The gastrointestinal tract is a complex system responsible for digesting food, absorbing nutrients, and expelling waste, playing a critical role in maintaining overall health. It includes a series of hollow organs joined in a long, twisting tube from the mouth to the anus, with each organ performing specific functions in digestion and nutrient absorption.

specific functions

Digestion is the complex process by which the body breaks down food into smaller components that can be absorbed and utilized for energy, growth, and cellular repair. It involves both mechanical and chemical processes that begin in the mouth and continue through the gastrointestinal tract, ending with nutrient absorption in the intestines and waste elimination.

Nutrient absorption is the process by which the digestive system breaks down food into smaller molecules that are then transported through the intestinal lining into the bloodstream to be utilized by the body. This process is crucial for maintaining cellular function, energy production, and overall health, and can be influenced by factors such as gut health, nutrient bioavailability, and the presence of certain enzymes and transporters.
