Mark the following statements as true or false. If a statement is false, correct it to make a true statement.
During exercise, the parasympathetic nervous system increases the metabolic rate.

The parasympathetic nervous system is part of the autonomic nervous system responsible for promoting 'rest and digest' functions. It conserves energy by slowing the heart rate and increasing intestinal and gland activity. During exercise, this system typically decreases in activity, allowing the sympathetic nervous system to dominate.

The sympathetic nervous system prepares the body for 'fight or flight' responses during stressful situations, including exercise. It increases heart rate, dilates airways, and boosts metabolic rate to provide more energy. Understanding its role is crucial to recognizing how the body responds to physical activity.

Metabolic rate refers to the rate at which the body expends energy or burns calories. During exercise, the metabolic rate typically increases due to heightened energy demands. This concept is essential for understanding how the body adapts to physical activity and the role of different nervous system components in regulating these changes.
