The <u>adrenal gland</u> releases a torrent of hormones, such as epinephrine and norepinephrine as the fight or flight response when a person is stressed or scared.
<h3>What are adrenal glands?</h3>
The adrenal glands are two small organs responsible for secreting hormones such as cortisol, adrenaline or noradrenaline into the bloodstream.
<h3>Characteristics of adrenal glands</h3>
- They are responsible for producing hormones that help regulate metabolism, the immune system, blood pressure, the response to stress and other essential functions.
- The main hormones secreted by the adrenal medulla include epinephrine (adrenaline) and norepinephrine (noradrenaline), which initiate the fight or flight response.
Therefore, we can conclude that the adrenal glands release certain hormones in response to stress, some of which are vital for survival.
