Final answer:
The digestive system provides energy, hydration, and waste removal during exercise.
Step-by-step explanation:
The digestive system plays a crucial role in supplying energy and nutrients to the body during exercise. When we exercise, our muscles require a constant supply of energy to function properly. The digestive system breaks down the carbohydrates, fats, and proteins in our food into smaller molecules, such as glucose, which can be used by the muscles for energy.
In addition to providing energy, the digestive system also helps with hydration. During exercise, we lose water through sweating. The digestive system absorbs water from the food and drink we consume, helping to prevent dehydration.
Furthermore, the digestive system assists in the removal of waste products produced during exercise. It eliminates carbon dioxide, a waste product of cellular respiration, through the lungs. The liver, which is part of the digestive system, helps detoxify and eliminate metabolic waste products from the body.
