Acute kidney injury (AKI) in humans is a common clinical problem caused by damage to the epithelial cells that comprise kidney nephrons, and AKI is associated with high mortality rates of 50-70%1. Following epithelial cell destruction, nephrons have a limited ability to regenerate, though the mechanisms and limitations that guide this phenomenon remain poorly understood. In this video article, we describe our technique for targeted laser ablation of kidney nephron cells in the zebrafish...

2025
The kidneys are vital organs responsible for regulating blood filtration, waste excretion, and fluid balance, all of which are crucial for maintaining homeostasis. Renal physiology examines renal blood flow, glomerular filtration, and urine formation, ensuring the body’s internal environment remains stable.Renal Blood FlowThe kidneys receive about 20-25% of the cardiac output, typically around 1200 mL of blood per minute in an average adult. Blood flows into the kidneys through the renal...

Early stage hemodynamic dysfunction is critical to the development of kidney disease. Yet, detection methodologies are limited. Recent advances in sonography provide a noninvasive, accurate option for early detection of kidney injury. This study outlines a step-by-step, sonographic methodology for detecting kidney dysfunction using a drug-induced nephrotoxicity rat model.

FAQs
The ultrafiltrate does not remain unchanged after glomerular filtration. As it passes through the renal tubule, selective reabsorption removes substances that the body retains, while secretion adds selected substances to the tubular fluid. These opposing adjustments progressively determine the composition of urine and allow the kidneys to regulate fluid, electrolyte, and waste balance.
Antidiuretic hormone provides hormonal control over water conservation in the kidney. Its action changes how the renal system handles water, helping regulate the amount retained rather than lost in urine. Studying this signal shows how renal physiology integrates nephron activity with whole-body fluid balance and explains why hormonal regulation is important for maintaining internal conditions.
Filtration begins urine formation, but it does not by itself establish the final urinary composition. Reabsorption selectively returns needed material from the tubular fluid, whereas secretion moves additional substances into it. Together, these processes refine the initial filtrate, support electrolyte and fluid regulation, and ensure that metabolic waste can be removed without treating all filtered material identically.
Nephron processes have consequences beyond waste removal because they influence the composition and volume of body fluids. The overview links renal function with blood pressure regulation and acid-base balance, showing that changes in filtration or tubular handling can affect broader internal conditions. This makes the nephron a useful structural and functional framework for studying kidney-related disturbances.
A clear study sequence is to begin with nephron structure, follow glomerular filtration, and then trace selective reabsorption and secretion along the renal tubule. Next, examine hormonal control of water conservation and connect these events with urine formation. This progression links microscopic kidney organization to fluid balance, waste removal, and broader physiological regulation.
Renal physiology supports analysis of impaired filtration, electrolyte disturbances, and laboratory measurements related to kidney function. It also provides context for interpreting changes in urine formation, fluid regulation, blood pressure, acid-base balance, and endocrine function. In biology and medicine, these connections help relate measurable findings to the underlying processes occurring within the nephron.
