e) more than one of the answers is correct.
10) define anemia, and explain how it is the same or different from hypoxemia. give
examples of three different types of anemia and a brief synopsis of each kind. is sickle
cell disease a true anemia? explain your answer. when sickle cell disease is fatal, what
is the cause of death?
11) which of the following will increase flow in a vessel the most?
a) decrease length by 1 unit
b) increase radius by 1 unit

a) glucose and galactose absorption uses an apical na+-glucose sglt symporter.
b) fructose moves across the apical membrane by active transport.
c) glucose and galactose use different transporters in absorption.
d) a basolateral glut5 transporter moves glucose out of the intestinal epithelial cell.
e) none of the statements are true.
16) match the glial cell to the nervous system division in which it is found.
a. central nervous system
b. peripheral nervous system
ependymal cells
17) digestive reflexes originating in the cns are called ________.
18) if sensitization is the opposite of habituation, and sensitization is adaptive, would
habituation be considered maladaptive? why or why not?
19) list and describe the lung volumes.
20) the inability for a male to obtain or sustain an erection is called ________.
21) what seems to be the most likely hormone that we could use as a male contraceptive
pill? explain.
22) explain how an animal with a paralyzing spinal injury can be induced to walk,
though it can’t walk on its own. diagram and label the structures involved. (hint: keep it
simple; for example, you could draw a rectangle and label it “right leg muscle” and
another for the left, and don’t worry about drawing all neurons involved, just enough to
show you understand the basics. you may wish to start with a simple sketch of a muscle
reflex then add on to it as necessary.)
23) draw a graph showing what would happen to resting membrane potential over time,
if the sodium/potassium pump were not functioning. how would this affect a neuron’s
ability to produce action potentials? what does this imply about the quantity of ions that
normally cross the membrane during the course of an action potential?
24) a diagnosis of thyroid cancer may be treated with removal of the thyroid gland.
which hormone or hormones may now be deficient? considering each hormone
individually, which ones should be restored and why? explain any age-related
considerations. which nonthyroid hormone may be affected by careless thyroidectomy?
explain your answer, indicating whether or not it is critical to maintain this hormone.
