Shunting of blood from inactive to active tissue b. Decreasing parasympathetic and increasing sympathetic activity to increase heart rate c. Decreasing endothelial nitric oxide production d. Changing regional blood flow in proportion to exercise intensity

Answer 1

1. All the options are an example of physical fitness. It depends on the type and duration of work.

2. Exercise increases the sympathetic activity and reduces parasympathetic activity, leading to increased contractility and increased stroke volume

.Exercise keeps your endothelial cells and blood vessels healthy by increasing your body's natural ability to produce nitric oxide. During exercise regional blood flow, including a perfusion of active muscles, is subordinate to the control of blood pressure.

So option A is false.
