DEFINITION 2
process by which red blood cells are produced
TERM 3
hemorrhagic
DEFINITION 3
blood loss
TERM 4
hematocrit
DEFINITION 4
fraction of blood that is occupied by RBCs
TERM 5
Hemoglobin
DEFINITION 5
protein with 4 subunits; have a heme group which
coordinates an oxygen to bind with the iron.
Hematopoeisis
formation of blood cellular components
TERM 7
Hemolytic
DEFINITION 7
rupturing of erythrocytes and the release of their contents
into surrounding fluid
TERM 8
Erythropoeitin
DEFINITION 8
hormone produced by the kidneys that stimulates the
formation of red blood cells in the bone marrow
TERM 9

DEFINITION 19
cellular process of engulfing solid particles by cell membrane
to form phagosome
TERM 20
Acute Leukemia
DEFINITION 20
cells early in formation process; high capacity for cell
division; overrun bloodstream and marrow; seen in children

TERM 23
Defensin
DEFINITION 23
antiobiotic-like proteins in neutrophiles (bacteria fighters)
TERM 24
Neutrophil
DEFINITION 24

bacteria fighters, contain defensins
TERM 25
