Solution
Digestive system
The major constituent organs of the human digestive system are the buccal cavity, oesophagus, stomach, small intestine, large intestine, rectum, and anus.
- Buccal cavity: It includes the teeth, saliva and tongue. The teeth break down the food. Digestion of food begins in the mouth. The tongue helps in the chewing and swallowing of food.
- Oesophagus: The food passes from the mouth, down the oesophagus, into the stomach as a result of the movement of the walls of the oesophagus.
- Stomach: It mixes the food received from the oesophagus with digestive juices.
- Small intestine: The food from the stomach moves into the small intestine, which receives intestinal juices from two.
- Gallbladder: Stores bile and releases it into the small intestine when needed.
- Pancreas: Produces enzymes that help digest proteins, fats, and carbs.
- Glands: the liver and pancreas. These juices help in the further digestion of food.
- Large intestine: Water is absorbed in the large intestine.
- Rectum and anus: Undigested food particles are thrown out with the help of the rectum and anus.
