Why is it important for the sympathetic nervous system to be able to override the kidney's autoregulatory systems?

If blood pressure drops too low due to excessive fluid loss, then the sympathetic nervous system will override renal autoregulation. Sympathetic nerves innervate the afferent arteriole, causing smooth muscle contraction, decreased GFR and decreased fluid loss via urine.
Another effect of the sympathetic nervous system is to stimulate renin secretion by the juxtaglomerular cells, activating the renin-angiotensin-aldosterone system (RAAS). The RAAS increases extracellular fluid volume by increasing sodium reabsorption (see later web page on sodium).

How do the kidneys react to sympathetic nervous system stimulation?
Sympathetic stimulation results in renin secretion by the kidneys and causes a relaxation of the bladder. Accompanied by a constriction of the bladder sphincter, sympathetic stimulation tends to decrease urination and promote fluid retention.
What known functions result from sympathetic innervation into kidneys?
regulation of blood flow
What sympathetic ganglion distributes postganglionic neuronal processes to the kidneys?
aorticorenal ganglion
What is the sympathetic ganglion that distributes postganglionic neuron processes to the kidneys and gonads?
The sympathetic ganglion that distributes postganglionic neuron processes to the kidneys and gonads is the prevertebral ganglion called the superior mesenteric ganglion. It is located in the abdominal cavity, anterior to the aorta and just below the origin of the superior mesenteric artery.
What parts of the body receive only sympathetic fibers?
adrenal medulla, sweat glands, arrector pili muscles of the skin, kidneys, most blood vessels

The fatty tissue surrounding the kidneys is important because?

Why is water important to the kidneys?
Kidneys must excrete water in the urine so as to maintain homoeostasis in the body. The kidneys will excrete concentrated urine.
