PPT-Packed cell volume (PCV) also called hematocrit (HCT)

is defined as the percentage of the volume occupied by RBC to the whole blood volume The packed cell volume PCV can be used as simple screening test for anaemia The PCV is about three times the .

Team Competition. The Cell Cycle. Why the cell must divide:. Reason 1: . The cell only contains one copy of DNA to serve as the instructions for everything that occurs in the cell. If the cell were too large it would not be capable of providing instruction for all necessary functions.. The hematocrit value indicates the volumetric proportion of red blood cells in the blood. Centrifugation is the reference method for the determination of this value. It is used to separate the cellula 1. The _____ states that all cells come from previously existing cells.. 2.

The heart is actually two separate pumps, (right heart) that pump blood through the lungs and (left heart) that pumps blood through the peripheral organs.. Each of these two pumps is in turn comprised two chambers, an (atrium) and (ventricle). Located between atria and ventricles on both sides of the heart are (. Haematocrit. (HCT).
