Question

The structural and functional unit of liver are called
A. Glisson’s capsule
B. Hepatic cells
C. Hepatic cords
D. Hepatic lobules

Answer 1

Hint: Our body consists of many organs that function together to make us survive. Every organ has a specific function. The storing and break-down of substances like protein and fats are carried out by the liver.

Complete Answer:
- The liver is the largest organ of the human body. It is a very important part of the body that involve in immune system and metabolic functions. The liver is located in the right upper part of the stomach below the diaphragm.
- A part of the liver goes to the upper left of the abdomen also. It is half moon shaped and slightly tilted in the cavity of the body with the left part of the stomach and the right part above the first part of the small intestine. It is composed of two lobes that are divided further into eight segments.
- Each of the segments has approx 1,000 lobules or lobes. Each lobule has small ducts that move towards the common hepatic duct, the liver has a large amount of blood flowing through it compared to other body parts. The liver is involved in the conversion of substance into simple substance, extract energy, and remove toxins from the bloodstream.
- The liver carries out this function by receiving blood with nutrients from the digestive organs through the portal vein. Hepatocytes are the cells found in the liver involved in accept and filtration of blood.
- They act as a sorting center where, which nutrient to be processed, what to store, what to be eliminated, and what to go back into the blood is determined. The liver is involved in the storage of vitamins and minerals like iron and copper.
- Now, as mentioned above the structural and functional unit of a liver is hepatic lobules. That involves the break-down of proteins, fats, alcohol etc and stored minerals, vitamins, and other substances. These substances are released whenever our body needs them.

Thus, the correct answer is ‘D’. Hepatic lobules.

Note: Beside all the function like break-down of substance and storing of substance liver also play a very important role in the creation of immune system factors that involve in fight against the infection, produce proteins that involve in the blood clotting process, break-down the damaged and old blood cells, and also involve in the sorting of extra sugar in blood as glycogen.
