How does the liver regulate blood nutrients?

The liver is the largest accessory organ of the digestive tract; it is also one of the most important organs in the body, performing over 500 discrete functions. One function of the liver is to receive the products of digestion, and then release into the bloodstream those nutrients needed throughout the body. The liver also processes and stores monosaccharides, triglycerides, and amino acids, and plays a major role in regulating these energy nutrients. For instance, after we eat a meal, the liver picks up excess glucose from the blood and stores it as glycogen, releasing it into the bloodstream when we need energy later in the day. It also stores certain vitamins and manufactures blood proteins. The liver can even make glucose from various food nutrients when necessary to make sure that our blood glucose levels stay constant. The liver also synthesizes bile, which, is then concentrated and stored in the gallbladder until needed.
