Blackman 2 The salt treatments volume decreased at a faster rate in comparison to the control treatment. The water treatments volume increased between the 30-minute and 60-minute marks, then decreased between the 60-minute and 90-minute marks. The salt treatment best resembles normal kidney function while the water treatment does not. The urine volume increased rapidly for the water treatments because the kidneys were supplied with more water. In the kidney, the excess water was not reabsorbed, and so was excreted. The urine volume decreased for the salt treatments because more waster was reabsorbed in the kidney and the solute was excreted. ADH was involved in the process because it regulates and balances the water amount excreted. This regulation works to maintain normal kidney function

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
