The process of excreting large amounts of sodium through urine.
Natriuresis can help regulate blood pressure by reducing sodium levels in the body.
Natriuresis is formed from "natrium" (from Latin, meaning sodium) and "uresis" (from Greek "ourēsis", meaning urination). The term describes the process of excreting sodium in the urine.
Think of 'sodium' ('natrium') being 'excreted' ('uresis') in urine — that's what natriuresis means.
