Vedclass · Answer

(B) $1$. The inner lining of the small intestine has numerous finger-like projections called $villi$.$2$. These $villi$ significantly increase the surface area for the absorption of digested food.$3$. Furthermore, the cells covering these $villi$ have even smaller, hair-like projections called $microvilli$.$4$. Together, $villi$ and $microvilli$ increase the intestinal absorptive surface area by approximately $30$-fold and $600$-fold, respectively, allowing for highly efficient nutrient absorption.
