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

Food is an essential product for the survival of all living beings. The food that living organisms consume is composed of various components, of which the major ones are proteins, fats, and carbohydrates. Additionally, vitamins and minerals are also necessary, but in smaller quantities.

Food is the source of energy and organic materials for living organisms to properly grow and repair body tissues. The water we drink has a significant role in metabolic processes occurring inside the body and prevents the body from getting dehydrated. Biomacromolecules inside the food that living organisms consume are of no use to their body in the matter's original form. Such molecules need to be broken down and changed into simpler substances in the digestive system

This process of conversion or breakdown of complex food materials into small absorbable substances is known as digestion that is performed by the body's digestive system through biochemical and mechanical methods. To learn more about this breakdown of food articles, read the below description.

  • Digestive System in Living Organisms
  • How is food digested?
  • How are digested products absorbed?
  • Drawbacks of the Digestive System

The process of food digestion and absorption, which is a critical function in living entities have been enlightened in this chapter. The chapter has been put under Unit V - 'Human Physiology' of Biology syllabus for class 11. Mainly, the topics discussed under this chapter are the types of bodily functions that occur at the same time when digestion and absorption of food take place, like locomotion, exchange of gases, secretion of juices, etc.

Other topics explained here are different types of enzymes released during the process, the role of different organs and microorganisms in the process, and the use of various microprocessors. The concluding part of this chapter talks about the importance of each food material that is included in our diet.
