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

of oxygen; one hemoglobin molecule can transport 4

molecules of oxygen

TERM 10

Granulocyte

DEFINITION 18

white blood cells with granules (neutrophiles, eosinophiles,

and basophils).

TERM 19

Phagocytic

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

Chronic Leukemia

occurs later in WBC formation pathway; doesn't affect as

many cells since it occurs later in cycle; much slower

developing; usually in adults

TERM 22

Agranulocyte

DEFINITION 22

WBC that doesn't contain granules (lymphocyte, monocyte)

TERM 23

Defensin

DEFINITION 23

antiobiotic-like proteins in neutrophiles (bacteria fighters)

TERM 24

Neutrophil

DEFINITION 24

2 types of granules that take up acids and bases, lilac color,

bacteria fighters, contain defensins

TERM 25

Histamine

DEFINITION 25

inflammatory protein that acts as a vasodilator and attracts

other WBCs

Petechiae

red/purple spot on body caused by minor hemorrhage
