Name the condition

Question 1

Answer 1

myocardial hypertrophy
(greater contractility & ejection force)

Question 2

Answer 2

cardiac dilation
(increased stroke volume)

Question 3

Answer 3

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

Question 4

Answer 4

eccentric cardiac hypertrophy

Question 5

Answer 5

concentric cardiac hypertrophy

Question 6

Answer 6

eccentric cardiac hypertrophy

Question 7

Answer 7

concentric cardiac hypertrophy

Question 8

Answer 8

normal lung

Question 9

Answer 9

could be normal, could be hemorrhage

Question 10

Answer 10

precipitation of euthanasia solution

Question 11

Answer 11

pleura thickened caudally, probably normal genetic variation in cattle

Question 12

Answer 12

R lung congestion

Question 13

Answer 13

cranio-ventral hyperemia

Question 14

Answer 14

foam in trachea from pulmonary edema

Question 15

Answer 15

pulmonary edema

Question 16

Answer 16

foam down bifurcation - normal on post mortem

Question 17

Answer 17

pleural hemorrhage (hard to see, will feel firmer)

Question 18

Answer 18

pleural hemorrhage (hard to see, will feel firmer)

Question 19

Answer 19

pulmonary embolism

Question 20

Answer 20

pulmonary / pleural ossification
(no significance)

Question 21

Answer 21

pulmonary anthracosis
(dust contained w/in macrophages)

Question 22

Answer 22

could be melanoma, melanosis, v. dark hemorrhage
(palpate: melanoma would feel like a mass)

Question 23

Answer 23

atelectasis
(pale, pink, poofy to deeper, darker red

Question 24

Answer 24

pulmonary atelectasis
(darker parts)

Question 25

Answer 25

pulmonary atelectasis

Question 26

Answer 26

pulmonary atelectasis (can see it is depressed where it is dark, sharp demarcation)

Question 27

Answer 27

alveolar emphysema

Question 28

Answer 28

bullous emphysema

Question 29

Answer 29

bullous emphysema

Question 30

Answer 30

combination of atelectasis & alveolar emphysema (commonly seen in euth'd animals, bright red = emphysema, dark red = atelectasis)
