Anatomy of the liver education

1. Anatomy of the liver
The liver is situated above the stomach, right kidney, and intestines in the upper right quadrant
of the abdominal cavity, beneath the diaphragm.
The liver is a dark reddish-brown, cone-shaped organ that weighs roughly 3 pounds.
The liver receives blood from 2 different sources, including the following:
● The hepatic artery supplies the organ with oxygenated blood.
● Blood that is rich in nutrients enters from the hepatic portal vein.
Approximately one pint (13%) of the body's blood is always stored in the liver. There are two
primary lobes in the liver. Each is composed of 8 segments, each of which has 1,000 lobules
(little lobes). The common hepatic duct is formed by the union of smaller ducts (tubes) that are
attached to these lobules. The bile produced by the liver cells is transported through the
common hepatic duct to the gallbladder and duodenum, which is the first section of the small
intestine.
Functions of the liver
The liver excretes a substance known as bile and controls the majority of blood chemical levels.
This aids in removing waste from the liver. The liver receives all the blood that exits the
intestines and stomach. This blood is processed by the liver, which also breaks down, balances,
and produces nutrients. It also metabolizes medications to make them more easily absorbed by
the body or nontoxic. The liver is known to have more than 500 essential activities. The
following are some of the more well-known functions:
● production of bile, a digestive fluid that aids in the removal of waste and the breakdown
of lipids in the small intestine.
● manufacturing specific proteins for blood plasma
● production of specific proteins and cholesterol to assist the body in transporting fat
● conversion of extra glucose to glycogen for storage (glycogen can then be converted
back to glucose for energy), as well as to maintain balance and produce glucose as
needed

2. ● control of blood amino acid levels, which serve as the building blocks for proteins
● iron stored in the liver is used by processing hemoglobin for usage.
● Ammonia, a dangerous gas, is converted to urea, a byproduct of protein synthesis that is
expelled in urine.
● removing drugs and other poisons from the blood
● Regulating blood clotting
● creating immunological factors to fight infections and eliminating microorganisms from
the blood
● removal of bilirubin from red blood cells as well. The skin and eyes become yellow when
bilirubin levels rise.
Byproducts of the liver's breakdown of toxic chemicals are discharged into the bile or blood.
By-products of bile enter the intestine and depart the body as feces. The kidneys filter out blood
waste materials, which then leave the body as urine.
