Lab Blood
Granulocytes
neutrophils, eosinophils, basophils
contains granules
granulocytes
monocytes, lymphocytes
Agranulocytes
does NOT contain granules
agranulocytes
Neutrophils
most numerous WBCs (60-70%)
pinkish cytoplasm
neutrophils
major phagocytes in body
neutrophils
principal role is to fight bacteria infecions
neutrophil
Eosinophils
large red granules
numbers increase w/ parasitic infections
Eosinophils
key role in allergies and asthma
eosinophils
large blue histamine granules
basophils
lowest number of WBC
Basophils
increase in numbers in anaphylaxis
Basophils
important role in inflammatory repsonse
Basophils
Monocytes
fixed phagocytes
3-8% of WBC
Monocytes
numerous in peripheral tissue
monocytes
Lymphocytes
do NOT have granules or phagocytize
non specifice defenders; increase in numbers indicates an acute viral infection
Lymphocytes
moves along lymphoid tissues, lymph nodes and blood
Lymphocytes
Hematocrit
40-45%; mass volume of RBC's in blood
Blood
Transportation; O2, CO2
homeostasis; pH levels, CO2 levels
Blood
Protection; clotting, immune sytem
Blood
Albumin (plasma protein)
normal level 3.9 to 5.0 g/dL
synthesized in liver; contributes to blood viscosity
albumin (plasma protein)
body's ability to maintain BP; carrier molecule
Albumin (plasma protein)
Fibrinogen (plasma protein)
plays a role in blood clotting
Globulins (plasma protein)
control osmosic BP; carrier molecules; role in disease resistance
Hemoglobin
protein molecules in RBC's
consist of 4 globulin proteins, each having an iron atom in the center of heme
hemogloblin
fumction is to carry CO2 and O2
Hemoglobulin
Heme (hemoglobulin structure)
a prosthetic group that consists of an iron atom in the center of a large heterocylic organic ring called prophyrin
Serum
liquid that remains after the blood has clotted
Plasma
liquid that remains when clotting is prevented
Anemia
condition of insufficent RBC's or hemoglobulin; low iron intake, hemolysis, autoimmune disease, blood loss or lack of production in bone marrow
Platelets
short life (5 to 9 day)
little specks amongst RBCs; promote blood clotting
platelets
RBC's (erythrocytes), WBCs (leukocytes), platelets (thrombocytes)
Formed elements of blood
Type A
RBC- A antigent, Plasma: Anti B antibody
Type B
RBC: B antigen plasma; Anti-A antibody
Type AB
RBC: Neither A nor B antigen Plasma: both anti A and anti B antibodies
Polycythemia
blood disorder with an increase of RBCs in blood
Thrombocytopenia
lower than normal platelet count
