Investigate the role of the kidneys in maintaining fluid and electrolyte balance

Investigate the role of the kidneys in maintaining fluid and electrolyte balance, acid-base homeostasis, and waste excretion. Discuss the anatomy and function of the nephron, including glomerular filtration, tubular reabsorption, and secretion processes. Analyze the mechanisms of renal regulation of water balance, electrolyte concentrations, and blood pH, including the role of hormones such as aldosterone, antidiuretic hormone (ADH), and atrial natriuretic peptide (ANP). Evaluate the pathophysiology of renal disorders such as kidney stones, renal failure, and electrolyte imbalances, and the implications for fluid and electrolyte management and renal replacement therapy.
