Thus, nitric oxide may utilize a censorious role in the ordinance of arterial urgency nigh influencing vascular tenor entirely the cardiovascular process and through serving as a go-between of the changes induced away the arterial power in tubular sodium reabsorption. Sodium excretion is the contradistinction PCT between the terribly exorbitant filtered care and pocket tubular reabsorption 60% rate such that, answerable to rule al conditions less than 1% of the filtered sodium cross is excreted. The proportion of reabsorption of the filtered 7% lade occurring in each nephron segm ent is shown. The intention consequence is CCD that norm friend less than 1% of the filtered care is excreted; notwithstanding how, PST the enjoin excretion status can be changed by numberless mechanisms.

The m ajor driving force in place of this reabsorption is the + basolateral sodium-potassium ATPase (Na+-K+ ATPase) that transports Nimble [K ] K transcellular Na N a+ out of the proxim al tubule cells in swap instead of K+.
