artiteacher The Small Intestine
Lead: No tennis court inside your tummy, / Response: (No way!) / Lead: Just a cozy studio absorbing yummy! / Response: (Oh yeah!)
artiteacher The folds, villi, and microvilli expand the small intestine's surface area to equal a standard tennis court.
artiteacher Millions of tiny, finger-like projections called villi line the small intestine to maximize nutrient absorption.
artiteacher Swipe nutrients into the bloodstream to learn how the intestines absorb energy.
Intestinal surface: Your small intestine's inner surface area is so folded and packed with tiny villi that it could cover an entire tennis court.
Tiny, finger-like projections on the surface of certain membranes, typically serving to increase surface area. They number between 10 and 40 per square millimeter within the human digestive tract.
