Q. What is the human digestive system?
Solution:
The digestive system is a group of organs that break down food into smaller parts so the body can use it for energy and growth.
How the digestive system works?
1. Mouth: Digestion starts in the mouth. We chew food into small pieces, and saliva makes it soft.
Example: When you eat bread, saliva helps break it down.
2. Food Pipe (Esophagus): The chewed food goes down a tube called the food pipe to reach the stomach.
3. Stomach: The stomach mixes food with special juices (acids) that break it down further into a thick liquid.
Example: When you eat rice, the stomach juices help dissolve it.
4. Small Intestine: The food moves to the small intestine, where nutrients like vitamins and proteins are taken into the blood.
Example: Fruits give your body energy because of this step.
5. Large Intestine: The leftover food goes to the large intestine, where water is absorbed, and waste is formed.
6. Anus: The waste leaves the body as poop.
