- MOUTH
- ESOPHAGUS
- STOMACH
- The mouth is where food enters the alimentary canal. It is chewed by teeth which start to break food down. Food is mixed with saliva containing enzymes.
- This is a fibromuscular tube which connects the mouth to the stomach. Food is pushed down using a wave-like muscular motion called peristalsis.
- The stomach is a muscular organ where food is mixed with gastric juices. Gastric juice has a low pH and it is used to help digest food and kill potentially harmful bacteria.
- ANUS
- The Digestive System
- LARGE INTESTINES
- SMALL INTESTINES
- The anus is where feces leaves the alimentary canal.
- The large intestines are made up of two parts: the colon and the rectum. In the colon, water is reabsorbed from the food. Feces is stored in the rectum.
- The small intestines have three parts: the duodenum, the jejunum and the ileum. Here, food is mixed with enzymes and bile. The enzymes speed up the digestion process. Nutrients are then absorbed into the bloodstream.
