FAQs on Infographics: Digestive System - Science Class 10

1. What are the main functions of the digestive system?
Ans. The digestive system is responsible for breaking down food into smaller components, allowing nutrients to be absorbed into the bloodstream. Its main functions include the ingestion of food, mechanical and chemical digestion, absorption of nutrients, and elimination of waste.
2. How does the digestive process begin?
Ans. The digestive process begins in the mouth, where food is mechanically broken down by chewing and mixed with saliva, which contains enzymes that start the chemical digestion of carbohydrates. This mixture is then swallowed and moves down the esophagus to the stomach.
3. What role does the stomach play in digestion?
Ans. The stomach plays a critical role in digestion by mixing food with gastric juices, which contain hydrochloric acid and digestive enzymes. This environment helps to further break down food, particularly proteins, into a semi-liquid form called chyme before it moves to the small intestine for further digestion and nutrient absorption.
4. What is the difference between the small intestine and the large intestine?
Ans. The small intestine is primarily involved in the digestion and absorption of nutrients, while the large intestine mainly absorbs water and electrolytes from the remaining indigestible food matter, forming waste that is eventually excreted from the body. The small intestine is longer and has a greater surface area due to villi and microvilli, enhancing nutrient absorption.
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, stay hydrated, engage in regular physical activity, manage stress levels, and avoid excessive consumption of processed foods and sugars. Additionally, regular medical check-ups can help monitor digestive health.
