FAQs on Digestive System - Nutrition in Animals Video Lecture - Class 7
1. What is the role of nutrition in the digestive system of animals? |
 |
Ans. Nutrition plays a crucial role in the digestive system of animals as it provides the necessary nutrients for their growth, development, and overall functioning. The digestive system helps break down food into smaller molecules that can be easily absorbed by the body. These nutrients are then used for energy production, building and repairing tissues, and maintaining various physiological processes. Without proper nutrition, animals may suffer from malnutrition, weakened immune system, and other health issues.
2. What are the main components of the digestive system in animals? |
 |
Ans. The main components of the digestive system in animals include the mouth, esophagus, stomach, small intestine, large intestine, and rectum. The mouth is responsible for chewing and breaking down food, while the esophagus transports the food from the mouth to the stomach. The stomach further breaks down the food through the action of digestive enzymes and acids. The small intestine is where most of the nutrients are absorbed, while the large intestine helps in the absorption of water and electrolytes. Finally, the rectum stores and eliminates waste materials from the body.
3. How does the digestive system of animals process and absorb nutrients? |
 |
Ans. The digestive system of animals processes and absorbs nutrients through a series of steps. Firstly, food is ingested through the mouth and broken down into smaller pieces through chewing and mixing with saliva. It then travels down the esophagus and enters the stomach, where it is further broken down by stomach acids and digestive enzymes. The partially digested food then moves into the small intestine, where nutrients are absorbed through the lining of the intestine into the bloodstream. From there, the nutrients are transported to various cells and tissues of the body to be utilized for energy and other functions.
4. What are some common digestive disorders in animals? |
 |
Ans. Some common digestive disorders in animals include diarrhea, constipation, gastritis, and gastroenteritis. Diarrhea is characterized by loose and watery stools, often caused by viral or bacterial infections, dietary changes, or stress. Constipation, on the other hand, is the difficulty in passing stools and can be caused by inadequate fiber intake or dehydration. Gastritis refers to inflammation of the stomach lining, which can be caused by infections, medications, or certain diseases. Gastroenteritis is the inflammation of the stomach and intestines and can lead to symptoms like vomiting, diarrhea, and abdominal pain.
5. How can animals maintain a healthy digestive system? |
 |
Ans. Animals can maintain a healthy digestive system by following a balanced and nutritious diet, consuming adequate amounts of water, and avoiding harmful substances. A diet rich in fiber, vitamins, and minerals helps promote proper digestion and prevents digestive disorders. Regular exercise is also important as it helps stimulate bowel movements and improves overall gut health. Additionally, animals should be protected from exposure to toxins, parasites, and infectious agents that can disrupt the digestive system. Regular veterinary check-ups and vaccinations are also crucial in maintaining a healthy digestive system in animals.
