The sympathetic nervous system is responsible for up- and down-regulating many homeostatic mechanisms in living organisms. Fibers from the SYNS innervate tissues in almost every organ system, providing at least some regulation of functions as diverse as pupil diameter, gut motility, and urinary system output and function. It is perhaps best known for mediating the neuronal and hormonal stress response commonly known as the fight-or-flight response. This response is als… WebThe kidneys’ main job is to filter the blood to remove the waste - so it shouldn’t be surprising that they receive about a quarter of the blood that the heart pumps with each beat. On average, the heart pumps out almost 5 liters of blood every minute, so one-quarter of that - or 1.25 liters - flows into the renal artery every minute.
