Stress drawing 插畫檔

The effects of stress on the body - the resistance phase. During stress, whether physical or psychological, the body reacts in three stages: the alarm phase (first reactions to the aggression with acceleration of the heart rate and breathing), the resistance phase (adaptation of the body when the stress persists) and the exhaustion phase (illness and death). Stress (red) activates the hypothalamus, which stimulates the pituitary gland via corticostimulant hormone (CRH). In response, the adenohypophysis produces ACTH (AdrenoCorticoTropin Hormone or corticotropic hormone, green)
