Answer 1

Blood is composed of formed element and plasma. Formed elements are composed of RBC, WBC and platelets. RBC - Red Blood Cells are also called erythrocytes and are unnucleated in when mature. In RBC haemoglobin is present and which responsible for oxygen transport. WBC may me myeloid or lymphoid origin. In lymphoid there are B Cell, T cell and NK cells. B cells are the white blood cells which are involved in acquired immunity and functions are specific in nature. T Cells are also specific and involed in acquired immunity. These release cytokines. NK cells are also called null cells and require Presence of MHC 1 for detection of healthy cells and if MHC 1 is absent they release their granular content.

PMNLs - These are also called granulocytes. And these are Neutrophil - having receptor for IgG, basophill - having receptor for IgE and Eosinophil - having receptor for both IgE and IgG and all these cells have granules which may have primary and secondry mediators and Granzyme B.

Monocytes are the undifferentiated cells in blood and differentiated into macrophage or dendritic cell in tissue region.
