Question

Ashaley has returned home from a root canal procedure at her dentist's office. The stressful situation she had dreaded is over. Erin's _____ nervous system is now taking over as her body returns to a normal, relaxed state.

A.sympathetic
B.somatic
C.lymphatic
D.parasympathetic

Answer 1

The D. Parasympathetic nervous system is taking over.

Step-by-step explanation:

The autonomous nervous system has 2 divisions, the sympathetic and parasympathetic nervous systems.

• The parasympathetic system is in charge of saving energy, of relaxing the body after a moment of stress. It relaxes the heartbeats and the lungs after an amount of energy has been used.
• Unlike the parasympathetic system, the sympathetic system is in charge of energetic reactions in order to prepare the body for a stressful situation.

In this case, the parasympathetic system is taking over as the girl's body returns to a normal, relaxed state since it is regulating the body after the moment of stress and drain of energy generated by the dread to go to the dentist.
