Questions and Answers
Glomerulus filters blood and produces liquid isotonic with plasma, where fluid enters the proximal tubule for reabsorption. This process begins in the loop of Henle where approximately 80-85% of the water is reabsorbed along with electrolytes and other small molecules. In the distal tubule, secretion of water and other materials occurs, resulting in fluid that is isotonic with plasma. In the collecting duct, fluid concentration happens, resulting in urine formation with higher solute content compared to plasma. About 60-70% of Na+ filtered by the glomerulus is reabsorbed in the ______.
proximal tubule
HCO3 formed within the tubule cells moves back in circulation with Na+, while protons are excreted. 25% of the filtered load will be reabsorbed by the loop of Henle where Cl- will transport with Na+ as it returns to the bloodstream. In the distal tubule, hormonal regulation and Na+, K+, and proton interchanges determine the ultimate amount of Na+ retained by the body with K+. Almost all K+ filtered by the glomerulus is reabsorbed in the ______.
proximal tubule
K+ that is eliminated from the body is lost by secretion in the ______.
