VN 134 VETERINARY IMMUNOLOGY
EXAM 1 QUESTIONS AND ANSWERS
Integument system - Correct Answers -skin surface normal flora-recognizes and
destroys potential invaders. physical barrier-protects internal organs. Acidic pH and fatty
acid content prevent bacterial growth.
Red bone marrow - Correct Answers -contains pluripotent stem cells which develop into
the lymphoid progenitor or common myeloid progenitor.
Thymus - Correct Answers -located in mediastinum. T lymphocytes mature here prior to
migration into other lymphoid tissues. Large in young animals, atrophies as animal
ages.
spleen - Correct Answers -white pulp-contains lymphoid tissue
red pulp-specialized blood-filled sinuses which removes worn, damaged or aged blood
cells via macrophages.
acts as reservoir for additional blood supply.
lymphatic system - Correct Answers -responsible for collecting and returning excess
interstitial tissue fluid to the cardiovascular system.
lymph vessels - Correct Answers -parallel the vessels of the circulatory system.
lymphatic capillaries - Correct Answers -drain excess fluid as lymph into lymphatic
vessels, drain into thoracic duct and into the systemic circulation in the area of the right
atrium.
chyle - Correct Answers -lymph collected from the GI tract
lymph nodes - Correct Answers -structures located throughout the body that filter lymph
palpable peripheral nodes - Correct Answers -submandibular, prescapular, axillary,
inguinal, popliteal
MALT(mucosa associated lymphatic tissue) - Correct Answers -clusters of lymphoid
tissue located near mucosal surfaces that identify antigens and mount an immune
response against them. Include tonsils and peyers patches.
, CALT - Correct Answers -conjunctive associated lymphatic tissue
NALT - Correct Answers -Nasopharynx Associated Lymphatic Tissue
GALT - Correct Answers -gut associated lymphoid tissue
tonsils - Correct Answers -found in pharynx, larynx, urinary and reproductive systems,
contain lymphocytes.
peyer's patches - Correct Answers -fount in cattle, sheep, pigs, horses and dogs. mainly
ileum but some in jejunum.
immunology - Correct Answers -study of the immune system
imune system - Correct Answers -the cells, tissues and organs that protect the body
from disease
innate or nonspecific immunity - Correct Answers -the immunity with which we are born.
including physical and chemical barriers, skin, respiratory tract, GI tract, urogenital tract,
mammary gland, ocular mucosa
phagocytes - Correct Answers -the body's first line of defense
leukocytes activated as a back-up mechanism - Correct Answers -neutrophils and
macrophages, dendritic cells, mast cells, specialized population of T lymphocyte cells
residing in the epithelial barriers.
key features of innate immunity - Correct Answers -immediate, no specificity, no
memory, weak and may not last long
clinical signs of innate immunity - Correct Answers -histamine release of mast cells,
swelling or edema, redness and excessive heat, release of extra mucus.
inflammation - Correct Answers -the collective effect of the molecules and cells of the
innate immune system in responding to insult by pathogens, trauma, or local immune
response
inflammatory response - Correct Answers -accumulation of fluid, plasma proteins and
blood leukocytes at the site of such insult.
goal of inflammatory response - Correct Answers -neutralize the cause, contain
pathogens, prevent systemic spread to promote tissue repair once the pathogen is
eliminated.
acute inflammation - Correct Answers -begins within minutes of tissue insult
pain, swelling, heat, redness, loss of function of the affected tissue
