Question

Which of the following statements are correct?

1. Basophils are most abundant cells of the total WBCs
2. Basophils secrete histamine, serotonin and heparin
3. Basophils are involved in inflammatory response
4. Basophils have kidney shaped nucleus
5. Basophils are agranulocytes

Choose the correct answer from the options given below:

• A. C and E only
• B. B and C only
• C. A and B only
• D. D and E only

Answer 1

The Correct Option is B

To determine which statements about basophils are correct, let's analyze each option based on biological knowledge:

1. False: Basophils are the least abundant white blood cells (WBCs), not the most abundant. Neutrophils are the most abundant.
2. True: Basophils secrete histamine, serotonin, and heparin. These chemicals play a role in inflammatory responses and allergic reactions.
3. True: Basophils are involved in inflammatory responses. They release chemicals that help mediate these responses.
4. False: Basophils have a multi-lobed nucleus, typically not kidney-shaped. Monocytes and some other cell types have kidney-shaped nuclei.
5. False: Basophils are granulocytes, not agranulocytes. Granulocytes have granules in their cytoplasm, which basophils do.

Given the analysis above, the correct answer is B and C only.

Answer 2

Statement B is correct - Basophils are a type of white blood cell (WBC) that are involved in immune responses, particularly allergic reactions. They release histamine and other chemicals like serotonin and heparin, which are important in various immune and inflammatory processes.
Statement C is correct - Basophils play a role in the body's response to inflammation, allergies, and immune responses. Their release of histamine and other substances contributes to the inflammatory reaction.
Statement A is incorrect - Basophils are actually one of the least abundant types of white blood cells.
Statement D is incorrect - Basophils typically have a multilobed nucleus, similar to other granulocytes.
Statement E is incorrect - Basophils are granulocytes, a type of white blood cell characterized by the presence of granules in their cytoplasm.

So,tThe correct option is (B): B and C only
