Question

the function of a jejunum

Answer 1

The Function of the Jejunum

The jejunum, along with the other areas of the small intestine, is responsible for absorbing nutrients from digested food into the bloodstream.

The jejunum is able to absorb these nutrients because it is lined with finger-like projections that are called villi.  The villi  absorb nutrients in the form of minerals, electrolytes, and carbohydrates, proteins, and fats that were consumed in the form of food. The nutrients are absorbed into the bloodstream where they can be utilized for energy by the entire body.

The jejunum, as well as the rest of the small intestine, make it possible to change food into energy, powering the body for daily activities. Without the small intestine, food would pass through the body but we would gain no nutrients, and would quickly starve.  

Answer 2

Answer:

Explanation:

The jejunum is the middle segment of the small intestine found between the duodenum and the ileum. Most of the nutrients present in food are absorbed by the jejunum before being passed on to the ileum for further absorption.

NOTE: no chemical reactions or actions through enzymes and etc.... do not take place in the jejunum.
