A human drinks 1000 CM3 of distilled water and measures the amount of urine passed at 30 minute intervals. The subject passes 175CM3 at 30 mins, 325CM3 at 60 mins, and 225 CM3 at 90 mins. Why does the subject pass more urine at 60 mins than 90 mins???© BrainMass Inc. brainmass.com February 24, 2021, 2:20 pm ad1c9bdddf
Before we look at your actual numbers, let's define some terms and just look at urine homeostasis. I do not know exactly which of these mechanisms you have been studying, so you will need to decide that.
