Which of the following is the FINAL section of the large intestine?

The final section of the large intestine is the anal canal, which serves as the terminal passage for the digestive tract. It is responsible for regulating the expulsion of feces from the body. The anal canal is situated just below the rectum, making it the most distal part of the gastrointestinal system.

The colon precedes both the rectum and the anal canal and is involved in the absorption of water and salts, as well as the formation of feces. The rectum itself is the storage site for feces before they are expelled, but it concludes right before the anal canal begins. The viliform appendix, while part of the large intestine, is not a section that directly facilitates the final process of digestion or waste excretion.

Understanding the anatomy of the large intestine is critical, particularly in the context of procedures involving the gastrointestinal tract and for recognizing the functions of each section. The structure of the anal canal is essential for maintaining continence and enabling the controlled elimination of waste.
