Define stress, and describe factors that elicit a stress response
What will be an ideal response?
Stress is the generalized, nonspecific response of the body to any factor that overwhelms, or threatens to overwhelm, the body's compensatory abilities to maintain homeostasis. Contrary to popular usage, the agent inducing the response is correctly called a stressor, whereas stress refers to the state induced by the stressor. The following types of noxious stimuli illustrate the range of factors that can induce a stress response: physical (trauma, surgery, intense heat or cold); chemical (reduced O2 supply, acid–base imbalance); physiologic (heavy exercise, hemorrhagic shock, pain); infectious (bacterial invasion); psychological or emotional (anxiety, fear, sorrow); and social (personal conflicts, change in lifestyle).
