Peräsuoli

Peräsuoli is the Finnish word for rectum. The rectum is the final section of the large intestine, terminating at the anus. It is a temporary storage site for feces before they are eliminated from the body through defecation. The rectum is approximately 15 centimeters (6 inches) long and is located in the pelvis.

The inner lining of the rectum is a mucous membrane, which lubricates the passage of stool. Muscular layers in the rectal wall help to propel the feces towards the anus. The rectum plays a crucial role in the digestive system by controlling the urge to defecate and regulating bowel movements.

Conditions affecting the peräsuoli can include inflammation, such as proctitis, and structural issues like rectal prolapse. The peräsuoli is also a site for certain types of cancer. Medical examinations of the peräsuoli can involve procedures like a digital rectal exam or a sigmoidoscopy.
