__________ increases the surface area for absorption in intestines:
__________ increases the surface area for absorption in intestines:
The correct option is: C
Explanation of the correct option:
Villi are fingerlike projections on the inner walls of the small intestine which increase the surface area to help in more absorption of digested food. The absorbed food is taken by blood and supplied to all cells of the body which in turn produce energy.
Explanation of the incorrect option:
Option A: Cilia are microtubule-based hair-like organelles that extend from the surface of almost all cell types of the human body.
Option B: The cell membrane is found in all cells and separates the interior of the cell from the outside environment. The cell membrane consists of a lipid bilayer that is semi-permeable that regulates the transport of materials entering and exiting the cell.
Option D: The mass of long thin strands that grow on the head and bodies of people and animals is called hairs
Final answer: Villi increases the surface area for absorption in intestines.
