Erythrocytes
Platelets
Leukocytes
Separation of Blood Components
Centri = center
Centrifuge activity: vial, pencil, string, dirty water
Buffy Coat
Pg 299
Leukocytes = white blood cells
immunity
Platelets = clotting
Buffy Coat
The layer produced by these
two types of blood elements is
called the “Buffy Coat.”

Leukocytes:
Buffy Coat
Leuko = white
Cyte = cell
1. Neutrophils = phagocytes
2. Eosinophils = kills worms,
fights allergies, neutralizes
harmful chemicals
3. Basophils = contain
histamine to fight allergies
and inflammation.

Pg 299
Leukocytes:
4. Lymphocytes = immunity
B-cells: produces antibodies
T-cells: fights tumors and viruses
and activate B-cells
Pg 299
Leukocytes:
5. Monocytes = phagocytes that
become macrophages
“Clean-up Team” = digests larger
cells.
Mono = one
Pg 299
Erythrocytes = red blood cells (RBCs)
carries oxygen
Hemoglobin = part of erythrocyte that
bonds to carries the oxygen and also
can transport CO2 waste away
erythro = red
Occurs in bone marrow.
Hemocytoblast = stem cell for blood
Erythropoietin = hormone controlling the production of
blood cells.

BLOOD
Blood cells
have antigens
and
antibodies.
Antibodies are what
the cell doesn’t like
(which is anything
different from the
“type.”)
Antigens are
tiny receptors
on the
outside of the
blood cell that
matches the
“type.”

or
Rh comes from the rhesus monkey in which the factor
was originally identified.
Rh+ means the RBCs carry the Rh antigen.
If an Rh- person receives Rh+ blood, their immune
system will react to the transfusion and the patient’s
antibodies will attack and kill the new blood cells.
How could an Rh+ woman became pregnant with an Rhbaby and what would happen to the baby?
Bleeding Disorders
Thrombocytopenia = not enough platelets to clot.
Liver can’t produce clotting factors due to lack of
Vitamin K.
Hemophilia = several inherited bleeding diseases
“Free bleeder”
No platelets are present.
