Question

Describe briefly the changes from the control values in the MEAN values for volume, specific gravity and NaCl after drinking pure water. Based on the specific gravity measurements, is the urine isosmotic, hyperosmotic or hypoosmotic to the fluids of the body. Explain using physiological relevance.

Answer 1

As specific gravity is defined as weight per unit volume,so urine is the less dense fluid,so urine will be in hyperosmotic category.
