What does the anus look like from the inside from the view from an endoscope colonscope or pill cam?

From the inside, the anus appears as a circular opening leading to the rectum, with a pinkish hue due to its mucosal lining. The tissue is typically smooth and may show folds known as anal columns. The endoscopic view allows for the observation of any abnormalities, such as inflammation or lesions, along the rectal wall. The internal structure can vary slightly among individuals, but overall, it is designed to facilitate the passage of stool.
