What is the formation of white blood cells?
Blood is a fluid connective tissue that contains plasma and three types of blood corpuscles namely erythrocytes, leucocytes, and thrombocytes. Leucocytes (white blood cells or WBCs) do not have hemoglobin and are od two types: agranulocytes and granulocytes.
The formation of white blood cells is known as leucocytosis or leucopoiesis.
Agranulocytes lack granules and the nucleus is not lobed. There are two types of agranulocytes lymphocytes and monocytes. Lymphocytes are formed in lymph nodes, spleen, thymus, tonsils, bone marrow, Peyer's patches. Monocytes are formed in bonemarrow only.
Granulocytes contain granules in their cytoplasm and have a lobed nucleus. There are three types of granulocytes eosinophils, basophils, and neutrophils. All three of them are formed in the bone marrow.
