Granulocyte and Agranulocyte

Question 1:  Which type of stain is used to detect Eosinophils?

Answer:

Acidic stain, H&E-stain, Congo red stain.

Question 2: Why agranulocytes are showing large nuclei?

Answer:

Agranulocytes are showing large nucleus due to unnoticable granules are present in cytoplasm.

Question 3: What does immature granulocyte indicate?

Answer:

The early stage of infection in blood represents by immature granulocyte.

Question 4: What is the function of lymphocytes?

Answer:

Lymphocytes are part of acquired immunity. They produce antibody and kills the infected cell of the body.

The first line of defense in the human body is WBCs which are also known as leukocytes are the cells of the immune system. It circulates throughout the blood and lymphatic system. Leukocyte plays important role in the immune system by identifying, destroying, and removing pathogens and damaged cells. These cells can leave blood cells and migrate through body fluids. Leukocytes originate in the bone marrow and circulate in lymph nodes.  Leukocytes can be characterized by the presence and absence of granules (Sacs containing digestive enzymes or other chemical substances) in the cytoplasm. If there is the presence of granules are granulocytes and if there absence of granules they are called agranulocytes.  Granulocytes include Eosinophile, Neutrophiles, and basophils. Agranulocytes are monocytes and lymphocytes.
