What is liver physiology?

liver is essential for body metabolism. The physiology of the liver is focused on cells called hepatocytes, which contain thousands of enzymes that control the metabolic processes of the human body. The processes in the liver decompose compounds, store nutrients and send compounds to be secreted by bile or urine. The liver also filters out damaged blood cells and synthesizes plasma proteins such as collision factors and a growth factor similar to insulin. It is structured into multiple segments and lobles organized around a complex blood supply. Segments consist of structures called lobules. These include hexagon areas of liver cells that are arranged around a vein that passes between cells in sinusoids. Blood passes through veins in these spaces into the central vein of the liver, allowing 1.5 liters (about 0.4 gallons) blood to flow every minute.

Red blood cells (RBC) are cleaned if they are damaged or at the end of a 12 -day life cycle through a process known as phagocytosis.Hundreds of RBCs with a minute are removed along with bacteria Kupffer cells in sinusoids. Enzymes that are part of the liver physiology are also able to decompose and remove toxins from the blood supply. The amino acids released by the digestive system pass through the liver and into the blood to build the proteins needed for the energy.

The protein metabolism is driven by the liver. Part of the liver physiology is also the ability of the organ to store different compounds. Excess glucose is removed from the blood and the liver can store glycogen in the amount of up to 8% of its weight. It also stores a 10 -month supply of vitamin A, the annual offer of B _{12 and three to four months of vitamin D. Most of the vitamin A stored in the body is contained in the fat droplets in the liver.}

liver physiology also includes regulation of blood coagulation. Vitamin K shops allow coagulation factors to synthesize. D digestion of fats and absorption are allowed by other liver functions.Bile salts can break fat clusters and fat -soluble fatty acids are metabolized and stored as body fat. If not for liver physiology, urea and other by -products do not enter the blood to be filtered, plasma is not filtered, causing jaundice and sugars do not transfer to the blood, resulting in death.
