What is the impact of physical activity on the digestive and excretory systems?

The chosen answer highlights a significant effect of physical activity on the body’s ability to remove waste. Engaging in physical activity stimulates various systems in the body, including the digestive and excretory systems. When a person exercises, the increased heart rate and enhanced circulation help transport nutrients more effectively and promote the efficient removal of waste products.

Physical activity can aid in the movement of food through the digestive tract by increasing intestinal motility, which helps prevent constipation and encourages regular bowel movements. Moreover, exercise stimulates the kidneys and urinary system, enhancing their ability to filter blood and excrete waste products through urine more efficiently. As a result, individuals who engage in regular physical activity may experience a quicker waste clearance process.

Other options don't directly relate to the question of how physical activity specifically impacts the digestive and excretory systems. While regulating oxygen inhalation and body temperature are important aspects of overall physical health, they do not specifically address how physical activity influences the processes of digestion and excretion. Similarly, converting food to energy is more about metabolic processes rather than the direct impact of physical activity on waste elimination.
