Marginalism is a theory of economics that attempts to explain the discrepancy in the value of goods and services by reference to their secondary, or marginal, utility. The reason why the price of diamonds is higher than that of water, for example, owes to the greater additional satisfaction of the diamonds over the water.
A large amount of circulating blood flows through the kidneys. Approximately 25% of the cardiac output or 1200 ml of blood per minute is received by the kidneys. One liter of urine is the end product of more than 1000 liters of circulating blood processed through the kidneys. large amount of circulating blood flows through the kidneys.

Urinary System: Physiology & Urine Formation. I). Volume of blood filtered. Kidneys are 1% of body weight and use 20-25% of the oxygen. Â¼ of the cardiac output is delivered to the kidneys each minute (cardiac output is the amount of blood pumped out of the ventricle each minute) a regular bottle of water contains about 590 ml. 1000 to 1200ml of blood go through each glumeruli of each nephron every minute. (2 water bottles) Equals 650 ml of plasma (blood cells cannot be filtered) 1/5 of this goes through the renal tubules. (130 ml of filtrate) The entire plasma volume is filtered 60X a day or 180 liters of water per day. (304.6 water bottles per day) Not all of the filtered material is excreted.
