The disease cirrhosis affects which organ in the body?

Option 2 : Liver

The correct answer is Liver.

• Cirrhosis develops when scar tissue replaces normal, healthy tissue in your liver.
• It happens after the healthy cells are damaged over a long period of time, usually many years.
• The liver is the largest gland of the body weighing about 1.2 to 1.5 kg in an adult human.
• It is situated in the abdominal cavity, just below the diaphragm.

Explanation-

• The liver has two lobes.
• The 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 the Glisson’s capsule.
• The bile secreted by the hepatic cells passes through the hepatic ducts and is stored and concentrated in a thin muscular sac called the gall bladder.
• The duct of the gall bladder (cystic duct) along with the hepatic duct from the liver forms the common bile duct.
• The bile duct and the pancreatic duct open together into the duodenum as the common hepato-pancreatic duct. 
• Pancreatic juice and bile are released through the hepato-pancreatic duct.
• The pancreatic juice contains inactive enzymes – trypsinogen, chymotrypsinogen, procarboxypeptidases, amylases, lipases, and nucleases.
• Trypsinogen is activated by an enzyme, enterokinase, secreted by the intestinal mucosa into active trypsin, which in turn activates the other enzymes in the pancreatic juice.
• The bile released into the duodenum contains bile pigments (bilirubin and biliverdin), bile salts, cholesterol, and phospholipids but no enzymes.
• Bile helps in the emulsification of fats, i.e., breaking down the fats into very small micelles.

Thereby the liver digests fats.
