What is the Digestive System?
The different organs and body parts of the human body that are involved in the process of digestion constitute the digestive system.
The human digestive system includes the gastrointestinal tract and the other accessory organs of digestion.
Digestive System Organs:
There are five types of glands present in the digestive system—
- Salivary glands, liver, gall bladder, pancreas and gastric glands of the stomach.
- They secrete juices that facilitate the process of digestion.
Glands : These are tissues or organs that produce substances required by other tissues or organs to work properly. Glands can be of two types—exocrine and endocrine.
Bile : A fluid made and secreted by the liver and stored in the gall bladder. Bile aids in digestion and helps in the breakdown of food.

- When a baby grows inside the womb, her liver produces blood that carries oxygen to all parts of the body.
- The small intestine, as the name suggests, isn’t small at all. If the coiled structure is stretched out, it will cover space of the size of an entire tennis court.
- You must have heard your stomach make sounds. But do you know why it does so? It sounds the loudest when your stomach is empty. It happens due to the movement of fluids and gases in your stomach. The sound is described as ‘borborygmi’.
