FAQs on Digestive System - Biology, General Science Video Lecture - IBPS PO Prelims & Mains Preparation - Bank Exams

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 components, such as nutrients, that can be absorbed by the body. This process involves the mechanical and chemical digestion of food, as well as the absorption and elimination of waste.
2. How does the digestive system work?
Ans. The digestive system begins with the ingestion of food through the mouth, where it is mechanically broken down by chewing and mixed with saliva. The food then travels down the esophagus and into the stomach, where it is further broken down by stomach acid and enzymes. From the stomach, the partially digested food enters the small intestine, where it is broken down into even smaller molecules and absorbed into the bloodstream. The remaining waste passes into the large intestine, where water is absorbed and the solid waste is formed. Finally, the waste is eliminated through the rectum and anus.
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 nutrients. For example, the liver produces bile, which helps break down fats, while the pancreas produces enzymes that aid in the digestion of proteins, carbohydrates, and fats.
4. What are some common digestive system disorders?
Ans. Some common digestive system disorders include gastroesophageal reflux disease (GERD), irritable bowel syndrome (IBS), Crohn's disease, ulcerative colitis, and gallstones. These disorders can cause symptoms such as heartburn, abdominal pain, diarrhea, constipation, and nausea. Treatment options for these disorders vary depending on the specific condition and may include medication, lifestyle changes, and surgery.
5. How can I maintain a healthy digestive system?
Ans. To maintain a healthy digestive system, it is important to eat a balanced diet rich in fiber, fruits, vegetables, and whole grains. Staying hydrated, exercising regularly, and managing stress can also contribute to a healthy digestive system. Additionally, avoiding smoking and excessive alcohol consumption, as well as practicing good hygiene and food safety, can help prevent digestive system disorders.
