Nephron necklace | sterling silver
The functional unit of the kidney — the microscopic tube that filters blood, recovers what the body needs, and discards the rest.
The Anatomy of the Nephron
Each nephron consists of a glomerulus (a tuft of capillaries enclosed in Bowman's capsule), a proximal convoluted tubule (reabsorbs 60–70% of filtered sodium, glucose, and amino acids), the loop of Henle (creates the medullary concentration gradient), the distal convoluted tubule (regulated reabsorption of calcium, sodium, and potassium), and the collecting duct (final water reabsorption regulated by ADH). Juxtamedullary nephrons have long loops of Henle that extend deep into the medulla, enabling maximum urine concentration. The juxtaglomerular apparatus — a specialised region where the distal tubule returns close to its parent glomerulus — senses tubular flow rate and secretes renin to regulate systemic blood pressure.
A Meaningful Gift for Science Lovers
A piece for nephrologists, physiologists, and medical students who have studied renal tubular function.
- For a nephrologist or renal physiologist who works at the level of the nephron
- For a researcher studying tubular transport, drug nephrotoxicity, or renal disease
- For a medical student who has worked through the physiology of renal handling
- For anyone who appreciates that the most complex organ functions reduce to elegant molecular transport

FAQ
Q: Who would appreciate this beyond nephrologists?
A: Medical students studying renal physiology, clinical pharmacologists interested in drug filtration and reabsorption, anyone whose work touches electrolyte balance, diabetes management, or dialysis. Also for people reflecting on filtration at any scale.
Q: Why can the kidney reabsorb so much glucose but still spill some in urine?
A: The proximal tubule has limited carrier-mediated reabsorption capacity (the Tm, or transport maximum). When blood glucose exceeds approximately 180 mg/dL, not all filtered glucose can be reclaimed, so it appears in urine. That's why glycosuria is a sign of hyperglycemia.
Q: What are the specifications?
A: 34 mm pendant in sterling silver (925, rhodium-plated) on a 45 cm chain. Nickel-free, high-polish finish. Free worldwide DHL shipping with 30-day return policy.
Q: What if I want a gold version?
A: Yes, the nephron is also available in 18k gold vermeil. Same design detail in a warmer finish. Both versions ship within 1-5 business days.
