Title: PhysioEx 9.0 Exercise 5 Activity 7 Cardiovascular Dynamics
Post by: blackxrs on Mar 29, 2012
Need help with Exercise 5 Activity 7 Question 4


4. Explain whether it would be better to adjust heart rate or blood vessel diameter to achieve blood flow changes at a local level (for example, in just the digestive system).

Thanks in advance

Sorry, I have not gotten to that exercise yet.  Can you provide any assistance with exercise 3?

Since only one part of the body is being affected, it would make sense to only adjust that particular system. If you adjust the
heart, that affects the ENTIRE circulatory system which may be problematic.

Changing blood vessel diameter vs. HR is much safer and clinically relevant. It is much easier to manipulate BV diameter as HR such remain in an acceptable range
