The large intestine plays a crucial role in digestion by primarily absorbing water and electrolytes from the remaining indigestible food matter. This process helps to form solid waste (feces) and maintains the body’s fluid balance. Additionally, the large intestine houses a complex microflora that aids in the fermentation of residual nutrients, producing valuable substances like vitamins (e.g., vitamin K). It also plays a role in the overall regulation of gut health and immune function, as its structure and function are vital for the body’s digestive efficiency and waste elimination.
