Exercise 3: Urine Analysis Water (500 ml water) 60min 120min 60 120 Omin 0 omin Water (1000 ml water) 60min 120min 180 480 Volume (ml) 0 1 = 60/60 2 = 120/60 3 = 180/60 8 = 480/60 Urine production rate (ml/min) Specific Gravity (SG) 1.03 1.03 1.02 1.03 1.02 1.01 Data P. 1

Answer 1

Urine production rate of 500ml water vs 1000ml water Urine production rate (ml/min) urine production rate of 500ml water Urine production rate of 1000ml water 0 min 120 min 60 min Time (min)

Specific gravity of 500ml water vs 1000ml water 1.035 1.03 1.025 Specific gravity (SG) 5 Specific gravity-500ml Specific gravity-1000ml 1.005 1 O min 120 min 60 min Time(min)

The subject 1- 500ml water intake has higher specific gravity at each time point compare to the Sunject-2 1000 ml water intake.Higher specific gravity shows the less diluted urine due to availibilty of less water to the kidney.

Urine production rate is higher in subject-2 1000ml compare to the subject -1 500ml. Urine production rate depends on the intake of water i.e water passing through kidney is higher causes more urine production. Kidney has efficient mechanism to maintain homeostasis of the salt -water balance in body,
