The team observed that the intestinal villi reorganize during pregnancy and breastfeeding, and significantly enlarge, doubling their surface area. The studies were carried out in genetically ...

The efficiency of nutrient absorption declines with age due to a reduction in the intestinal surface area. This can result in deficiencies in critical vitamins and minerals, such as vitamin D ...

resulting in a doubling of the intestinal surface area and a striking structural reorganization. The researchers also provide the first genetic and mechanistic evidence of how this intestinal ...

leading to an increase in the intestinal surface area (Fig. 1). This expansion of the villi in pregnancy and lactation was impaired in mice engineered to lack RANK–RANKL signalling in the ...

2011;68(23):2241-2247. Surface area for drug absorption The villi and microvilli responsible for the vast absorptive surface in the small intestine are of highest concentration in the duodenum ...

increasing the surface area. Meanwhile, saliva coats those pieces, delivering enzymes that help break down the food. Finally, once swallowed, the stomach acids turn any remaining food pieces into ...

This pH-dependence of absorption seemed to wield more influence than the increased intestinal surface area available for absorption in the jejunum and ileum. In one such study Murray et al.
