Question

Read the following statements regarding liver:-
A) Hepatic lobules are structural and functional units of liver.
B) Liver secretes bile, which contains digestive enzyme
C) Each hepatic lobule is covered by a thin epithelial tissue, called "Glisson's capsule"
D) Hepato-pancreatic duct is guarded by the sphincter of Boyden.

Answer 1

The hepatic lobules act as building blocks of the liver. Hepatic lobules act as small scales like division of the liver. Bile salts help in emulsification of fats which is breakdown of fat into smaller units.

Complete answer:
The correct answer is A and B. The reason only A and B are considered correct is that it is true that hepatic lobules are structural and functional units of the liver.Like in our frame the structural and purposeful unit is a cell. The liver is actually organized into lobules and The lobules of liver form the chief mass of the hepatic substance
Bile is the digestive juice which is secreted by the liver. Although it does not contain any digestive enzyme in itself but since it helps in emulsification of fats it is a very important secretion.Bile juice has bile pigments including bilirubin and biliverdin. These pigments break down big fats globules into smaller globules in order that the pancreatic enzymes can without problems act on them. Bile juices also activates lipase.Glisson's pill does paperwork a layer of connective tissue surrounding the liver and it additionally ensheaths the hepatic artery, portal vein, and bile ducts within the liver but as given in option (c) that hepatic lobule is covered by a thin epithelial tissue, called Glissons’s capsule is wrong.
Sphincter of Boyden helps in filling the gallbladder and it surrounds the bile duct. Therefore, as given in option (D) it is not correct.

Hence options A and B are the correct answer.

Note: The liver is located in the right upper quadrant of the abdomen, below the diaphragm.It is an organ which can only be found in vertebrates.It detoxifies numerous metabolites, synthesizes proteins and produces biochemicals vital for digestion and growth.
