Answer 1

B. sympathetic nervous system

Step-by-step explanation:

This is a type of the Autonomic nervous system. The sympathetic nervous system is responsible for the body's fast involuntary response to dangerous or stressful situations. This response is usually exhibited by a flash flood of hormones being released into the bloodstream to boosts the body's alertness and heart rate thereby sending extra blood to the muscles.

These signs such as difficulty in concentrating,increase in heartbeat, stomach seeming tied in a knot, heavy breathing , dry mouth tells when someone is in a very tensed situation.

Answer 2

Answer: B) sympathetic nervous system

Explanation: The sympathetic nervous system is a section of the automatic nervous system in the body that reacts to stressful or dangerous situations by stimulating the fight-flight-or-freeze response. This causes the body's alertness to increase as well as increase in the rate of heartbeat.

Some of the visible symptoms includes Hypertension, Agitation. Muscle rigidity, Heavy breathing etc.

The fact that the individual didn't study for the exam he or she is writing puts the individual in a stressful position, that is why his or her sympathetic nervous system kicked in to stimulate the body's fight-flight-or-freeze response, causing the individual's rate of heart beat to increase as well as having dry mouth.
