The Central Intelligence Agency is responsible for the intelligence gathering, processing, analysis and reporting procedures conducted throughout the world outside of the United States. The agency monitors (watches) and determines if there are issues of interest occurring in the world.
A typical adult has a blood volume of approximately 5 liters, with females generally having less blood volume than males. Blood volume is regulated by the kidneys. B V = P V 1 â H C {\displaystyle BV={\frac {PV}{1-HC}}}. Blood volume measurement may be used in people with congestive heart failure, chronic hypertension, renal failure and critical care. The use of relative blood volume changes during dialysis is of questionable utility.
Every day, close to 200 liters of blood is processed and filtered by the kidneys. The extracted waste products and excess water form urine, which is eventually expelled from the body via the urinary tract. This entire process of extracting waste products and excess water from the blood takes place in the nephrons.
