Why are there so many villi found in the small intestine?
Tough one. I love science but math is my arch enemy so I'll list
the facts in case I forgot to carry a 1. 20-40 villi per square
millimeter / 600 square feet in an adult's small intestine / 304.8
millimeter per square foot / 600 X 304.8 = 182,880 square
millimeters in small intestine / 182,880 X 20 = 3,657,600 villi /
182,880 X 40 = 7,315,200 villi. THERE ARE ANYWHERE FROM 3,657,600 -
7,315,200 VILLI IN THE AVERAGE ADULT'S SMALL INTESTINE.
