DIGESTIN’ IN THE SMALL INTESTINE

HEALTH PEARL #809

The next part of our digestion involves the SMALL INTESTINE.

After proteins, fats, and carbohydrates have been liquified by the acids in the stomach, and further broken down in the duodenum with the help of pancreatic enzymes and bile, GRAVITY will now lead these micronutrients into our small intestine.

In the small intestine section called JEJUNUM, Bacteria and Yeast are the primary workers. 

Of course some acids and bile are coming in with the nutrients, and some additional breakdown is taking place. However, here is where a lot of digestion happens, primarily involving simple sugars, amino acids, and fats. 

The JEJUNUM’s inside wall contains villi, which look like fingers or hair. THESE villi, along with intestinal muscle contractions (called PERISTALSIS) move the nutrients forward down the pipe, while bacteria grab what they can and move it between the villi, through microscopic holes in the intestinal wall, and then into the blood stream.
