How does the digestive system maintain homeostasis? Homeostasis is the balance the body maintains to continue to function properly. All the bodily systems, including the digestive system, contribute to homeostasis. The body maintains homeostasis using both positive and negative mechanisms. Negative feedback occurs when the body senses an imbalance, and the various systems work to counterbalance and restore proper equilibrium. Positive feedback happens when the body senses a change and works to enhance it. The body's pH balance, its ratio of acid and alkaline, is an important part of overall homeostasis.
