- Renin-angiotensin-aldosterone Made Simple
The body has many systems that work together in order to maintain homeostasis. The renin-angiotensin-aldosterone pathway is no different. It has 3 functions: (1) to maintain a proper blood pressure/blood flow, (2) to maintain the right concentration of...

hematocrit
Term: hematocrit or packed cell volume (PCV)
Origin:
????/haema(=blood)
??????<judge > ????? (verb) / (=judge, separate, decide, accuse)
à to separate the blood. Coined: ?
Hematocrit originally was used to describe the procedure used to separate blood into packed erythrocytes(PCV), buffy coat layer and plasma. Today the term hematocrit is synonymous to major blood component PCV. When a small capillary tube used to separate blood components it became microhematocrit.
Definition:
The percentage of blood volume that is occupied by red blood cells to the volume of whole blood in a sample of capillary, venous, or arterial blood.
