Final answer:
The body's reaction to a challenge or demand is called the stress response. It involves the release of stress hormones and physiological changes to prepare the body for a fight-or-flight response.
Step-by-step explanation:
The body's reaction to a challenge or demand is called the stress response. When faced with a stressor, such as an upcoming exam or a physical threat, the body activates its stress response system. This system involves the release of stress hormones, such as cortisol and adrenaline, which prepare the body for a fight-or-flight response.
For example, if a student is faced with a challenging test, their body may respond by increasing heart rate, breathing rate, and blood pressure. This physiological response helps the body to focus, stay alert, and respond effectively to the demand.
It is important to note that while the stress response can be beneficial in certain situations, chronic or excessive stress can have negative effects on both physical and mental health.
