Question

The inner lining of the small intestine has numerous finger like projections that are called:
1. enzymes
2. tissues
3. villi
4. cells

Answer 1

Correct Answer - Option 3 : villi

The correct answer villi.

• Intestinal villi are small, finger-like projections that extend into the lumen of the small intestine.
  • The inner lining of the small intestine has many finger-like projections called villi.
  • The villi increase the surface area for absorption.
  • Each villus is covered by a layer of epithelium and contains blood vessels and lymphatic vessels.
  • Food spreads through the epithelium into the blood vessels.

• Enzymes are proteins that help speed up metabolism, or chemical reactions, in our bodies. They build up some substances and break down others. All living things have enzymes. Our body naturally produces enzymes. But enzymes are also in manufactured products and food.
• Tissue can be defined as a group of cells with similar shapes and functions are termed as tissues.
• Cells are the basic building blocks of all living things. The human body is composed of trillions of cells.
