What is "colon"?

The colon, also known as the large intestine, is a vital part of the human digestive system. It is a long, hollow tube-like organ located in the abdominal cavity. The primary function of the colon is to absorb water, electrolytes, and nutrients from digested food and eliminate waste material from the body. It plays a crucial role in the final stages of digestion and the formation of feces. The colon consists of several segments, including the ascending colon, transverse colon, descending colon, and sigmoid colon, which collectively aid in the process of food digestion and waste elimination.
