Which organ is involved in the process of removing water from undigested food?

The large intestine, also known as the colon, plays a crucial role in the digestive system, particularly in the removal of water from undigested food. As food passes through the digestive tract, it reaches the large intestine after moving through the small intestine. By the time it reaches the large intestine, most of the nutrients and some water have already been absorbed in the small intestine.

The primary function of the large intestine is to absorb the remaining water and electrolytes from the indigestible food matter, turning it into solid waste, or feces. This process helps maintain the body's hydration levels and ensures that essential nutrients are not lost with waste. Overall, the large intestine's ability to effectively absorb water is key to preventing dehydration and promoting overall metabolic health.
