FAQs on Human Digestive System Video Lecture - Class 10

1. What is the function of the human digestive system?
Ans. The human digestive system is responsible for breaking down food into smaller molecules that can be absorbed by the body. It also helps in the absorption of nutrients, elimination of waste, and maintaining the body's overall balance.
2. What are the main organs of the human digestive system?
Ans. The main organs of the human digestive system include the mouth, esophagus, stomach, small intestine, large intestine, liver, gallbladder, and pancreas. Each organ has a specific role in the process of digestion.
3. How does digestion occur in the human digestive system?
Ans. Digestion in the human digestive system begins in the mouth, where food is chewed and mixed with saliva. It then travels down the esophagus and into the stomach, where it is further broken down by stomach acids. The partially digested food then enters the small intestine, where enzymes from the pancreas and bile from the liver help in the breakdown of nutrients. The nutrients are absorbed by the small intestine and transferred to the bloodstream. The remaining waste then moves into the large intestine, where water is absorbed, and the waste is formed into feces for elimination.
4. What is the role of the liver in the human digestive system?
Ans. The liver plays a vital role in the human digestive system. It produces bile, which helps in the breakdown of fats. The bile is stored in the gallbladder and released into the small intestine when needed. The liver also detoxifies harmful substances, metabolizes nutrients, and stores vitamins and minerals.
5. What are some common digestive system disorders?
Ans. Some common digestive system disorders include acid reflux, gastritis, ulcers, irritable bowel syndrome (IBS), constipation, diarrhea, and gallstones. These disorders can cause various symptoms such as abdominal pain, bloating, indigestion, and changes in bowel movements. It is important to maintain a healthy lifestyle and seek medical advice if experiencing persistent digestive problems.
