What is the role of aldosterone in our body?
Options
- AMaintains the electrolytes, body fluid volume, osmotic pressure and blood pressure
- BStimulates the RBC production
- CStimulates gluconeogenesis and lipolysis
- DPromotes production of antibodies
Correct answer
A. Maintains the electrolytes, body fluid volume, osmotic pressure and blood pressure
Step-by-step solution
Glucocorticoids stimulate gluconeogenesis, lipolysis and proteolysis; and inhibit cellular uptake and utilisation of amino acids. Cortisol is also involved in maintaining the cardio-vascular system as well as the kidney functions. Glucocorticoids, particularly cortisol, produces anti-inflammatory reactions and suppresses the immune response. Cortisol stimulates the RBC production. Aldosterone acts mainly at the renal tubules and stimulates the reabsorption of Na+ and water and excretion of K+ and phosphate ions. Th
