Question

Which of the following regulates the reabsorption of salts from glomerular filtrate?

• A. Oxytocin
• B. Vassopressin
• C. Glucocorticoides
• D. Mineralocorticoides

Answer 1

The correct option is D Mineralocorticoides

The principal mineralocorticoid is aldosterone. Aldosterone helps to regulate fluid balance by regulating salt balance. In response to aldosterone, the kidneys reabsorb more sodium and excrete more potassium. As a result of increased sodium, extracellular fluid volume increases, which results in greater blood volume and elevated blood pressure. When the adrenal glands do not produce enough aldosterone, large amounts of sodium are excreted in the urine. Water leaves the body with the sodium (because of osmotic pressure), and the blood volume may be so markedly reduced that the patient dies of low blood pressure.

So, the correct answer is 'Mineralocorticoides'
