The correct Answer is:
To answer the question regarding which hormone(s) are referred to as emergency hormones or "fight or flight" hormones, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Concept of "Fight or Flight" Response**: - The "fight or flight" response is a physiological reaction that occurs in response to a perceived harmful event, attack, or threat to survival. This response is primarily controlled by the autonomic nervous system and involves the release of certain hormones. 2. **Identify Key Hormones Involved**: - The main hormones associated with the "fight or flight" response are adrenaline (also known as epinephrine) and noradrenaline (norepinephrine). These hormones are produced by the adrenal glands. 3. **Function of Adrenaline and Noradrenaline**: - Adrenaline increases heart rate, dilates air passages, and increases blood flow to muscles, preparing the body for rapid action. - Noradrenaline works to increase blood pressure and blood sugar levels, further supporting the body's ability to respond to stress. 4. **Conclusion**: - Therefore, the hormones that are called emergency hormones or "fight or flight" hormones are **adrenaline and noradrenaline**. ### Final Answer: Adrenaline and noradrenaline are the hormones referred to as emergency hormones or "fight or flight" hormones. ---
