The Kidneys and Arterial Pressure

The two processes that occur in the renal-body fluid system for arterial pressure control are pressure diuresis (renal output of water if arterial pressure is high) and pressure natriuresis (renal output of salt if arterial pressure is high).

The kidneys play a role in long term control of arterial pressure by maintaining the balance of fluid intake and output. They regulate renal output of water (pressure diuresis) and salt (pressure natriuresis) based on arterial pressure levels.

When blood volume increases and vascular capacitance is not altered, arterial pressure will increase. This rising pressure will cause the kidneys to excrete the excess volume and restore pressure to normal.
