In response to a lowering of the plasma sodium concentration, or to a fall in the arterial blood pressure, the juxtaglomerular cells release renin into the blood. This is tightly regulated to ensure that there is no excessive build-up homeostasis nedir carbonic acid or bicarbonate. However, it is not certain whether a “salt hunger” can be initiated by hyponatremia, or by what mechanism homeostasis nedir might come about.
