Question

The specific function of liver is
A. Excretion
B. Digestion
C. Histolysis
D. Glycogenesis and Glycogenolysis

Answer 1

Hint: It is the only visceral organ that can regenerate. It can regenerate completely, as long as a minimum of 25 percent of the tissue remains. It also plays the critical role in synthesizing molecules that are utilized elsewhere to support homeostasis.

Complete Answer:
The liver is a large organ that is located on the right side of the belly. Its weight is about 3 pounds and is reddish-brown in color and feels rubbery to the touch. Generally you can't feel the liver, because it is protected by the rib cage.

- Option A is incorrect as excretion takes place by anus.
- Option B is incorrect as digestion takes place in the stomach and small intestines.
- Option C is incorrect as it is the breaking of animal tissues and it also does not occur in the liver.
- Option D is correct as hepatocyte/liver plays a significant role in glucose production process by balancing the uptake and storage of glucose via gluconeogenesis (the process of glycogen synthesis) and the release of glucose via glycogenolysis (the breakdown of glycogen to glucose-1-phosphate and glucose) and gluconeogenesis (generation of glucose from noncarbohydrate carbon substrates such as pyruvate, lactate, glycerol, and glucogenic amino acids).

So, the correct answer is option (D) i.e., Glycogenesis and Glycogenolysis.

Note: A layer of fibrous tissue called Glisson’s capsule covers the outside of the liver. This capsule is covered by the peritoneum membrane, which forms the lining of the abdominal cavity. This helps hold the liver in place and protects it from any kind of physical damage.
