Formed Elements |
Not true cells The 'red' part of blood. This is the platelets, red blood cells, and white blood cells |
|
|
Plasma |
The liquid matrix 6 parts: electrolytes water gases proteins waste nutrients |
|
|
Hematocrit |
A measurement of the percentage of blood that is Formed Elements. Usually tested with a centrifuge, a device that spins a tube until the heavier stuff (formed elements, in this example) move to the bottom. The percentage of formed elements is the Hematocrit Normal is ~38% in women, ~45% in men |
|
|
Anemia |
Low Hematocrit |
|
|
Polycythemia |
High Hematocrit |
|
|
Hemopoiesis / Hematopoiesis |
The production of Blood Cells |
|
|
Erythropoiesis |
The production of Red Blood Cells |
|
|
Leukopoiesis |
The production of White Blood Cells |
|
|
Thrombopoiesis |
The production of platelets |
|
|
Hematocytoblast |
The stem cell that becomes blood cells |
|
|
Erythroblast |
A Hematocytoblast becomes an erythroblast to ultimately become a red blood cell. These cells make hemoglobin until they are ~34% Hb and then all the organelles start to die. It keeps the ribosomes and becomes a reticulocyte. |
|
|
Reticulocyte |
After the erythroblast loses most of it's organelles it becomes a reticulocyte and is released into circulation. It will mature into a RBC in about 2 days 1-2% of formed elements is reticulocytes, so this can be a diagnostic tool |
|
|
Erythrocyte |
Red Blood Cell Makes up 95% of formed elements (the ratio of RBC to others is 700:1) |
