peräsuolis

Peräsuoli is the Finnish word for rectum. The rectum is the final section of the large intestine, terminating at the anus. It is a muscular tube that stores feces before they are eliminated from the body through defecation. The rectum plays a crucial role in the digestive system by regulating bowel movements.

The inner lining of the rectum contains specialized cells that help in the absorption of water and electrolytes. It also secretes mucus, which lubricates the passage of feces. The rectum's ability to expand allows it to hold significant amounts of waste before signaling the body's need to defecate.

Conditions affecting the peräsuoli can include inflammation, such as proctitis, which can cause pain, bleeding, and a feeling of incomplete bowel emptying. Other issues can involve obstructions, polyps, or cancers. Medical professionals diagnose and treat conditions of the rectum through various methods, including physical examinations, endoscopic procedures like sigmoidoscopy, and imaging tests. Understanding the anatomy and function of the peräsuoli is essential for maintaining gastrointestinal health.
