مقارنة بين تأثيرات الجهازين الودي ونظير الودي

but Question plz :
could u plz explain the effects of both systems on kidneys ,i mean which function of it is affected....

Good question ....here is what I found:

First of all, kidneys receive innervation only from the sympathetic system.
((((Organs receiving only sympathetic innervation: Although most tissues receive dual innervation, some effector organs, such as the adrenal medulla, kidney, pilomotor muscles, and sweat glands, receive innervation only from the sympathetic system. The control of blood pressure is also mainly a sympathetic activity with essentially no participation by the parasympathetic system))))……Lippincott pharmacology

Secondly, Here are the effects of Sympathetic Nervous System on kidneys:
((((Stimulation of the sympathetic neurons to the kidney generally causes vasoconstriction:
decreases GFR (Glomerular Filtration Rate)
Increases FF (Filtration Fraction)
Increases factors promoting reabsorption in the peritubular capillaries, i.e., lower capillary hydrostatic pressure and an increase in plasma oncotic pressure (proteins are more concentrated) ))))…….Kaplan physiology

hope it helps
