Intestinal juice secreted by the walls of the small intestine contains enzymes which complete the process of digestion.
The Human Digestive System
- The digestive system is made up of the gastrointestinal tract, along with accessory organs such as the liver, pancreas and gallbladder.
- The hollow organs that make up the gastrointestinal tract (GI tract) include the mouth, stomach, oesophagus, small intestine and large intestine that contains the rectum and anus.
- The digestion process involves the alimentary canal along with various accessory organs and organ systems.
- In humans, the process is quite simple due to our monogastric nature. This implies that we have a one-chambered stomach, unlike other animals such as cows, which have four chambers.
- Some parts of nervous and circulatory systems also play a significant role in the digestion process.
- A combination of nerves, bacteria, hormones, blood and other organs of the digestive system completes the task of digestion.
