villi

At this period, the developing circulatory system allows maternal- embryonic nutritive and gaseous changes at the chorionic villi.

They can use a camera capsule to inspect the state of your villi and make a recommendation.

Also, the images depict cells all over the body; not just in the small intestine and certainly not villi.

The only way to test for this if you do not have the antibodies they test for to make a diagnosis is to get a biopsy of your gut villi.

Celiac disease causes the body to destroy villi and they can see that under the microscope.

Harvard iirc showed how the extra fructose in diet corresponded to longer villi in the gut.

The human gut uses the same trick to maximise getting food into you blood via villi.

This is, if the villi go back to having the length they had if they stop feeding the mice fructose.

We don't notice until middle age, when the villi start losing their ability to regenerate.

Enhanced (all-)nutrient absorption through fructose-induced villi surface enlargment (in mice) is a new fact, no?

Crypts are grooves between the villi, which are the small fingerlike projections that line the small intestine and promote nutrient absorption.

This is a shrinking and flattening of the villi due to repeated gluten exposure.

Villi are tiny “fingers” of tissue that line your intestines, increasing it’s surface area and allow absorption of nutrients and water.

This is not really true[0]: > In the villi, these vessels eventually branch to form an extensive arterio-capillary-venous system, bringing the fetal blood extremely close to the maternal blood; but no intermingling of fetal and maternal blood occurs ("placental barrier").

> really bad food allergies like Coeliac Coeliac is just a word that means "relating to the abdomen", Coeliac Disease is a disease of the abdomen characterized by an immune response to gluten that causes the villi in the intestines to consume themselves, among other characteristic symptoms.

"Also, the images depict cells all over the body; not just in the small intestine and certainly not villi." The images are clearly presented in such a way as to suggest that simple osmosis between cells and seawater-containing blood is the operative factor in determining hydration.

Villi expand the surface area of the gut and help the body to absorb nutrients, including dietary fats, from food as it passes through the digestive tract.
