Question

A young woman who lives alone comes home at night to find a man in her apartment. What body responses would be expected for the young woman?

A) Increased blood pressure (BP), increased heart rate, and pupil dilation
B) Decrease sweating, decreased BP, and increased heart rate
C) Pupil constriction, increased respiratory rate, and decreased heart rate
D) Increased sweating, decreased respiratory rate, and increased BP

Answer 1

In the given scenario, the young woman would experience a fight or flight response characterized by increased heart rate, increased blood pressure, pupil dilation, increased sweating, and an increased respiratory rate, corresponding to option A.

Step-by-step explanation:

When a young woman finds a man in her apartment unexpectedly, her body is likely to initiate a fight or flight response, triggered by the autonomic nervous system. This response includes several physiological changes:

• Increased heart rate to pump blood more efficiently to muscles and organs.
• Increased blood pressure (BP) due to vasoconstriction, which prepares the muscles for rapid action.
• Pupil dilation to enhance vision and identify threats quickly.
• Increase in sweating to help cool the body during rapid action.
• Increased respiratory rate, as the bronchi of the lungs dilate to allow for more air exchange.

Given these responses, the correct answer would be option A) Increased BP, increased heart rate, and pupil dilation.
