B. Na+ reabsorption in the proximal tubule.
C. Transcellular transportation in the distal convoluted tubule.
D. K+ reabsorption in the proximal
The major action of ADH in the kidneys is to:a. increase water absorption by the proximal convoluted tubule.b. increase glomerular filtration rate.c. increase water reabsorption by the collecting duct.d. increase potassium’s excretion.
The concentration of water in the luminal fluid at the end of the proximal tubule is nearly always the same as:
