The human gut, also known as the gastrointestinal tract, is a complex system responsible for digesting food and absorbing nutrients. It begins at the mouth and extends through the esophagus, stomach, small intestine, and large intestine, ending at the rectum. The gut plays a crucial role in breaking down food, allowing the body to utilize essential vitamins and minerals. In addition to digestion, the gut houses a diverse community of microorganisms, known as the gut microbiome. This microbiome aids in digestion, supports the immune system, and contributes to overall health. A balanced gut microbiome is important for maintaining human health and preventing various diseases.
