Verified step by step guidance1
Understand the context of the 'fight or flight' response, which is the body's acute stress response mechanism.
Identify the role of hormones in the 'fight or flight' response, focusing on how they prepare the body to either confront or flee from a threat.
Recognize that adrenaline, also known as epinephrine, is the primary hormone responsible for the 'fight or flight' response.
Learn that adrenaline is released from the adrenal glands and acts to increase heart rate, blood pressure, and energy availability by signaling the liver to release glucose into the bloodstream.
Differentiate between the roles of other hormones listed: cortisol (a stress hormone that also increases glucose availability but over a longer period), glucagon (which raises blood glucose levels but is not primarily involved in acute stress), and insulin (which lowers blood glucose levels).
