What is the primary function of the large intestine in the human body?

The primary function of the large intestine, also known as the colon, is to absorb water from the indigestible food matter that passes through it. As materials move through the large intestine, the body extracts water and salts, which helps maintain hydration and electrolyte balance. This process also compacts the remaining waste into stool for elimination.

While the small intestine is primarily responsible for nutrient absorption, the large intestine focuses on water absorption, contributing significantly to the body’s overall fluid balance and preventing dehydration. The production of bile and the breakdown of fats occur in the liver and the small intestine, respectively, highlighting the specific role of the large intestine in the digestive system.
