What happens when there is a sustained physiological activation in response to stress? the elasticity of the arteries increases. the rate at which fatty buildup takes place decreases. heart rate and blood pressure remain elevated. heart rate and blood pressure normalize?

heart rate and blood pressure remain elevated.

Explanation:

Emotion is a response of the body that involves physical, physiological and cognitive changes in the face of a certain stimulus. There is activation of the hypothalamus, sympathetic nervous system and increased circulating catecholamines (such as adrenaline, among others). These changes can eventually be harmful to the body, especially the heart. Stress is not an exception to this case. An organism under stress creates a series of physiological changes, including increased heart rate and blood pressure.
