The inner lining of the intestine has folds in it so as to increase the surface are. This greater aids in the absorption of nutrients from the gut. The larger the surface area, the greater the rate of absorption.
the lining of the small intestine has folds, and are covered with finger-like projections called villi, which are covered with thousands of micro-villi
rugae It's not rugae - for stomach. Small intestine wall is plicae circulares.
The villi are the tiny finger-like projections that cover the folds of the small intestine. The singular of villi is villus.
folds and villi
Folds increase surface area and therefore a greater surface area for gas exchange
The Greater Omentum
It increases the surface area available for absorption of digestion nutrients.
The surface is made up of many small wrinkled folds which increases the surface area.
Villi (might be mispelled). They're kind of like microscopic hairs that help absorb nutrients in the small intestine leading to a greater surface area.
Folds increase the surface area to volume ratio.Imagine a circle with folds all around the edge and another circle the same size with a flat edge. Both circles have the same volume, but the one with the folds has a much larger surface area.
Many folds and tiny microvilli line the small intestine. The microvilli are like tiny fingers and these help increase the surface area.
