While traveling through the rain forests of Peru, you are introduced to a rare and exotic plant. You discover that it contains a
toxin that blocks the reabsorption of sodium ions from the proximal tubule. If administered, what affect would this toxin have on the reabsorption of water and other electrolytes? While traveling through the rain forests of Peru, you are introduced to a rare and exotic plant. You discover that it contains a toxin that blocks the reabsorption of sodium ions from the proximal tubule. If administered, what affect would this toxin have on the reabsorption of water and other electrolytes? The toxin would significantly decrease the amount of water reabsorbed but would significantly increase the number of other electrolytes reabsorbed by the proximal tubule. The toxin would significantly increase the amount of water absorbed and the electrical gradient for reabsorbing chloride. The toxin would significantly decrease the amount of water and certain electrolytes reabsorbed by the proximal tubule. The toxin would significantly increase the amount of water and calcium ions reabsorbed by the proximal tubule.
The proximal tubule is very important to the maintenance of homeostasis in the renal microenvironment. The alterations of the physiological functions will therefore distort the reabsorption of other ions. The blockage of sodium reabsorption into the channel will leads to an hypotonic internal environment. This will afterward leads to reduction of the reabsorption of water into the organ and increase the reabsorption of other ions into it. This will have clinical effect on the organism. Which is oedema of the extracellular surrounding of the tubules through accumulation of fluids and could lead to imbalance in neurological sense due to the imbalance in other ions.
