| Liam is a body builder and frequently consumes protein powder as part of his fitness regimen. He consumes more protein than his body actually uses. What happens to the excess protein? It is filtered through the glomerular capillary into the glomerular capsule and into the nephron, where it is finally excreted in the urine. It is broken down into urea by the liver, which is then filtered into the glomerular capsule as well as secreted elsewhere in the nephron. | show 🗑

|
||||
| What is the function of the countercurrent mechanism in the nephron? It creates a highly concentrated interstitial fluid so that urine can be concentrated by the collecting ducts. It is a method to transport sodium in order to control sodium concentration in the blood. It keeps the volume of water lost in the urine relatively constant. It keeps interstitial fluid hydrated to maintain blood pressure. | show 🗑
