👉 Dorsal gastrointestinal, also known as the rectum or colon, is a long, muscular tube that runs from the small intestine to the anus. It plays a crucial role in digestion and waste elimination by filtering food through the walls of the digestive tract, which includes the mouth, esophagus, stomach, and large intestine. The term "dorsal" refers to its position along the gastrointestinal tract, with the colon running from the rectum down to the anus.
