Question

Agranulocytes normally develop in
a. Bone marrow
b. Liver
c. Lymph glands and spleen
d. None of these

Answer 1

Hint: The blood contains various types of cells, but the main constituent of blood is made by RBC, while blood cells and the platelets, and white blood cells are also again divided into agranulocytes and granulocytes.

Complete answer:
> Among the white blood cells, there are two types of cells, which are agranulocytes, which means granules are absent on their cytoplasm, two cells comprise of agranulocytes, which include cells such as Monocytes and lymphocytes, this cells make up 35% of the hematological value.

> Lymphocytes are major cells in the part of the immune system, and this lymphocyte comprises three types of cells, which are B cells, T cells, and natural killer cells, B cells provide the antibodies to identify the antigens and to provide immunity. Whereas T cells and natural killer cells kill mainly virus attacked cells.

> Monocytes have the function of the phagocytosis and they also provide the pieces of antigens to T cells to provide the immunity, and they are also called macrophages, as they migrate from the circulatory system to the surrounding tissues and this is known as diapedesis.

> Agranulocytes are mainly produced by the leucopoiesis from the precursors of hematoblast, which all are derived from the hematopoietic stem cells in the bone marrow. And some of the agranulocytes are formed and they further develop in lymphoid organs and spleen.

Hence, the correct answer is option (C).

Note: The main function of the agranulocytes are to invade the microbes such as bacteria and virus, and to invade and remove the cancer cells in the body and to activate the immune system, and also destroying the old and damaged cells.
