Name the condition Flashcards
myocardial hypertrophy
(greater contractility & ejection force)
cardiac dilation
(increased stroke volume)
cardiac dilation of both ventricles
Pathogenesis: cardiac function is impaired -> myocardial fibers stretch thereby increasing the contractile force, stroke volume, & CO -> the increased contractile force has a limit, after which increased stretch will result in a decrease in tension developing -> chronic dilation of a ventricle can occur through addition of sarcomeres & hence lengthening of myocytes
Etiology: acute overload
eccentric cardiac hypertrophy
concentric cardiac hypertrophy
eccentric cardiac hypertrophy
concentric cardiac hypertrophy
normal lung
could be normal, could be hemorrhage
precipitation of euthanasia solution
pleura thickened caudally, probably normal genetic variation in cattle
R lung congestion
cranio-ventral hyperemia
foam in trachea from pulmonary edema
pulmonary edema
foam down bifurcation - normal on post mortem
pleural hemorrhage (hard to see, will feel firmer)
pleural hemorrhage (hard to see, will feel firmer)
pulmonary embolism
pulmonary / pleural ossification
(no significance)
pulmonary anthracosis
(dust contained w/in macrophages)
could be melanoma, melanosis, v. dark hemorrhage
(palpate: melanoma would feel like a mass)
atelectasis
(pale, pink, poofy to deeper, darker red
pulmonary atelectasis
(darker parts)
pulmonary atelectasis
pulmonary atelectasis
(can see it is depressed where it is dark, sharp demarcation)
alveolar emphysema
bullous emphysema
bullous emphysema
combination of atelectasis & alveolar emphysema
(commonly seen in euth’d animals, bright red = emphysema, dark red = atelectasis)
