Explain.Label the steps involved in vasopressin activation of water reabsorption.Part ADrag the labels onto the diagram to identify specific steps in vasopressin activation of water reabsorption across the collecting duct epithelium.Renal tubules cannot reabsorb HCO3–; yet HCO3–concentration in the tubular fluid falls while in the blood plasma itrises. Explain this apparent contradiction.
