FAQs on Infographics: The Digestive System - Science for Class 4

1. What are the main organs involved in the digestive system?
Ans.The main organs involved in the digestive system include the mouth, esophagus, stomach, small intestine, large intestine, rectum, and anus. Each organ plays a specific role in breaking down food, absorbing nutrients, and eliminating waste.
2. How does the digestive process work?
Ans.The digestive process begins in the mouth, where food is mechanically broken down by chewing and mixed with saliva. It then travels down the esophagus to the stomach, where it is mixed with gastric juices. From the stomach, the partially digested food moves into the small intestine, where most nutrient absorption occurs, and finally into the large intestine for water absorption and waste elimination.
3. What role do enzymes play in digestion?
Ans.Enzymes are crucial for digestion as they speed up the chemical reactions that break down food into smaller molecules. Different enzymes target specific nutrients: amylase breaks down carbohydrates, proteases digest proteins, and lipases break down fats, facilitating nutrient absorption in the intestines.
4. What is the significance of gut bacteria in the digestive system?
Ans.Gut bacteria, also known as gut microbiota, play a significant role in digestion by helping break down complex carbohydrates that the human body cannot digest on its own. They also produce essential vitamins, aid in immune function, and help maintain overall gut health.
5. What are common digestive disorders, and what are their symptoms?
Ans.Common digestive disorders include gastroesophageal reflux disease (GERD), irritable bowel syndrome (IBS), and celiac disease. Symptoms may vary but often include stomach pain, bloating, gas, diarrhea, constipation, and heartburn. It's essential to consult a healthcare professional for diagnosis and treatment.
