This is the answer side of the first card in this set. Make sure
you select "definition" in the "start with" box. Otherwise you
will just see the answers first, which isn't super productive.
(I had to do this because quizlet only allows images on
the back of cards. Which is dumb. But we work with what
we've got).

that's just a personal preference.

The answer is D. The illustration shows marked hypertrophy
of the left ventricle. Hypertrophy of this extent, often seen
in hypertensive heart disease, is caused by increased
workload from increased ventricular pressure. This organ
enlargement is the result of an increase in size of the
individual muscle cells.
Ans: The illustration shows a section of the heart from a
45-year-old African-American man with long-standing
hypertension who died of a "stroke." Which of the
following adaptive changes is exemplified in the
illustration?
(A) Aplasia
(B) Atrophy
(C) Hyperplasia
(D) Hypertrophy
(E) Hypoplasia
The answer is A. The patient has renal agenesis, absence
of the kidney due to failure of organ development. The
congenital lack of one kidney differs from atrophy, in
which a decrease in the size of an organ results from a
decrease in the mass of preexisting cells. Unilateral renal

agenesis is usually a harmless malformation, and the
opposite kidney is often enlarged due to compensatory
hypertrophy. Bilateral renal agenesis is incompatible with
life and is of special interest since it can lead to the Potter
progression (see Chapter 17).
Ans: A 16-year-old girl undergoes radiologic imaging of
her abdomen and is found to have only one kidney. She
had been entirely unaware of this problem. Which of the
following terms is most descriptive of this finding?
(A) Agenesis
(B) Atrophy
(C) Hyperplasia
(D) Hypoplasia
(E) Metaplasia
The answer is E. The sequence of events in hypoxic cell
damage is as follows: Hypoxia results in failure of oxidative
phosphorylation, with resultant depletion of ATP and
increase in adenosine monophosphate and adenosine
diphosphate. Anaerobic glycolysis and glycogenolysis are
stimulated (notinhibited) through increased
phosphofructokinase and phosphorylase activities,

respectively. This results in an accumulation of cell lactate,
with a decrease in intracellular pH and depletion of
cellular glycogen stores. Decreased availability of ATP
also results in failure of the Na+K+-ATPase pump, which
then leads to increased cell Na+ and water and
decreased cell K+.
Ans: An impending myocardial infarction was successfully
averted by thrombolytic (clot-dissolving) therapy in a 55-
year-old man. Which of the following biochemical events
most likely occurred during the period of hypoxia?
(A) Decreased hydrogen ion concentration
(B) Increase in oxidative phosphorylation
(C) Loss of intracellular Na+ and water
(D) Stimulation of ATP synthesis
(E) Stimulation of anaerobic glycolysis and glycogenolysis
The answer is C. Pancreatic enzymatic fat necrosis
represents autodigestion by proteolytic and lipolytic
enzymes released from damaged parenchymal cells of
the pancreas. Fatty acids liberated by the digestion of fat
form calcium soaps, a process referred to as
