Intestinal microbiota
The large intestine contains multiple types of bacteria that can break down molecules the human body cannot process alone, demonstrating a symbiotic relationship. These bacteria are responsible for gas production at host–pathogen interface, which is released as flatulence. However, the primary function of the large intestine is water absorption from digested material (regulated by the hypothalamus) and the reabsorption of sodium and nutrients.
