contatins hemoglobin which has iron and give RBCs and blood the red color
biconcave discs and flexible
Reticulocytes

Role of Hemoglobin
carry oxygen to cells and tissue and carry carbon dioxide away from cells and tissue
platelet characteristics
called thrombocytes
clotting cells
first step of clotting process where paltelets get "sticky" and clump together to form temporary clot
not WBC's
1st step in clotting process
clumpin(stickyness) of platelets to form temporary plug until sequence of clotting proteins can act
Final product of clotting process
production of fibrin
Hemophilia
X-linked (transmitted by mother) bleeding disorder in which a clotting proteins can act
Characteristics of WBC's
called leukocytes
five catergories
part of the body's defense system
5 types of WBC's
neutrophils
basophils
eosinophils
lymphocytes
monocytes
Characeristics of neutrophils
most numerous WBC
phagocytes
granulocyte
characterisic eosinophils
granulocyte
involved in allergic reaction
protects against parasite infections
Characteristic of basophils
granulocyte
secrete histamine and heparin
Characteristics of lymphocytes
agranulocytes
involved in production of antibodies (B lymphocytes)
and direct atack of invading cells (T lymphocytes)
Two kinds of lymphocytes
B and T
Plasma cells
mature or activated B lymphocytes
Characteristic of monocytes
largest WBC
agranulocytes
phagocytes (name mmeans largest eater)
marcrophages when enter tissue
