Question

Quizplus · Accepted Answer

The regulation of sodium is linked to blood pressure. Sodium is an electrolyte that plays a key role in controlling the volume of extracellular fluid in the body, which in turn affects blood pressure. When sodium levels are high, the body retains water to maintain a balance of electrolytes and blood volume, which can lead to increased blood pressure. Conversely, low sodium levels can lead to decreased blood pressure.

Answer: D
 The regulation of sodium involves aldosterone, a hormone that increases sodium excretion in the kidneys. Aldosterone is produced by the adrenal gland and acts on the kidneys to increase the reabsorption of sodium and the secretion of potassium, which helps to maintain electrolyte balance in the body. When sodium levels are low, aldosterone is released to signal the kidneys to retain more sodium and excrete more potassium, which helps to raise blood pressure and maintain proper electrolyte balance.
