Hormones can react to increase blood pressure when it becomes low‚ the sympathetic division of the autonomic nervous system uses several ways to temporarily increase blood pressure when it has dropped for example during the fight or flight response. During the response‚ the sympathetic division is needed to stimulate the adrenal glands to release the hormones epinephrine and norepineprine which stimulate the heart to beat faster and for blood to flow more forcefully‚ this effect makes most of the
