What happens to urine concentration and volume when a person is dehydrated? (Please explain what specifically occurs in the kidneys)
A patient’s GFR is 125 ml/min, and his urine is produced at a rate of 1.25 ml/min. (A) By what factor is the inulin concentrate in his urine. (B) The concentration of glucose in his plasma is 5 mmol/l. His renal reabsorption of glucose is completely inhibited. What would be the concentration of glucose in his urine.
Is glucose always present in the urine of normal individuals? Explain your answer.
