Question 1 Report

Which of the following glands secretes a substance into the blood stream of a frightened person?
Answer Details
The gland that secretes a substance into the bloodstream of a frightened person is the adrenal gland. The adrenal gland produces adrenaline, a hormone that prepares the body for a "fight or flight" response in stressful situations. When a person is frightened, the adrenal gland releases adrenaline into the bloodstream, causing an increase in heart rate, blood pressure, and breathing rate. This response is designed to help the person respond quickly to a potential threat.
