FAQs on Digestion of Food Video Lecture - Biology for JAMB
| 1. What is the process of digestion? |  |
Ans. Digestion is the process by which our body breaks down food into smaller molecules that can be absorbed and used for energy, growth, and repair. It involves both mechanical and chemical processes, starting from the mouth where food is chewed and mixed with saliva, to the stomach where it is further broken down by stomach acid and enzymes, and finally to the small intestine where nutrients are absorbed into the bloodstream.
| 2. How long does it take for food to be digested? | |
Ans. The time it takes for food to be digested varies depending on the type of food and individual factors. On average, it can take around 24 to 72 hours for food to pass through the entire digestive system. However, certain factors such as the fiber content of the food, the individual's metabolism, and any digestive disorders can influence the digestion time.
| 3. What are the main organs involved in digestion? | |
Ans. The main organs involved in digestion are the mouth, esophagus, stomach, small intestine, large intestine, and pancreas. Each organ plays a specific role in the digestion process. The mouth helps in chewing and mixing food with saliva, the esophagus transports food from the mouth to the stomach, the stomach secretes acid and enzymes to break down food, the small intestine absorbs nutrients, the large intestine absorbs water and forms waste, and the pancreas produces enzymes that aid in digestion.
| 4. What are enzymes and how do they aid in digestion? | |
Ans. Enzymes are proteins that act as biological catalysts in the body. They help speed up chemical reactions without being consumed in the process. In digestion, enzymes play a crucial role in breaking down complex molecules into simpler ones. For example, amylase in saliva breaks down carbohydrates, proteases in the stomach break down proteins, and lipases in the small intestine break down fats. This breakdown allows the nutrients to be more easily absorbed by the body.
| 5. What factors can affect digestion? | |
Ans. Several factors can affect digestion, including diet, hydration, stress, and physical activity. A diet high in fiber can promote regular bowel movements and prevent constipation, while a diet low in fiber can lead to digestive issues. Drinking enough water is important for maintaining proper digestion. Stress and anxiety can disrupt the normal functioning of the digestive system. Physical activity helps stimulate the muscles of the digestive tract, aiding in the movement of food through the system.
