प्रश्न
When a molecule or ion is reabsorbed from the lumen of the nephron, where does it go? If a solute is filtered and not reabsorbed from the tubule, where does it go?
उत्तर
When a molecule or ion is reabsorbed from the lumen of the nephron, it goes to the blood stream through efferent arteriole which carries blood away from the glomerulus. If a solute is filtered and not reabsorbed from the tubule, it goes along with urine.
