Explain the location and function of villi from Chapter 2 of NCERT Solutions for Class 7 Science.
The finger-like projections or outgrowth present in the small intestine of our digestive system are called villi. The surface area for food absorption and digestive secretion is increased with the help of villi. To help students understand this concept clearly, diagrams are included in the solutions to enable visual learning. Students who are not able to answer the questions from the NCERT textbook can access the solutions from BYJU’S to get a clear idea of the concepts. The solutions help students to analyse the areas in which they are lagging behind and work on them for a better score.
