Erythrocyte
Scientific Term for Red Blood Cell. Lacking both a nucleus and organelles. Filled with hemoglobin.
Leukocyte
Scientific Term for White blood cells.
Platelets
Fragments of cells. Platelets play an important role in blood clotting.
Formed Elements
Any of the non-fluid, cellular parts of blood. Formed elements include: Erythrocytes, Leukocytes and Platelets.
Plasma
Fluid Portion of Blood that contains many disolved molecules.
Neutrophil
Most common Leukocyte. Specializes in defending body against bacteria. Attracted to areas of inflammation.
Eosinophil
Leukocyte specialized for defending the body against parasitic worms.
Basophil
Least common leukocyte. Stimulate release of histamine from cells around damaged tissues.
Granulocytes
Leukocytes with a grainy texture or look to them. Include: Neutrophils, Eosinophils, and Basophils.
Lymphocyte
Leukocytes specialized for attacking/ defending against cells infected with virus or cancer.
Monocytes
Largest Leukocytes, act as macrophages against chronic infections.
Agranulocyte
Type of Leukocyte that appears smooth, not granular under microscope. Includes: Lymphocytes and Monocytes.

Hematocrit
The percentage of blood made up of erythrocytes.
ABO Blood Groups
Blood typing based on the presence or absence of antigens on the surface of red blood cells.
Type AB Blood
Has both A and B antigens on surface of red blood cells and no antibodies. Can accept blood from any blood type - "Universal Recipient."
Type O Blood
Has no antigens on red blood cell surface. Type O blood can be given to anyone - "Universal Doner".
Type A Blood
Has A antigens on cell surface and anti-B antibodies.
Type B Blood
Has B antigens on cell surface and Anti-A antibodies.
Blood pH
Blood pH is slightly basic. Around 7.4.
Albumin
