👉 Oxygastric is a digestive system in mammals that includes the stomach, small intestine, and large intestine, which are interconnected by a network of tubes called villi. This system is responsible for absorbing nutrients from food into the bloodstream, where they can be absorbed further into the body through the colon. Oxygastric function plays a crucial role in maintaining homeostasis by regulating blood sugar levels, digestive enzymes production, and nutrient absorption.
