Explanation / Answer

The body is exposed to a stressor --> the hypothalamus releases corticotropin releasing hormone --> CRH stimulates the release of the hormone adrenocorticotropic hormone from the anterior pituitary gland --> the hormone adrenocorticotropic hormone stimulates the release of the hormone cortisol from the adrenal cortex --> the level of the hormone cortisol in the blood rises --> the hormone cortisol causes the restoration of homeostasis --> the body adapts to the stressor --> the level of the hormone cortisol decreases in the blood.

The decrese in the level of cortisol in blood is by negative feedback regulation. Once the cortisol levels rise, the production of corticotropin releasing hormone in the hypothalamus and the release of adrenocorticotropic hormone from the pituitary gland are blocked thus leading to the reduction in the levels of cortisol in blood.
