Question

Explain following words Villi​

Answer 1

Answer:

Intestinal villi (singular: villus) are small, finger-like projections that extend into the lumen of the small intestine. ... In other words, increased surface area (in contact with the fluid in the lumen) decreases the average distance travelled by nutrient molecules, so effectiveness of diffusion increases.

Answer 2

$\large {\underline {\pink {\sf {\purple {Villi :}}}}}$

Intestinal villi are tiny, finger-like projections made up of cells that line the entire length of your small intestine. Your villi (villus is the singular, villi is the plural) absorb nutrients from the food you eat and then shuttle those nutrients into your bloodstream so they can travel where they're needed.
