The intestine is a vital organ in the human body responsible for the digestion and absorption of food. It consists of two main parts: the small intestine and the large intestine. The small intestine is where most of the nutrient absorption occurs, while the large intestine primarily functions in water absorption and waste elimination. Together, they play a crucial role in the breakdown of food, extraction of nutrients, and elimination of waste products, contributing to overall digestive health and bodily function.
