EEOB 2520 EXAM 1 WITH COMPLETE
SOLUTIONS
Capillary walls Correct Ans-Barrier between plasma and interstitial fluid
Cell membrane Correct Ans-Barrier between interstitial fluid and intracellular fluid
D Correct Ans-Which is a correct statement about a homeostatic control system?
A. During feedforward, equilibrium is not needed to return the body to steady state.
B. Negative feedback always moves the body back toward its set point.
C. A feedback mechanism will cost the body more energy that a feed forward mechanism.
D. All three of these statements are correct about a homeostatic control system.
A Correct Ans-Which is a correct statement about functional units?
A. Redundancy does not allow organs to make new functional units, even if some are lost.
B. Organs can only have more than one functional unit.
C. Both statements are correct about functional units.
D. Neither statement is correct about functional units.
A Correct Ans-Which is a correct statement about nonfibrous proteins found in the
extracellular matrix?
A. They provide the structure between the cells.
B. They are the only components found within the matrix.
C. An example of one would be the rope-like collagen.
D. All three of these statements are correct about nonfibrous proteins found in the extracellular
matrix.
, D Correct Ans-Capillary walls separate the ___ fluid compartments while the cell membrane
separates the ___ fluid compartments.
A. Middle sized and interstitial - smallest and largest
B. Intracellular and plasma-interstitial and largest
C. Largest and plasma-interstitial and intracellular
D. Smallest and interstitial - middle sized and largest
A Correct Ans-In physiology, _____ is a change that occurs to a(n) _____.
A. Acclimatization - individual
B. Acclimatization - species
C. Adaptation - individual
D. Adaptation - free radical
B Correct Ans-Otago, the food-loving dog, is often hungry. When it is time to eat, her
stomach sends signals through her ___ to her brain which then sends signals through her ___ so
she moves to her food bowl and eats.
A. Reflex arc - paracrine
B. Reflex arc - efferent
C. Efferent - afferent
D. Paracrine - afferent
B Correct Ans-Alaskan resident Carmen (formerly from Ohio) visited her friend Brutus last
winter on one of the coldest, central-Ohio days (it was about 10o F). Brutus could not
understand why she did think it was cold but instead thought it was rather comfortable (it was
often about -20o F in Alaska). In a conversation with Brutus over a box of buckeyes, you
correctly inform him that
A. Carmen has the same set point than him.
B. Carmen has not experienced a developmental acclimatization relative to temperature.
