Intestinal physiology is the study of the function and mechanisms of the digestive system, specifically focusing on the intestines. This field of research examines how food is broken down, absorbed, and processed by the digestive system to extract nutrients and eliminate waste. It also includes the study of the role of intestinal flora, motility, and permeability in maintaining gut health and overall well-being. Intestinal physiology research is important for understanding digestion and absorption processes, as well as for developing treatments for digestive disorders such as irritable bowel syndrome, inflammatory bowel disease, and celiac disease.
