Question 1: When going from a lying to a standing position select what occurs (increase, decrease or no change) to each of the following parameters:
1. Venous return
2. Stroke volume
3. Cardiac output
4. Mean arterial pressure
Now consider and select what would be the compensatory changes in the following parameters (increase, decrease or no change):
5. Baroreceptor signalling
6. Sympathetic activity
7. Parasympathetic activity
8. Heart rate
9. Total peripheral resistance
10. Venous return
11. Stroke volume
12. Cardiac output

QUESTION 4: The following is a question that has not been discussed in detail during your lectures, try to apply the knowledge you have gained in lectures to answer the following question.
You have been to the blood bank and have given approximately a half litre of blood. What would initially occur (increase, decrease or no change) to the following parameters?
Venous return
Stroke volume
Cardiac output
Mean arterial pressure
Now, what would the compensatory changes (increase, decrease or no change) be to the following parameters?
Sympathetic activity
Heart rate
Total peripheral resistance
