Question

4. Villi contain
that absorb nutrients, which are then transported through the body.

Answer 1

Villi contain **microvilli** on their surface, which are tiny hair-like projections that increase the surface area for absorption. These structures are lined with epithelial cells that absorb nutrients from the digested food in the small intestine. Once the nutrients are absorbed, they enter the bloodstream through capillaries in the villi, which then transport them throughout the body.
