Consider how all the factors contributing to MAP impact eachother, and put the following parameters in order regardingcause and effect, starting with a reduction inblood volume (due to donating blood, for example), and movingthrough the compensatory mechanisms involved.
1. MAP is restored towards its set point
2. Heart rate, ventricular contractility, venous return, and TPRall increase
3. The sympathetic activity increases and parasympatheticactivity decreases
4. Baroreceptor activity decreases
5. MAP decreases
6. Cardiac output decreases
7. Blood volume is reduced
8. Venous return decreases
9. EDV decreases
10. Stroke volume decreases
put in order
