Explain the effect of increasing the right flow tube radius on the flow rate, resistance, and pump rate.

Both questions are from Physio Ex 9 - Exercise 5

The blood vessel radius varies to a power of four which is why the changes are greater than blood vessel length changes.

As the right flow tube radius is increased, blood flow increases, resistance decreases and the pump rate increases.
