intestinal villi multitudinous threadlike projections covering the surface of the mucous membrane lining the small intestine, serving as the sites of absorption of fluids and nutrients.
synovial villi slender projections from the surface of the synovial membrane into the cavity of a joint; called also haversian glands.

in·tes·ti·nal vil·li

[TA]
projections (0.5-1.5 mm long) of the mucous membrane of the small intestine; they are leaf-shaped in the duodenum and become shorter, more finger-shaped, and sparser in the ileum.

Apoptotic cells were mainly distributed in the lamina propria of the intestinal villus in control, 40, 80 and 160 mg/L groups and their number significantly (p <0.01) decreased in 80 mg/L group compared with control group.
Compared with the LPS group, the villus height and width were also markedly decreased in the visfatin+LPS co-stimulated group (p<0.01), suggesting that the damage to the intestinal villus was perhaps caused by the synergy between visfatin and LPS, or visfatin could regulate the changes induced by LPS.
