The Liver Has 6 Main Functions:
1 Digest food: extract essential nutrients for the body such as carbohydrates, lipids and proteins. And it secretes bile that helps the body absorb fats.
2 Regulate blood glucose and store energy in the form of glycogen (reserve sugar).
3 Eliminate toxic substances: filters and eliminates toxins from what we consume, for example, alcohol and medications.
4 Stores vitamins, fats and minerals.
5 Controls the production and elimination of cholesterol.
6 Produces proteins and clotting factors that the body needs
The liver receives blood rich in nutrients and toxins from the intestine.
As it passes through the liver, the blood is filtered. During this process, toxins are transformed into harmless substances to be later eliminated and protect the body from their harmful effects. Medications, for example, are metabolized through the liver so that our body is able to use them and then eliminate them.
On the other hand, the liver intervenes in the metabolism (synthesis) and regulation of the levels of normal substances in the blood such as carbohydrates (glucose or sugar), lipids (cholesterol and triglycerides) and proteins. It can store or release them into the blood as needed and is a reservoir of vitamins, minerals and clotting substances.
In turn, the liver secretes bile, an essential substance for proper digestion. Bile is made up of bile acids and other substances that help especially to absorb fatty substances (cholesterol, some vitamins, etc.) during digestion. Bile is stored in the gallbladder. When a food rich in fat reaches the stomach, it activates the contraction and emptying of the gallbladder, delivering bile to the intestine. If the amount of bile is insufficient, the sensation of “poor digestion or heaviness” is generated.
Once it has gone through this process, the blood is returned to the general circulation to carry nutrients throughout the body.
