Question

Quizplus · Accepted Answer

Excretion of excess sodium by the kidneys is the primary way in which the body regulates sodium levels. The kidneys filter out sodium and excess sodium is excreted in the urine. Other factors such as hormones and the renin-angiotensin-aldosterone system also play a role in regulating sodium levels. Sodium levels are primarily regulated through excretion by the kidneys. When the body senses it has too much sodium, the kidneys will excrete more through urine. Conversely, when the body senses it has too little sodium, the kidneys will retain more. Intestinal absorption and fecal excretion can also play a role, but to a lesser extent. The liver does not play a significant role in sodium regulation.
