The gall bladder plays an essential role in digestion. Between meals, it concentrates and stores the bile secreted by the liver. During meals, following the arrival of lipids in the duodenum, the gallbladder evacuates the bile it contains through two mechanisms, one reflex nerve and the other hormonal. The role of bile is to cause the emulsion of dietary fats, so that they can be absorbed by the intestinal mucosa and pass into the bloodstream. Do you have digestive problems?
