CIRCULATORY, INFLAMMATORY and NEOPLASTIC LESIONS IN MEAT Flashcards
the obstruction of the blood supply to an organ or region of tissue, typically by a thrombus or embolus, causing local death of the tissue.
infarction
presence of excess fluids in tissue spaces
edema
is the lodging of an embolus, a blockage-causing piece of material, inside a blood vessel. T
embolism
is seen at slaughter in various organs, mucous and serous membranes, skin, subcutaneous tissue and muscles. It may be caused by trauma, acute infectious diseases or
septicemia.
hemorrhage
are frequently found on antemortem and post-mortem examination in food producing animals and poultry
bruises
is a localized collection of pus separated from the surrounding tissue by a fibrous capsule.
abscess
is a common condition of food animals and is characterized by a loss of fat and flesh following the loss of appetite, starvation and cachexia. It is associated with gradual diminution in the size of organs and muscular tissue as well as edema in many cases.
emaciation
is the accumulation of excess fluid in the intercellular (interstitial) tissue compartments, including body cavities.
edema
There are two types of edema:
- Inflammatory edema (exudate)
- Non-inflammatory (transudate)
shows yellow, white or greenish clear or cloudy fluid in the area of inflammation.
Inflammatory edema (exudate)
is an accumulation of fluid in subcutaneous tissue,
submucosae, lungs and brain.
Non-inflammatory edema (transudate)
is a form of edema of the subcutaneous tissues.
anasarca
is an accumulation of fluid in the peritoneal cavity.
ascites
may accompany traumatic pericarditis, ascites, cirrhosis of the liver and round worm infestation in
hydrothorax
in animals is associated with some disease conditions and is caused by an obstruction to the outflow of a air or by extensive gasping respiration during slaughter procedures.
emphysema
is an abnormal mass of tissue which grows without control and uncoordinated with the tissue or organs of origin or those nearby
tumor
is the deposition of calcium salts in dead and degenerating tissue. It may be regarded as a body reaction to immobilize some foreign agents
calcification
implies the change of tissue to a lower or less functionally active form or deterioration (impairment) of an organ or cell due to changes in its size.
degeneration
is an accumulation of fat in the heart, liver, kidneys, pancreas, etc. The liver is yellow, soft in consistency, has round edges, dimples on pressure, is enlarged and has a greasy texture on cut surfaces
fatty infiltration
is an irreversible process and occurs when fat accumulates in the damaged cell.
fatty degeneration
The liver lesions are bluish black and irregular with depressed surfaces and dilated blood filled hepatic
sinusoids. A cause of hepatic telangiectasis in cattle is thought to be local ischemia
Telangiectasis (“Plum pudding”)
