How does the excretory system and digestive system work together to maintain homeostasis?

The excretory and digestive systems work together to maintain homeostasis by managing waste and nutrient balance in the body. The digestive system breaks down food, absorbs nutrients, and produces waste, while the excretory system filters blood to remove waste products and excess substances, such as water and salts. By regulating the levels of nutrients and waste, these systems ensure that the body maintains a stable internal environment, which is crucial for overall health and functioning. Additionally, the excretory system helps to control hydration and electrolyte balance, further supporting homeostasis.
