Bile is a yellow-brown or dark green fluid that helps with the digestion of lipids and the excretion of some waste products. The liver continuously produces bile, which the body stores in the gallbladder. After digestion, the bile enters the duodenum of the small intestine. During each of these stages, the levels of water, bile salts, waste products, fats, and inorganic salts in the bile fluctuates. Health professionals refer to bile with different names depending on its location and composition.


1. Production

The liver is one of the largest and most important organs. It is responsible for many of the metabolic functions that keep the body operational, including breaking down and converting substances, extracting energy, and removing toxins. Hepatocytes, special liver cells that filter blood and direct many of these metabolic functions, are also in charge of the production and secretion of bile. An average adult liver creates between 400 and 800 milliliters of bile each day.
