Question

a medical equipment company is thinking of expanding by developing a higher tech version of the presently used lie-detection machines that measure perspiration, cardiovascular, and respiration changes. on which of the following systems should its research focus?
the biopharmacological system
the adrenal system
the sympathetic nervous system
the central nervous system

Explanation:

Lie detection machines measure perspiration, cardiovascular, and respiration changes. These physiological responses are regulated by the sympathetic nervous system, which activates the body's "fight-or-flight" response, triggering increased sweating, heart rate, and respiratory rate. The other systems do not directly control all these specific measured functions.

Answer:

the sympathetic nervous system
