Question

1. What is an "optimal" blood pressure (include units)? What pressure is considered high blood pressure (units)?

Normal ______

High ______

2. Given the relationship: Mean Arterial Pressure=Cardiac Output ×Peripheral Resistance

Assuming no other changes, what would happen to mean arterial pressure if:

a) HR fell?

b) Peripheral resistance increased?

3. Why does systolic pressure significantly change during exercise and recovery while diastolic pressure remains relatively constant during the same time?

4. During cycling exercise, changes in blood flow occur throughout most of the body. Identify a structure in the body that...

receive significant increases in blood flow

significant decreases in blood flow and

no changes in blood flow.

5. How does the body achieve the changes in blood flow described in question #4? Be sure to identify the specific structures and mechanisms involved.

6. Explain the underlying cause of "postural hypotension".
