New cards

Monocyte

 “Kidney-shaped” or “bean-shaped”

 Largest of the formed elements
o Bigger than the RBC

 Cytoplasm is more abundant and has a grayish blue tint

 They stay in the circulation for an average of 72 hours before they are deposited in the tissue and are converted to macrophages
