Question

explain how digested food gets absorbed into the blood.​

Answer 1

hi mate,

==> we know that the small intestine has millions of tiny finger-like projections called villi.

==>These villi increase the surface area for more efficient food absorption. that's why

small intestine is designed to have maximum absorption of food.

==>Within these villi, many blood vessels are present that absorb the digested food and carry it to the blood stream.

==> we know that the Columnar epithelium is located in the digestive tract such as the stomach, large intestine, small intestine and functions as a barrier to bacteria and other microbes but permits the absorption of digested food.

i hope it helps you.
