Blood/Hematologic System

Blood is a dynamic fluid made up of cellular and plasma components that are constantly being recycled and renewed. Like in other physiological systems, the vascular endothelium and a narrow range of anticoagulation are responsible for closely controlling the amounts of these components. The peripheral blood smear, which enables doctors to evaluate the functional status of the bone marrow during cytopenic states, is quick, trustworthy and affordable means of looking at hematological  problems
