Question

In man, the gall bladder is situated in the _____ lobe of the liver.
A. Left
B. Right
C. Caudate
D. Quadrate

Answer 1

The human digestive system consists of many essential organs. Apart from these main organs it also consists of some accessory organs like salivary glands, liver, gallbladder, and pancreas. The liver performs the major metabolic functions of the body. When the acidic food (chyme) enters the small intestine from the stomach it is neutralized by pancreatic secretions and the bile juice which is produced by the liver. This bile juice plays a very important role in the whole digestion process.

Complete answer:
The human liver is a lobulated structure consisting of two major anatomical lobes namely- right and left lobes. Along with these caudate lobes and quadrate lobes are also present in the liver. The abdominal region is divided into several quadrants and regions. The left lobe of the liver is situated in the left hypochondriac and the epigastric region of the abdomen. It is closely associated with the diaphragm and stomach. The right lobe of the liver is greater than the left lobe and is situated in the right upper quadrant of the abdomen. It is closely associated with the gallbladder, portal vein, and inferior vena cava.
The gallbladder is a very small bag-like structure closely associated with the right lobe of the liver. It is the storage house of the bile juice. Also, it is responsible for the concentration of bile juice. The caudate lobe of the liver is found on the postero inferior surface of the right lobe of the liver and the quadrate lobe is found inferior to the left lobe of the liver.

Thus the correct answer is option B.

Note:
Bile is secreted continually by the liver cells, but most of it is normally stored in the gallbladder until it is needed in the duodenum. Its major function is the breakdown of large fat molecules (emulsification). Bile does not contain any digestive enzyme so it is called false digestive juice. The major composition of bile juice is the alkaline salts present in it like sodium bicarbonate, sodium glycocholate, and taurocholate salts.
