Donation Facts
Hematology
Study of blood
Plasma
Liquid portion of blood
Erythrocyte
Red cell
Function of Erythrocytes
Transport oxygen and carbon dioxide
Leukocyte
White blood cell
Function of Leukocytes
Protect the body against infection and disease

Complete Blood Count
Purpose of a CBC
To evaluate overall health and detect disorders like anemia or infection
Granulocytes
, Neutrophils, Eosinophils, and Basophils
Agranulocytes
Monocytes (Macrophages) and Lymphocytes
Chemicals released by Basophils
Histamine and Heparin
Neutrophil
Cell with a multi-lobed nucleus and granules
Monocyte
Large agranulocyte that becomes a macrophage
Elevated Leukocyte count indicates
An infection or Leukemia
Most common blood disorder
Anemia (specifically Iron Deficiency Anemia)
Blood disorder with crescent-shaped cells
Sickle Cell Anemia
Cancer of the leukocytes
Leukemia
Leukocytes carry oxygen
False
Antigens
