Aldosterone from the adrenal cortex causes sodium ions to be

retained to maintain effective  vascular circulating volume and on the other hand, the elimination of potassium and magnesium.

Explanation:

The adrenal glands are bilateral structures divided into two distinct zones: the cortex and the marrow. The adrenal cortex is subdivided into 3 zones, each with specific anatomical characteristics. The glomerular zone, composed of cuboid and columnar cells, with a dense nucleus and scarce cytoplasm with few lipids, is arranged in coniferous clusters of compact nests, secretes a mineralocorticoid hormone known as aldosterone.

Aldosterone acts on the regulation of electrolyte homeostasis in extracellular fluid, mainly sodium (Na) and potassium (K). Exerts its effect on distal and distorted tubules and Nephron collecting duct. Aldosterone production is under the control of serum levels of renin, angiotensin, and K.
