in healthy individuals, urinary Na excretion decreases when there is an excess of sodium in the body and increases when there is a sodium deficit.?? T/F
when total-body sodium decreases for any reason, Na excretion decreases below normal levels
Why????
Why????
For the long - term regulation of Na excretion , the control of Na reabsorption is more important than the control of GFR?? T/F
Angiotensin II exerts many effects , but the most important are , the stimulation of the secretion of aldosterone and the constriction of arterioles .

لان جاي يكول في الأفراد الأصحاء ، ينخفض إفراز الصوديوم في البول عندما يكون هناك فائض من الصوديوم في الجسم ويزيد عندما يكون هناك نقص في الصوديوم وهو العكس
