Question

What is the weight of the human liver?

Answer 1

Hint: The liver is the largest gland in the human body,it is situated in the abdominal cavity, just below the diaphragm. It is reddish-brown in color,it regulates most chemical levels in the blood, it secretes bile which helps in digestion and this bile is stored in a sac-like structure called the gallbladder.

Complete answer:
The liver has two lobes i.e right and left lobes.
It takes up most of the space under the ribs and some space under the upper left abdomen.
In an adult human body, the weight of the liver is about 1.2 to 1.5 kg.
The weight of the liver shows variation between men and women and among different individuals.
In men, it weighs approximately 1kg-1.8kg whereas in women it weighs approx 0.6 kg to 1.7 kg.
The size of liver depends on several factors: age, sex, body size, and shape.
Hepatic lobules are the structural and functional units of the liver containing hepatic cells arranged in the form of cords.
Each lobule is covered by a thin connective tissue sheath called Glisson’s capsule.
Glisson's capsule is the characteristic feature of the mammalian liver.
The mammalian liver also contains Kupffer cells that are phagocytic cells and eat worn-out WBC's, RBC's and bacteria.
The hepatic cells secrete bile and are transported to the gallbladder through hepatic ducts.
The liver receives blood supply from two sources- the hepatic portal vein and hepatic arteries. The hepatic portal vein delivers about $75\%$ of the liver's blood supply and carries venous blood drained from the spleen, gastrointestinal tract, and its associated organs.
The liver plays a major role in carbohydrate, protein, amino acid, and lipid metabolism.

Note:
Liver also produces a protein called angiotensinogen which indirectly regulates the reabsorption of sodium ions from the filtration through distal convoluted tubeless.The weight of the liver may vary in different individuals, during the developmental stage liver size increases with increasing age.
