Villi in Intestines (Smooth Surface)
■■■■■
A misconception where people might remember the inner lining of the intestines as relatively smooth, overlooking the vast surface area provided by villi.
●
What People Remember
People sometimes remember the inside of the small intestine as having a relatively smooth lining, rather than being covered in projections.
◉
What's Actually True
The inner surface of the small intestine is covered in millions of tiny, finger-like projections called villi (and microvilli on those cells), which drastically increase the surface area for nutrient absorption, making it far from smooth.
