FAQs on Learning Poster: Journey of Food in Body
| 1. How does food travel through the digestive system step by step? |  |
Ans. Food travels through the mouth, oesophagus, stomach, small intestine, and large intestine in sequence. In the mouth, teeth break food into smaller pieces while saliva begins digestion. The food then moves down the oesophagus to the stomach, where acids further break it down. The small intestine absorbs nutrients, and the large intestine removes water before waste exits the body.
| 2. What happens to food inside the stomach during digestion? | |
Ans. The stomach churns food into a paste-like mixture called chyme using strong muscular contractions and digestive juices containing acids and enzymes. These gastric juices break down proteins and fats, transforming solid food into a semi-liquid form. The stomach's role is crucial in the digestive process, preparing food for nutrient absorption in the small intestine over several hours.
| 3. Where are nutrients actually absorbed in the digestive tract? | |
Ans. The small intestine is the primary site for nutrient absorption in the digestive system. Its walls contain millions of tiny finger-like projections called villi that increase surface area for absorbing glucose, proteins, and fats into the bloodstream. These absorbed nutrients then travel throughout the body to provide energy and support growth and development in Class 4 students.
| 4. Why does food need to be chewed properly before swallowing? | |
Ans. Chewing breaks food into smaller pieces, increasing surface area for digestive enzymes to work effectively throughout the journey of food in the body. Saliva in the mouth also starts chemical digestion by breaking down carbohydrates. Proper chewing prevents choking and helps the oesophagus move food smoothly to the stomach, making the entire digestive process more efficient and complete.
| 5. What is the role of the large intestine in completing the digestive journey? | |
Ans. The large intestine absorbs remaining water and minerals from undigested food material, forming solid waste called faeces. This final stage of the food journey in the body is essential for maintaining hydration and extracting last nutrients. Beneficial bacteria in the colon also produce certain vitamins. The large intestine then stores waste until it's eliminated through the rectum and anus.
