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.

The average cardiac output of humans is 5.6 liters of blood per minute. If we do the math using the examples above, we see that 75 heartbeats per minute times 75 milliliters of blood pumped during each heartbeat equals the average cardiac output of about 5.6 liters of blood pumped through your heart each minute.
