What is the rate at which blood passes through the kidneys?
The blood flows through both the kidneys of an adult weighing 70 kg at the rate of about 1200 ml/mt. The portion of the total cardiac output (about 560 ml/ mt.) which passes through the kidneys is called the renal fraction. This is about 560/1200 ml per minute, i.e., about 21 per cent.
What is the rate of urine formation in the kidneys?
The rate of formation of the primary urine is 120 ml/minute, while the rate of urine passing to the bladder under the same condition is 1-2 ml/ minute.
