Answer:
adrenaline, stress
Explanation:
In every harmful situation, the body has a natural tendency to enter into the fight-or-flight response.
Fight-or-flight response- This is a physiological response of a person's body in the event of danger. This term was coined by Walter Bradford Canon, an American physiologist and professor. According to him, when a person faces a harmful event, it triggers the <u>sympathetic nervous system</u> to either <em>"fight"</em> the situation or <em>"flee" </em>from it. Once this happens, the person's adrenal gland becomes activated.
Adrenal gland- This is the gland responsible for the release of hormones such as adrenaline, cortisol, aldosterone, etc.
The activation of the adrenal gland, prompts it to release the adrenaline, which is also known as the <em>fight-or-flight hormone. </em>The body will now prepare to either fight or flee. <em>This explains the first answer above regarding Amir's situation.</em>
Once the body responds, it will now exhibit short-term effect of stress. This includes: <em>increase heart rate, flushing, shaking, constriction of the blood vessels in the body, relaxation of bladder, dilation of the pupils and many more! </em><em>This explains the second answer above.</em>
