Which organ is responsible for eliminating waste products and non-digestible material?

The large intestine plays a crucial role in the digestive system, primarily responsible for the elimination of waste products and non-digestible materials from the body. As food passes through the digestive tract, after nutrients are absorbed in the small intestine, the remaining waste matter enters the large intestine. Here, water is reabsorbed, and the indigestible parts are compacted into feces for excretion.

In contrast, the stomach is primarily involved in the mechanical and chemical digestion of food, breaking it down into a semi-fluid mixture called chyme. The esophagus serves as the conduit for food and liquids to travel from the mouth to the stomach but does not play a role in waste elimination. The pancreas, while essential for digestion by producing enzymes and hormones, also does not directly contribute to the elimination of waste but rather focuses on aiding in the digestion of food.

Overall, the large intestine's function of forming and expelling waste is essential for maintaining the body's health by ensuring that indigestible substances are efficiently removed.
