NCERT Solutions for Class 11 Biology Chapter 16 - Digestion and Absorption

 

NCERT Solutions for Class 11 Biology Chapter 16 - Digestion and Absorption: Food is one of the basic requirements of all living organisms. The major components of our food are carbohydrates, proteins, and fats. Vitamins and minerals are also required in small quantities. Food provides energy and organic materials for growth and repair of tissues. The water we take in plays an important role in metabolic processes and also prevents dehydration of the body. Biomacromolecules in food cannot be utilized
by our body in their original form. They have to be broken down and converted into simple substances in the digestive system. This process of conversion of complex food substances to simple absorbable forms is called digestion and is carried out by our digestive system by mechanical and biochemical methods.

Here are the important topics of NCERT Class 11 Biology Chapter 16 - Digestion and Absorption mentioned below:

16.1 Digestive System

    16.1.1 Alimentary Canal

    16.1.2 Digestive Glands

16.2 Digestion of Food

16.3 Absorption of Digested Products

16.4 Disorders of Digestive System

Chapter 16 - Digestion and Absorption of Human Physiology will also tell you about the absorptions of digested food. The digested end products are absorbed into the body through the epithelial lining of the intestinal villi. The undigested food (feces) enters into the caecum of the large intestine through the ileocecal valve, which prevents the backflow of the fecal matter. Most of the water is absorbed in the large intestine. The undigested food becomes semi-solid in nature and then enters into the rectum, anal canal and is finally egested out through the anus.

After going through NCERT Class 11 Biology Chapter 16 - Digestion and Absorption of Human Physiology, you must be able to answer the following questions:

  • Q. Describe the digestive role of chymotrypsin. Which two other digestive enzymes of the same category are secreted by its source gland?
  • Q. How are polysaccharides and disaccharides digested?
  • Q. What would happen if HCl were not secreted in the stomach?
  • Q. How does butter in your food get digested and absorbed in the body?

If you have any doubt in answering these questions then, don't worry NCERT Solutions for Class 11 Biology Chapter 16 - Digestion and Absorption will help you to answer them by understanding the concept behind the questions.

Try to answer all the questions which are mentioned in the NCERT Chapter 16 - Digestion and Absorption of Biology by yourself, if not then Solutions for NCERT Class 11 Biology Chapter 16 - Digestion and Absorption is there for you. it will also help you in the preparation of other competitive exams like NEET.
