What is a gut?

A gut is the digestive tract or the system of organs in animals and humans that processes food, absorbs nutrients, and removes waste. In simple words, the gut is the food canal that runs from the mouth to the anus. The gut includes important parts like the mouth, esophagus, stomach, intestines, and anus. In humans, the gut also has millions of useful bacteria called gut microbiota that help in digestion and immunity.

Functions of Gut

• Breaks down food into simpler forms.
• Absorbs nutrients like carbohydrates, proteins, fats, vitamins, and minerals.
• Removes undigested food as waste.
• Hosts helpful bacteria that support health.

Thus, the gut is one of the most important systems for survival and good health.
