The template talks about the rectum which is a component of the lower gastrointestinal tract. The rectum is a continuation of the colon, and connects to the anus.
The rectum acts as a temporary storage site for feces. As the rectal walls expand due to the materials filling it from within, stretch receptors from the nervous system located in the rectal walls stimulate the desire to defecate. If the urge is not acted upon, the material in the rectum is often returned to the colon where more water is absorbed from the feces. When the rectum becomes full, the increase in rectal pressure forces the walls of the anal canal apart, allowing the fecal matter to enter the canal. The rectum shortens as material is forced into the anal canal and waves propel the feces out of the rectum. The free Digestive System PowerPoint template is set against a black background and has the figure of a human body in a bent position and the main organs of the digestive system in red. The template can be used by doctors to talk about rectum and the functions. It can be used by students in projects. It can also be used by teachers for teaching the different organs in the digestive system.
