The term "rektum" refers to the final section of the large intestine in the human body. It serves as a storage area for feces before they are expelled from the body through the anus. The rectum is typically about 12 centimeters long and plays a crucial role in the digestive system. In addition to its primary function in waste elimination, the rectum contains nerve endings that help signal when it is time to defecate. This process is essential for maintaining digestive health and overall bodily function. Proper care and awareness of rectal health can prevent various medical issues.
