What are two examples of cardiovascular reactivity triggered by provocation?

In the context of cardiovascular reactivity, particularly in response to psychological or physiological stressors, the body often exhibits specific changes in heart rate and blood pressure. The correct choice reflects the common physiological response to provocation, where the body prepares itself to handle potential challenges or threats.

Increased heart rate and elevated blood pressure are key indicators of the body's fight-or-flight response, which is activated during stressful situations. When provoked, the autonomic nervous system triggers adrenaline release, which leads to heart rate acceleration and vasoconstriction, causing blood pressure to rise. This reaction ensures that more oxygen and nutrients are delivered to vital organs and muscles, preparing the individual for action.

The other options describe responses that are typically associated with relaxation or non-stress states. For instance, a decreased heart rate and lower blood pressure suggest a calming effect rather than a reactive one. Similarly, normal blood sugar levels or elevated insulin might not be directly linked to cardiovascular reactivity in the context of stress. Instead, they could indicate a more stable state of metabolic function rather than a provocation response.
