Question

Identify the white blood cells which increase during allergy.

• A. Monocytes.
• B. Platelets.
• C. Neutrophils.
• D. Eosinophils.

Answer 1

The correct option is D

Eosinophils.

The correct option is D:
Explanation of the correct option:

1. A white blood cell called Eosinophil is a granulocyte, which means it secretes enzyme granules to combat foreign invaders and illnesses. Eosinophils are involved in nearly every bodily system.
2. The immune system is involved in two of their most critical roles.
3. The first is to eliminate invading pathogens including parasites, bacteria, and viruses.
4. The second in inflaming the body.
5. This procedure helps the body maintain in identifying and controlling an illness or allergic reaction.
6. A high number of eosinophils is called eosinophilia, caused by nasal allergy or more serious conditions like cancer, it can be detected by blood testing.

Explanation of the incorrect options:

Option A:

1. Monocytes make up about 1% to 10% of all white blood cells.
2. These immune cells circulate in the blood for several days before becoming macrophages or dendritic cells in the tissues.
3. They are one of the most common white blood cell types. Each white blood cell has a particular function that influences adaptive immune responses. Monocytes are immune cells that protect the body from viral, bacterial, fungal, and protozoal diseases. Phagocytic cells are monocytes.

Option B:

1. Platelets also called as thrombocytes are blood cells formed in the bone marrow. They begin as pinched-off fragments of bigger cells in the bone marrow. Platelets are neither smooth or spherical, but rather have the appearance of shredded paper. They spend a lot of time in the bloodstream, sailing alongside their red and white blood cell cousins.
2. Platelets primary function is to stop bleeding when the body is injured. To seal the wound, a blood clot must be formed.

Option C:

1. Neutrophils are a type of white blood cell (WBC or granulocyte) that, among other things, defend humans from illnesses.
2. They are the most abundant type of granulocytes and make up 40% to 70% of all white blood cells in humans.
3. Neutrophils are a type of phagocyte and are found in the blood stream, during the acute phase of inflammation , particularly as a result of bacterial infection, environmental exposure and some cancers neutrophils are one of the first responders of inflammatory cells to migrate towards the site of inflammation.

Final answer: The white blood cells which increase during allergy is eosinophils.
