Explanation:
Rectum. The lower end of your large intestine, the rectum, stores stool until it pushes stool out of your anus during a bowel movement.
It connects the sigmoid colon to the anal canal. It starts at the height of S2-S3 and ends at the perineum. It is approximately 12 - 16 cm long and is subdivided into three parts:
The upper of the three parts lies intraperitoneally
The middle of the three parts lies retroperitoneally
The lower of the three parts lies under the pelvic diaphragm and therefore extraperitoneally.
It is vital for the water resorption as well as for the resorption of electrolyte from the stool and plays a key role in the defecation process.
