Solution

During exercise our muscles need more oxygen, hence cardiovascular changes occurs accordingly.

1. Blood flow to brain: increases

2. Parasympathetic output to heart: decrease

3. Blood flow to heart and skeletal muscle: increases

4. Mean arterial pressure: decreases

5. Cardiac output: increases

6. Blood flow to viscera: decreases

7. Radius of arterioles in abdominal organ and kidney: decrease

8. Total peripheral resistance: decreases

9. Stroke volume: increases

10. Heart rate: increases

11: Pulse pressure: increases

12. Blood flow to skin: decreases
