Unformatted text preview: Nephrons filter 125 ml of body fluid per minute; filtering the entire body fluid component 16 times each day. In a 24 hour period nephrons produce 180 liters of filtrate, of which 178.5 liters are reabsorbed. The remaining 1.5 liters forms urine. Urine Production 1. Filtration in the glomerulus and nephron capsule. 2. Reabsorption in the proximal tubule. 3. Tubular secretion in the Loop of Henle. Components of The Nephron • Glomerulus: mechanically filters blood • Bowman's Capsule: mechanically filters blood • Proximal Convoluted Tubule: Reabsorbs 75% of the water, salts, glucose, and amino acids • Loop of Henle: Countercurrent exchange, which maintains the concentration gradient • Distal Convoluted Tubule: Tubular secretion of H ions, potassium, and certain drugs....
