Villus has some adaptive features that enables the Absorption of food. Lets discover them together.👍❣️
Adaptation Of The Villus
1. As from the above picture, we can see that villus has finger- like shape this actually increases the surface area for absorption.👍
2. The surface area is further increases by the microvilli which are folded cell membrane of the epithelial cell of the villus.🤟
3.It has very thin epithelium which is one-cell thick. It shortens the distance for rapid diffusion of food into the blood vessels.🤓
4. The epithelial cells of the villus contain a large number of Mitochondria which supply large amount of energy for the active transport of digested products.😃
5. Villus also contains a network of capillaries that encloses a Lacteal at center as seen from the above picture. It helps to maintain a steep concentration gradient of food molecules and results in rapid transportation.😁
