Questions Related to liver

Simple absorbable forms are produced by secretions of all except

  1. Hepatocytes

  2. Enterocytes

  3. Parietal cells

  4. Oxyntic cells

Show answer
Correct Option: A

Meat does not contain much glycogen because 

biology digestive system of human digestive glands liver pancreas

  1. It is stored only in liver

  2. Animals do not store much glycogen

  3. It is degraded by enzymes immediately after death

  4. Clinical death is not biological death

Show answer
Correct Option: A
Explanation:
Meat does not contains much of glycogen as all the excess glucose present in body is converted to glycogen and is stored in the liver.
Some of the glycogen is stored in muscle but is as less as $1-2\%$. Major portion, i.e., $100-120$gm of glycogen is stored in liver cells and are released and broken down when needed.

Bilirubin is the breakdown product of

biology digestive system of human digestive glands liver pancreas

  1. Haemoglobin

  2. RBC

  3. WBC

  4. Platelets

Show answer
Correct Option: A
Explanation:

The dead RBCs are metabolised in the spleen and liver and the heme is broken down into bilirubin which is a yellow coloured pigment.

So, the correct option is 'Haemoglobin'.

Removal of the pancreas impairs the breakdown of

  1. lipids and carbohydrates only

  2. lipids and proteins only

  3. lipids, proteins and carbohydrates

  4. proteins and carbohydrates only

Show answer
Correct Option: C

The function of the liver is to

biology digestive system of human digestive glands liver pancreas

  1. Promote digestion of food

  2. Promote respiration

  3. Store glucose as glucogen

  4. None of these

Show answer
Correct Option: C

The cells which occupy only 5% of the islets are known as 

biology digestive system of human digestive glands liver pancreas

  1. Alpha cells

  2. Beta cells

  3. Gamma cells

  4. Both of the above

Show answer
Correct Option: C
Explanation:

The islets of Langerhans are the cells in the pancreas. These cells are responsible for the endocrine functions of the pancreas. There are three type of cells, alpha cells, beta cells and gamma cells. The gamma cells are known delta cells. These cells comprise only 5% of the islets cells. These cells are responsible for the production of somatostatin hormone.

Thus, the correct answer is option C. 

Acini cells are

biology digestive system of human digestive glands liver pancreas

  1. Endocrine

  2. Exocrine

  3. Both endocrine and exocrine

  4. None of the above

Show answer
Correct Option: B
Explanation:

There are two types of cells in the pancreas, the acinar cells and the islet of Langerhans. The acinar cells are lobed cells. These cells are responsible for the exocrine function of the pancreas. They secrete the pancreatic enzymes and forms the pancreatic juice which is involved in the process of digestion.

Thus, the correct answer is option B. 

Pancreas are derived from 

biology digestive system of human digestive glands liver pancreas

  1. Ectoderm

  2. Endoderm

  3. Mesoderm

  4. All of the above

Show answer
Correct Option: B
Explanation:

In organogenesis, cells of the three germ layers lead to the formation of specific structures. The ectoderm eventually forms the outer layer of the skin and gives rise to the nervous system and sense organs. Tissues that eventually line the digestive tract and organs like liver, pancreas and lungs are all of endodermal origin. Skeletal tissue, muscle, and the circulatory, excretory, and reproductive systems are derived from mesoderm.

Thus, the correct answer is option B.

Which of the following data can be related to pancreas?

biology digestive system of human digestive glands liver pancreas

  1. It is 3 to 9 cm in breadth

  2. It is 10-23 cm in length

  3. It extends up to spleen in the abdominal cavity

  4. All of the above

Show answer
Correct Option: D
Explanation:
The pancreas is about 10-23 cm in length, 3-9 cm in breadth and 6 inches long and sits across the back of the abdomen, behind the stomach. It extends laterally and superiorly across the abdomen from the curve of the duodenum to the spleen. It is considered as heterocrine gland.
So, the correct answer is option D.

Pancreas has double role of

biology digestive system of human digestive glands liver pancreas

  1. Storage and digestion

  2. Digestion and absorption

  3. Digestion and endocrine activity

  4. None of the above

Show answer
Correct Option: C
