Gastrointestinal Physiology

Gastrointestinal physiology explores the functions of the gastrointestinal tract - the organ system responsible for digestion and absorption of food and liquid. It looks at how hormones, nerves and the muscular walls of the GI tract work together to break down and transport food, drink, and waste. Understanding how the gastrointestinal system works is essential for understanding the overall health of a person, as it plays a key role in providing the body with the necessary nutrients and fluids to stay healthy. Common disorders related to gastrointestinal physiology include indigestion, heartburn, irritable bowel syndrome, and ulcers. Treatments are available to help those suffering from gastrointestinal problems, including lifestyle changes, dietary restrictions, and medications.
