Title: PhysioEx 9.0 Exercise 5, Activity 7. Post by: lilrooskin on Mar 26, 2012 Can someone help, I am not understand this last activity very well.
1.) Explain how the heart could compensate for peripheral resistance. 2.) Which mechanism had the greatest compensatory effect? 3.) Explain what happened when the pump pressure and beaker pressure were the same 4.) Explain whether it would be better to adjust heart rate or blood vessel diameter to achieve blood flow changes at a local level. (example: the digestive system.) It would be so awesome if somebody could help explain this to me. Thank you! Title: Re: PhysioEx 9.0 Exercise 5, Activity 7. Post by: madison.holley1 on Mar 26, 2012 1.) Explain how the heart could compensate for peripheral resistance. The heart can compensate for changes in peripheral resistance by increasing contractility. 2.) Which mechanism had the greatest compensatory effect? Decreasing the pressure in the right-most beaker (the destination beaker) had the greatest effect because this decreases afterload.

If you adjust the heart, that affects the ENTIRE circulatory system which may be problematic. |
