FAQs on Digestive System - Class 7

1. What is the main function of the digestive system?
Ans. The main function of the digestive system is to break down food into smaller molecules that can be absorbed by the body and provide nutrients for energy.
2. How does the digestive system work?
Ans. The digestive system starts with the mouth where food is chewed and mixed with saliva. It then travels through the esophagus to the stomach, where it is further broken down by stomach acids. From there, it enters the small intestine where nutrients are absorbed into the bloodstream. The remaining waste then moves to the large intestine where water is absorbed, and finally, it is eliminated as feces.
3. What are the main organs of the digestive system?
Ans. The main organs of the digestive system include the mouth, esophagus, stomach, small intestine, large intestine, liver, gallbladder, and pancreas. Each organ plays a specific role in the digestion and absorption of food.
4. How does the liver contribute to the digestive system?
Ans. The liver produces bile, which is stored in the gallbladder and released into the small intestine to help break down fats. It also detoxifies harmful substances, stores vitamins and minerals, and produces proteins necessary for blood clotting.
5. What are some common digestive system disorders?
Ans. Some common digestive system disorders include acid reflux, gastritis, ulcers, irritable bowel syndrome (IBS), and constipation. These disorders can cause symptoms such as heartburn, stomach pain, bloating, diarrhea, or constipation. Treatment for these disorders may vary depending on the specific condition and severity.
