WebReabsorption and Secretion in the PCT. Largest amount of solute and water reabsorbtion. Secretes variable amouts of H+, NH4+ and urea. Most solute reabsorption uses Na+. Na+/H+ antiporter cause Na+ to be absorbed and H+ to be secreted. Solute reabsorbtion promotes osmosis- creates osmotic gradient. WebSo, the glomerular filtrate concentrates as it moves down through the descending limb. Reabsorption is minimum in the ascending limb. This limb is impermeable to water but electrolytes can be transported actively or passively. So, as the concentrated filtrate moves upward it gets diluted due to the passage of electrolytes to the medullary fluid.

WebThe solution was then filtered to remove the catalyst by passing through a bed of Celite, and the bed was washed with dichloromethane. The filtrate was concentrated under reduced pressure to viscous oil, and hexane was added to give a yellowish-white precipitate of the diamine (yield: 0.8 g [96%], mp 196°C–198°C). WebA. has a higher concentration of waste products (urea) than the original filtrate. B. may have lost up to 99% of its original volume. C. is called urine. D. has a higher concentration of waste products (urea) than the original filtrate, may have lost up to 99% of its original waste, and is called urine. E. None of these choices is correct. WebThe tubular filtrate becomes hyperosmolar (concentrated) under the action of ADH in the collecting tubules. For ADH to effectively allow water absorption, a medullary interstitial concentration gradient must be established by NaCl absorption without water in the ascending limb and the vasa recta. ir 2020 download
