* '''erythrocyte''' - (red blood cell) most abundant blood cell with no nucleus and cytoplasm contains haemoglobin.Cells are about 7 µm in diameter, "donut-shaped" and function to transport of oxygen. | |||
* '''eosinophil''' (eosinophil granulocyte) blood cell nucleus has two lobes and cytoplasm filled with granules that stain red or pink when eosin. Cells involved with phagocytosis of antibody-antigen complexes, granules also contain histaminase and arylsufatase to degrade histamine and leukotrienes. | |||
*'''extraembryonic mesoderm''' - mesoderm lying outside the trilaminar embryonic disc covering the yolk sac, lining the chorionic sac and forming the connecting stalk. Contributes to placental villi development. | *'''extraembryonic mesoderm''' - mesoderm lying outside the trilaminar embryonic disc covering the yolk sac, lining the chorionic sac and forming the connecting stalk.

The function of the pathway will be to alter the cell directly or indirectly by changing gene expression.

* '''monocyte''' - blood cell nucleus is C-shaped and cytoplasm slightly larger and stronger staining than granulocytes. Monocytes contain fine granules (lysosomes) and when leave the circulation and locate in tissues, differentiate into macrophages. | |||
* '''neutrophil''' (neutrophil granulocytes) - most common granulocyte blood cell nucleus divided into 3-5 lobes connected by thin strands of chromatin. Cytoplasm contains two types of granules: primary granules (A granules, lysosomal enzymes) and Secondary granules (B granules, bactericidal enzymes). | |||
