Question

Which physiological response is described as producing sleep, dilating blood vessels, constricting bronchial passageways, protecting against seizures, and slowing down the body's reaction to stress while lowering blood pressure, heart rate, and temperature?

A) Parasympathetic nervous system
B) Sympathetic nervous system
C) Endocrine system
D) Immune system

Answer 1

The parasympathetic nervous system is responsible for producing sleep, dilating blood vessels, constricting bronchial passageways, protecting against seizures, and lowering blood pressure, heart rate, and temperature.

Step-by-step explanation:

The physiological response that is described as producing sleep, dilating blood vessels, constricting bronchial passageways, protecting against seizures, and slowing down the body's reaction to stress while lowering blood pressure, heart rate, and temperature is the parasympathetic nervous system.

The parasympathetic division of the autonomic nervous system is responsible for returning the body to normal after the fight-or-flight response has occurred. It promotes relaxation, rest, and digestion.

For example, when the sympathetic division is activated in response to a stressful situation, the parasympathetic division works to reset the organ functions and bring the body back to a relaxed state.
