An expert breaks down the entire digestion process.

Theoretically, for drugs that easily penetrate the intestinal mucosa, reduced villus blood flow could delay diffusion and, therefore, the rate of absorption. For example, the absorption rate for ...

By bypassing major portions of the small intestine, Roux-en-Y bypass procedures drastically reduce the surface area for absorption. Villi and microvilli give the small intestine a much greater ...

These villi and microvilli increase the surface area available for the absorption of nutrients. In the small intestine food that has already been broken down by chewing and stomach enzymes is ...

Villi facilitate the absorption of nutrients from food. Erosion of villi makes them flattened, causing trouble absorbing nutrients. Though genetic, celiac disease may develop anytime in a person ...

When a person with celiac eats food containing gluten, their immune system responds by damaging the villi in the small intestine. This makes absorption of nutrients nearly impossible. Only one ...

Additionally, the increase in villus length was associated with increased nutrient absorption, weight gain and fat accumulation in the animals. "Fructose is structurally different from other ...

Explore how particle drift influences oral drug absorption and why flux tools are essential for accurate assessment.

It is this loss of villi called villous atrophy that leads to the impairment of nutrient absorption from the small intestine. The symptoms of the disease should improve once the patient has been ...
