Disease Roles
Colon Lumen Overview
The colon lumen is the interior space within the colon, responsible for the final stages of digestion, including water and electrolyte absorption, feces formation, and hosting a diverse gut microbiota. It is a critical interface between the host tissue and the gut microbiome, influencing overall health and susceptibility to various gastrointestinal diseases.
