can someone please give answers?
Activity 8
Let’s declare the value you just obtained to be the “normal” flow rate for the purpose of this exercise.
Now decrease the right flow tube radius to 2.5 mm, and run another trial. How does this flow rate compare with “normal”?
Leave the right flow tube radius at 2.5 mm radius, and try to adjust one or more other conditions to return flow to “normal.”
Think logically about what condition(s) might compensate for a decrease in flow tube radius. How were you able to accomplish this? (Hint: There are several ways.)
Circle the correct term within the parentheses: Decreasing the right flow tube radius is similar to a partial (leakage / blockage) of the aortic valve or (increased / decreased) resistance in the arterial system.
Explain how the human heart might compensate for such a condition.
To increase (or decrease) blood flow to only one particular body system (e.g., digestive), would it be better to adjust heart rate or blood vessel diameter? Explain.
Complete the following statements by circling the correct response. (If necessary, use the pump simulation to help you with your answers.)
a. If we decreased overall peripheral resistance in the human body (as in an athlete), the heart would need to generate (more / less) pressure to deliver an adequate amount of blood flow, and arterial pressure would be (higher / lower).
b. If the diameter of the arteries of the body were partly filled with fatty deposits, the heart would need to generate (more / less) force to maintain blood flow, and pressure in the arterial system would be (higher / lower) than normal.
