summary of our body’s reaction to stress

I would like to know if there is something else I could improve on my work. I was asked to make a small summary of our body’s reaction to stress—including changes to the nervous system, hormones, and heart. The attached file contain my summary.

 

Stress definition Stress is a reaction which occurs when our body fail to manage or to respond to an emotional or physical events that happened[Int1]. Summary of our body’s reaction to stress—including changes to the nervous system, hormones and heart. Our body is created in a way that it can fight, adapt or react to an unusual events such as stress. Speaking of stress, our body has a way of adaptation which is in form of three stages. Those stages are: general alarm reaction, resistance, and exhaustion.[Int1] Stage one In the stage one called general alarm, our body try to release stress hormones including cortisol. When our body face a stressor event, a response is sent to the nervous system. Immediately, the hypothalamus starts to secrete releasing hormones. Those releasing hormones are the ones to direct the pituitary gland to release the hormone ACTH. That ACTH directs the adrenal gland to secrete hormones such as epinephrine, norepinephrine and adrenaline and cortisol. Cortisol is a stress hormone that releases sugars into the blood thus preparing the body to respond to the threat. In case the stress experience is prolonged, the adrenal continue to release cortisol. Adrenaline and cortisol hormones make the heart beat feaster than usual, respiration rate to increase, blood vessels in the arms and legs to dilate, digestive process to change and glucose levels (sugar energy) in the bloodstream to increase to deal with the emergency.[Int1] Stage two In the second stage called resistance, our body try to adapt so as to return to its normal functionality. Here, it increases the glucose level so as to sustain energy, and blood pressure increases.[Int1]

Stage three In the third stage which also the last one, our body had run out of its reserves energy. The glucose level and blood pressure decreases. Our body organs became weak and this is very dangerous because it leads to stress intolerance, illness and sometimes death may occur.[Int1]
