Liver Metabolism and Storage

Flashcards about the liver's storage and metabolic roles.

Glycogen Storage

The liver and muscles store glucose as glycogen.

Insulin's Role in Glucose Metabolism

Insulin, primarily in the liver, lowers or balances blood glucose levels by converting glucose into glycogen.

Glucagon's Role in Glucose Metabolism

Glucagon, in muscle and liver, increases blood sugar when it decreases by breaking down glycogen into glucose.

Liver's Role in Protein Metabolism

The liver plays a crucial role in protein metabolism, including deamination of excess amino acids to produce urea.

Bile Production

The liver produces bile, which is stored in the gall bladder and released into the bile duct for emulsification of lipid products.

Deamination

The process in the liver where excess amino acids are broken down, resulting in the production of urea.

Urea

A waste product formed in the liver from the deamination of amino acids, and it's excreted by the kidneys into urine.

Hepatic portal vein

Carries absorbed digested food (glucose, amino acids, fatty acids, glycerol, vitamins, and mineral salts) from the alimentary duct to the liver.

Hepatic vein

Transports nutrients, vitamin, mineral salt, fibrinogen to major circulatory system.

Liver's Storage Function

The liver stores vitamin and mineral salts.

Bile Emulsification

Bile from the liver emulsifies lipid products.
