How many lobes of the liver are present in a rabbit?
A. 2
B. 4
C. 5
D. 6

Hint: In mammals, the liver is an organ that performs numerous functions. It is a glandular organ, which has multiple secretions, which would help in the process of digestion. It is also the main center in the process of detoxification in the body.

Complete Answer:
The liver is a lobed organ. And the rabbit liver is made up of four lobes. The main lobes present are the caudate lobe and three cranial lobes which are single and the left lobe is separated into two regions, the medial and the lateral. The liver is associated with a sac-like structure known as the gallbladder which is cylindrical in rabbits, and it stores and secretes the pigments synthesized by the liver.
Considering the other given options above:
The liver consisting of two lobes is known as the bilobed liver. The liver consisting of two lobes are present in primates such as human beings. These lobes then get connected by small ducts, which later join together to form a large hepatic duct for the transport of substances. The liver is made up of cells known as the hepatocytes, therefore option A is not the correct answer.
The liver made up of six lobes is present in mammals such as dogs. D is also not an appropriate answer.

Thus the most appropriate answer for the question from the options given above is B, that is, the liver of a rabbit is made up of four lobes.

Note:The liver is the only organ that has the ability of regeneration. The organ produces new hepatic cells constantly to replace the damaged cells. Any disease related to the liver occurs when the organ fails to replace the affected cells and it leads to an accumulation of fibers in the organ replacing the functioning cells.
