The internal layer of the small intestine is thin and allows nutrients to pass through it easily. The villi in the intestine gives it a larger surface area, allowing even more nutrients to be passed into the bloodstream.
If i understand your question correctly, the small intestine is composed of folds which contain villi which are folds within the folds of the lining of the tract. Also, villi are composed of even more infoldings called microvilli which are even smaller folds. All of these together drastically increase the surface area of the intestine which allows for high levels of nutrients to be absorbed by the colon across its lining.
The small intestine is lined with bumpy cells called villi and micro villi. They increase surface area hugely and have mitochondria in them to release energy. They have a great blood supply to increase diffusion and osmosis. People with coeliac disease have flattenedvilli when they eat certain foods. This tends to make people underweight.
The topography of the small intestines includes villi and microvilli. These structures vastly increase the area of absorption for maximum benefit to the organism.
the inside is covered with a bunch of little hair-like things called vili that absorb the nutrients and send them into the bloodstream
villi and micro villi
The villi
small intestine helps absorb nutrients
To absorb the nutrients from the food and send it to the large intestine
it is adapted to absorbing nutrients due to the villi present in the small intestine.
The role of the villi in the small intestine is to absorb nutrients.
The nutrients absorb
The part of the digestive system that absorbs nutrients is the small intestines. They absorb essential nutrients from food into the blood stream.
