Consider the following statement: Heart is the largest gland in the...
The correct answer is option 'C': 3 and 4 only. Let's break down each statement and explain why they are correct or incorrect.
1. Heart is the largest gland in the human body.
This statement is incorrect. The heart is not a gland; it is a muscular organ that pumps blood throughout the body. Glands are organs that produce and secrete substances, such as hormones or enzymes. Therefore, statement 1 is incorrect.
2. Gall bladder is responsible for secretion of bile in the human body.
This statement is correct. The gall bladder is a small organ located below the liver. Its primary function is to store and concentrate bile, a digestive fluid produced by the liver. When food is consumed, the gall bladder contracts and releases bile into the small intestine to aid in the digestion and absorption of fats. Therefore, statement 2 is correct.
3. The pancreas is a both exocrine and endocrine organ of the human body.
This statement is correct. The pancreas has both exocrine and endocrine functions. As an exocrine organ, it produces digestive enzymes that are released into the small intestine to help break down carbohydrates, proteins, and fats. As an endocrine organ, it produces hormones, including insulin and glucagon, which regulate blood sugar levels. Therefore, statement 3 is correct.
4. The liver is the only organ in the human body that can regenerate itself.
This statement is correct. The liver has the remarkable ability to regenerate itself. When a part of the liver is damaged or removed, the remaining liver tissue can regenerate and restore its full function. This regenerative capacity is due to the presence of hepatic progenitor cells, which can differentiate into hepatocytes, the main functional cells of the liver. Therefore, statement 4 is correct.
In conclusion, the correct statements are:
- Gall bladder is responsible for secretion of bile in the human body.
- The pancreas is a both exocrine and endocrine organ of the human body.
Therefore, the correct answer is option 'C': 3 and 4 only.
Consider the following statement: Heart is the largest gland in the...
Option c is correct.
- Statement 1 is incorrect: Liver is the largest gland of the body weighing about 1.2 to 1.5 kg in an adult human. It is situated in the abdominal cavity, just below the diaphragm and has two lobes. On the other hand, average weight of heart is 250- 300 gm.
- Statement 2 is incorrect: Liver is responsible for production of a digestive fluid known as bile. Liver releases Bile into Gall Bladder which is a small, pear-shaped organ located just below your liver in the upper right side of your abdomen.
- Statement 3 is correct: The pancreas is a both exocrine and endocrine organ of the body. The pancreas has the dual function of secreting hormones into blood (endocrine) and secreting enzymes through ducts (exocrine).
- Statement 4 is correct: The liver is the only organ in the human body that can regenerate. After the diseased portion of the liver is removed, fibrinogen and blood platelets accumulate in the remaining liver, which triggers the earliest stages of regeneration.
