21. Villi died after a long illness in Rapallo, where she lived for about thirty years.22. Several days later, chorionic villi in the forming placenta anchor the implantation site to the uterus. 23. The villi are connected to the blood vessels so the circulating blood then carries these nutrients away. 24. Villus capillaries collect amino acids and simple sugars taken up by the villi into the blood stream. 25. This also contains villi and vitamin B12; bile acids and any residue nutrients are absorbed here. 26. These structures, called the chorionic villi , carry the fetal blood supply often sampled in prenatal tests. 27. Gluten flattens the villi , the tiny fronds inside the walls of the small intestine that absorb nutrients. 28. When looking for microscopic villi , trophoblast, fetal parts, and background gestational changes in the endometrium. 29. Villi increase the internal surface area of the intestinal walls making available a greater surface area for absorption.30. After circulating through the capillaries of the villi , blood returns to the embryo through the umbilical vein.
