Question: Hemoglobin
Answer: This molecule transports oxygen from the capillary beds of the lungs to the body tissues
Question: Oxygen saturation
Answer: The ratio of oxygen bound to hemoglobin Measured with a pulse oximeter
Question: 2,3 DPG
Answer: This enzyme stimulates oxygen release from hemoglobin when blood pH is low (hypoxic/acidotic).
Question: Carboxyhemaglobin
Answer: Hemoglobin disorder in which hgb has a higher affinity for carbon monoxide than for oxygen. The
Oxygen-Hemoglobin curve shifts left, patient is hypoxemic, and blood appears bright red.
Question: Methemoglobin
Answer: Hemoglobin disorder in which the iron molecule of hgb is oxidized into Fe+3, causing a left shift in the
Oxygen-Hemoglobin curve. Blood becomes brown colored.
Question: Erythropoiesis
Answer: The production and formation of red blood cells
Question: Reticulocyte
Answer: The stage of red blood cell development just prior to maturation
Question: Metarubricyte
Answer: A red blood cell more immature than a reticulocyte
Question: Rubriblast
Answer: The most immature stage of red blood cell development
Question: Leukocytosis
Answer: Medical term for an increase in white blood cells
Question: Leukopenia
Answer: Medical term for a decreased number of white blood cells
Question: Neutrophil
Answer: Granulocyte that functions in phagocytosis, secretion of mediators of inflammation, antibacterial
properties, and microbiocidal action
Question: Eosinophil
Answer: Granulocyte that functions in phagocytosis, parasiticidal action, and allergy reactions
, Question: Basophil
Answer: Granulocyte that functions in inflammation and parasiticidal action, and release histamines
Question: Circulating pool
Answer: Consists of freely moving neutrophils, this is the pool sampled from when blood is drawn
Question: Marginal pool
Answer: Consists of neutrophils that are "stuck" to the walls of small vessels Neutrophils from this pool will be
sampled more often in a stressed animal
Question: Heterophil
Answer: Neutrophils in other species that are elongated and have red staining granules
Question: Band neutrophil
Answer: Immature neutrophil that is slightly darker staining and with a horseshoe shaped, symmetrical nucleus
with rounded ends
Question: Left shift
Answer: An increase in band neutrophils in the peripheral blood, resulting from an increased demand for
neutrophils due to infection.
Question: Barr body
Answer: Represents a remnant of the X chromosome and indicates the animal is female Small protrusion on
the nucleus of a neutrophil
Question: Lymphocyte
Answer: An agranulocytic leukocyte that normally makes up a quarter of the white blood cell count but
increases in the presence of infection Only leukocyte that recirculates
Question: B cell
Answer: A type of lymphocyte that produces antibodies
Question: T cell
Answer: A type of lymphocyte that produces lymphokines, the mediates of cellular immunity
Question: Lymphoblast
Answer: An immature lymphocyte that should never be seen in the circulating blood -- usually indicates cancer
is present in the patient.
Question: Monocyte
Answer: An agranulocytic leukocyte that performs phagocytosis to fight infection The largest leukocyte, has a
very irregular nucleus and sometimes contains vacuoles
Question: Macrophage
Answer: Monocyte that migrates from the blood to tissue spaces
