Question

parasympathetic division
the parasympathetic division is most active when the body is at rest and not threatened in any way. this division, sometimes called the
est - and - digest\ system, is chiefly concerned with promoting normal digestion, with ( 1 ) of feces and urine, and with conserving body energy, particularly by decreasing demands on the cardiovascular system. its activity is best illustrated by a person who relaxes after a meal and reads the newspaper. blood pressure and heart and respiratory rates are being regulated at low - normal levels, the ( 2 ) tract is actively digesting food, and the skin is warm (indicating that there is no need to divert blood to skeletal muscles or vital organs). the eye pupils are constricted to protect the retinas from excessive damaging light, and the lenses of the eyes are \set\ for close vision. we might also consider the ( 3 ) division as the \housekeeping\ system of the body.
an easy way to remember the most important roles of the two ans divisions is to think of the parasympathetic division as the d (digestion, defecation, and diuresis urination) division and the sympathetic division as the e (exercise, excitement, emergency, and embarrassment) division. remember, however, that although it is easiest to think of the ( 4 ) and parasympathetic divisions as working in an all - or - none fashion, this is rarely the case. a dynamic balance exists between the two divisions, and both are continuously making fine adjustments. also, although we have described the parasympathetic division as the \at - rest\ system, most blood vessels are ( 5 ) only by the sympathetic fibers regardless of whether the body is \on alert\ or relaxing.

Explanation:

• For blank 1: "elimination" fits as it relates to feces and urine expulsion.
• For blank 2: "digestive" tract is involved in food digestion.
• For blank 3: The text refers to the parasympathetic division as the "housekeeping" system.
• For blank 4: Sympathetic and parasympathetic divisions are compared.
• For blank 5: "controlled" is appropriate as it describes the action on blood vessels by sympathetic fibers.
