Renal physiology is the study of how the kidneys function to maintain the body's balance of fluids, electrolytes, and waste products. The kidneys filter blood, removing toxins and excess substances, which are then excreted as urine. This process is crucial for regulating blood pressure, pH levels, and overall homeostasis.
The kidneys consist of tiny functional units called nephrons, which play a key role in filtration and reabsorption. Each nephron filters blood, reabsorbing essential nutrients and water while excreting waste. This intricate system ensures that the body retains what it needs while eliminating what it doesn't, keeping us healthy and balanced.
