NCERT Question 5 - Chapter 2 Class 7 - Nutrition in Animals

What are villi? What is their location and function?

Answer:

• After the pancreatic juice acts on carbohydrates, fat and proteins, the digested food passes into the blood vessels in the wall of the intestine.
• This process is called Absorption .
• The inner wall of the small intestine has many finger-like outgrowths called villi .
• These increase the surface area of the small intestine, hence increasing absorption .
