The rectum is approximately 20 cm long. It is continuous with the sigmoid colon and anal canal and functions as a reservoir for feces before excretion. Histologically, the rectum resembles the colon with straight tubular glands that extend through the thickness of the mucosa. The glands are almost entirely lined by mucous-secreting goblet cells but some scarce enterocytes are also seen.

How Does the Digestive System Work for Kids | DK Find Out

The digestive system is essentially a very long tube that stretches from the back of the mouth to the anus. When we eat, food passes down the oesophagus to the stomach, squeezed by regular contractions — this is called peristalsis. When the food reaches the stomach, it is broken down into a mushy liquid called chyme by acids and enzymes. The chyme then passes into the small bowel, which is about 2 metres 7 feet long in newborn babies and grows to about 6 metres 20 feet long by adulthood. It is made up of three parts. The first section is called the duodenum which is connected to the stomach.
