activities are
A) epithelial cells.
B) muscle cells.
C) connective tissue cells.
D) neurons.
E) Two of the choices are correct.

C) Homeostasis
D) Positive feedback
E) Acclimatization
8) Which best describes the extracellular matrix?
A) It is found just inside the cell membrane in all tissues, it sends branching collagen
fibers between cells to connect them, and it transmits chemical information from the
interior of one cell to the interior of adjacent cells.
B) It is a tissue having more than the four general cell types, it transports proteins and
polysaccharides between body compartments, and it is the route by which chemical
signals like hormones reach all parts of the body.
C) It covers the body's surface, it contains connective and muscle tissue, and it helps
generate movement.
D) It surrounds cells; it contains proteins, polysaccharides, and minerals; it provides a
scaffold for cell attachment; and it transmits chemical messengers to cells.

,9) If a person begins to sweat upon entering a hot room but continued sweating is able to keep
the body temperature stable, which of these best describes their condition?
A) They are in an equilibrium state.
B) They are not using energy to maintain a constant temperature.
C) They are in a steady state.

10) Which concept is the defining feature of the discipline of physiology?
A) Descent with modification
B) Homeostasis
C) Evolution
D) Equilibrium
E) Differentiation
11) Describing a physiological variable as "homeostatic" means that it
A) has varied from the normal value, and will remain constant at the new value.
B) never varies from an exact set point value.
C) is in an equilibrium state that requires no energy input to stay at the normal value.
D) is in a state of dynamic constancy that is regulated to remain near a stable set point
value.
E) has no normal range, but will instead change to match the outside environmental
conditions.
12) Which of the following situations best represents a homeostatic mechanism?
A) A person who becomes nervous begins to sweat profusely.
B) After going outside on a hot day, the core body temperature increases.
C) Increasing the size of fast-food restaurant portions causes body weight to increase.
D) After eating a large batch of salty popcorn, levels of salt in the urine increase to rid it
from the body.
E) As age increases, the amount of calcium in bones decreases.

flows through them following a stimulus?

B) Effector, efferent pathway, integrating center, afferent pathway, receptor
C) Integrating center, receptor, afferent pathway, efferent pathway, effector
D) Receptor, efferent pathway, integrating center, afferent pathway, effector
E) Receptor, afferent pathway, integrating center, efferent pathway, effector
15) Feedforward regulatory processes
A) work in anticipation of changes in regulated variables.
B) are identical to positive feedback processes.
C) lead to instability of the regulated variable.
D) maximize fluctuations in the regulated variable.
E) tend to force physiological variables away from their set point.
16) Which situation is an example of feedforward regulation?
A) Blood glucose returns toward normal an hour after a meal.
B) The smell of rotten food on a plate triggers the vomit reflex.
C) A drop in core body temperature triggers shivering.
D) An increase in core body temperature stimulates sweating.
E) Food in the stomach triggers the production of stomach acid.
