It causes premature ageing of the skin by a process called glycation. This is where excess sugar in the blood attaches itself to lipids, nucleic acids and proteins (especially your collagen) to form âadvanced glycation end Â­productsâ or AGEs, which accelerate the ageing process and so cause wrinkly skin.
What is the role of villi in digestive system? the role of the villi is that it increases the surface area so that when food passes through the small intestine the food will get caught on the villi and the nutrients are ab â¦ sorbed into the blood.
The villus is the main structure of the small intestine, villi the the plural. The inner wall of the small intestine has many ridges each containing many villi, each villus has a network of blood & lymohatic vessels. After digestion, nutrients goes to the small intestine, then get absorbed into the blood, the villi does the absorption and transport the nutrient into the blood & the lymph.
