Week 10 Flashcards
colloid
a liquid that contains suspended particles (i.e. plasma)
fibrin/o
fibrin or threads of a clot
thromb/o
clot
triglyceride
a type of lipid circulating in blood
Heme
nonprotein, iron-containing portion of hemoglobin
reticulocyte
immature, non-nucleated erythrocyte. Seen in regenerative anemia
dyscrasia
any abnormal condition of the blood
edema
accumulation of blood in the intercellular space
hemolytic
removing and destroying rbc’s
hyperemia
excess blood in a part
modified transucate
seen in right side heart failure. protein concentration is greater than 2.5g/dL
myelodysplasia
hematologic disorder characterized by ineffective hematopoiesis that results in some form of cytopenia
transudate
material that has passed through a membrane and is high in fluid and low in protein, cells, or solid materials. observed with severe hepatic disease, enteropathy, or nephropathy
lymph
formed when interstitial fluid moves into the capillaries of lymphatic system. brings nutrients and hormones to cells and carries waste products from tissue back to bloodstream
cisterna chyli
origin of the thoracic duct and saclike structure for the lymph collection
tonsils
masses of lymphatic tissue that protect the nose and cranial throat
spleen
- located in cranial abdomen
- filters foreign material from blood, stores erythrocytes, removes damaged or old erythrocytes, and maintains an appropriate balance of cells and plasma in the blood.
- secondary lymphoid tissue where mature lymphocytes await antigenic stimulation
thymus
immunologic gland found predominantly in young animals. Involved in development of T cells.
T cells
Cell-mediated immunity. Directly attack invading antigen
-most effective against viruses that infect body cells, cancer cells, and foreign tissue cells
B cells
Humoral (antibody-mediated) immunity.
- produce antibodies that react with antigen or substances produced by the antigen
- most effective against bacteria, viruses that are outside body cells, and toxins.
- involved in allergic reactions
antigen
foreign substance
antibody
disease fighting protein produced in response to the presence of an antigen
helper T cells
CD4 - secrete substances like cytokines that stimulate production of B lymphocytes and cytotoxic T cells
Cytotoxic T cells
destroy intracellular pathogens
Suppressor T cells
stop B and T lymphocyte activity when it is no longer needed
Memory T cells
remember a specific antigen and stimulate a faster and more intense response next time.
histiocytes
large macrophages found in loose connective tissue
complement
series of enzymatic proteins that are continually present in normal plasma
anaphylaxis
severe, acute response to a foreign substance
lymphadenopathy
disease of the lymph nodes
lymphangioma
abnormal collection of lymphatic vessels forming a mass (usually benign)
anaplastic
reverting to a more immature form
dysplastic
abnormal cell development
follicular
containing glandular sacs
nodular
tight cell clusters
pleomorphic
having many cell types
medullary
large and fleshy
verrucous
having wart like growths
apoptosis
programmed cell death
pedunculated
having a peduncle, or stalk
metastasis
pathogenic growth distant from the primary disease site
carcinoma
malignant epithelial cells
sarcoma
malignant neoplasm arising from any type of connective tissue
-gen
producing
histopathology
microscopic study of structure, composition, and function of tissues
touch preps
collections of cells on a glass slide pressed against a part of the mass
adenocarcinoma
malignant growth of epithelial glandular tissue
blastoma
neoplasm composed of immature undifferentiated cells
hemangioma
benign neoplasm of newly formed blood vessels
hemangiosarcoma
malignant tumor of vascular tissue
leiomyosarcoma
malignant tumor of smooth muscle
myeloma
malignant neoplasm of bone marrow
myxoma
tumor of connective tissue
neuroblastoma
malignant neoplasm of nervous tissue
rhabdomyosarcoma
malignant tumor of striated muscle
fulguration
destruction of tissue by high frequency electrical current
