Explanation:

Complete Question

What would be the effect on urine output if sodium channels in the tubule cells were inhibited?

A) The volume would increase.

B) The volume would decrease, then quickly resume.

C) The volume would decrease by one-tenth the sodium concentration.

D) The volume would decrease by half the sodium concentration

Solution -

If the glomerular filtrate is directly allowed to flow into the urinary bladder without passing through the reabsorption tubule, then the amount of loss of fluid through urine will increase.  

The reabsorption tubule absorbs the necessary substances from the filtrate and allows blood stream to dispose of their waste substances thereby converting the filtrate into urine. It is to be noted that here that nearly 70 % of the sodium is absorbed in the in the reabsorption tubule (proximal tubule) in the form of sodium bicarbonate and sodium chloride

Option A is correct
