5. Measuring with a ruler using the metric system. scopun enolichi
The image below shows examples of blood that has been spun in a centrifuge to separate
the red blood cells, white blood cells, and plasma. The percentage of blood which is composed of
red blood cells is called the hematocrit (HCT). It is an important lab value because it indicates
the blood's ability to carry oxygen to working tissues.
