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.
Red blood cells (RBCs) typically make up roughly 37% to 49% of the volume of blood. Since a hematocrit is often performed as part of a complete blood count (CBC), results from other components, such as RBC count, hemoglobin, reticulocyte count, and/or red blood cell indices, are taken into consideration.
