kidney kidney NEPHRONS
Contains 5 components,
1. Bowman’s capsule – forming a blind-ending capsule around a knot of capillaries called the glomerulus (the site of filtration)
2. Proximal convoluted tubule (the site of bulk-phase reabsorption & some secretion)
3. Loop of Henle (where the concentration & dilution of urine mainly occur)
4. Distal convoluted tubule (the site of ‘fine-tuning’ reabsorption & more secretion)
5.
