Can you explain the regulation of adrenal cortex function by the way of the pituitary gland stimulation of the adrena?

Feedforward/feedback: Hi. Hypothalamus important, but to keep it simple, pituitary ACTH stimulates the adrenal cortex to make cortisol. Cortisol negatively feeds back to suppress pituitary ACTH. If cortisol falls or a big stress is encountered, ACTH goes up and stimulates more cortisol production. The pituitary "sees" the increase in cortisol, and cuts back on ACTH to keep cortisol in appropriate range. Diurnal pattern ...Read more

What are two ways the endocrine system directly impacts the functions of the cardiovascular system?

What are two ways the endocrine system directly impacts the functions of the cardiovascular system?

Many...: Via adrenaline it puts more stress on the heart, making it beat harder, stronger and faster. Nor-adrenaline causes the blood vessels to contract, raising the blood pressure. High Insulin levels, as in "pre-diabetes" cause the release of free fatty acids which damages the blood vessel walls, causing plaque formation. Cortisol and other hormones also have adverse effects. ...Read more
