- Distal convoluted tubule
When water reabsorption increase, what happens to urine osmolarity and urine volume?
- osmolarity decrease, volume increase
- osmolarity increases, volume decreases
- osmolarity and volume decrease
- osmolarity and volume increase
Osmolarity increase, volume decreases
when water returns to blood and not going to urine
- volume decreases
- osmolarity increases

As hydrogen phosphate accepts H+ in the Tubular fluid and most os converted to dihydrogen phopshate
- pH doesnt change
- pH increases rapidly
- pH decreases rapidly
pH decreases rapidly
