What parts does the large intestine include?

The large intestine includes the cecum and appendix, as well as the colon, rectum, and anal canal. Therefore, in daily life, we must keep the anal area clean to avoid inducing anal diseases that affect the health of the body.

1. Cecum: The cecum is mainly located at the beginning of the patient's large intestine and is also the shortest part inside the large intestine. It can prevent the contents of the large intestine from flowing back, decompose electrolytes, and play a role in excreting feces.

2. Appendix: The appendix is ​​the longest and thinnest blind tube inside the large intestine. It is usually located in the middle of the ileum and cecum, and the distal end is also in a closed state. It can secrete a lot of digestive enzymes to help patients maintain gastrointestinal flora and balance.

3. Colon: The colon is located between the transverse colon and the ascending colon. It can absorb water, sodium, electrolytes and other substances, and can also secrete mucus, which is stored in the descending colon and sigmoid colon and quickly excretes feces.

4. Rectum: The large intestine is an important part of the human digestive system. It can quickly absorb the water in food residues and turn food residues into feces. The rectum can help patients completely remove waste inside the anus, that is, at the end of the intestinal tube.

5. Anal canal: The anal canal is a part of the body's organs. It is located near the anus and is also the end of the digestive tract. It can prevent feces from overflowing. At the same time, when the patient defecates, the anal sphincter relaxes to help the feces be discharged quickly.
