What controls the production of platelets? | Thrombopoietin |
When an injury is sustained to a blood vessel, platelets move to that site: T/F | True |
What is thrombopoietin? | A protein manufactured by the liver, the kidney, smooth muscle, and teh bone marrow. |
The release of thrombopoietin is controlled by : | The number of platelets present in the blood |
CBC Complete blood count: | Measures the red cell count, white cell count, platelet count, hemoglobin, hematocrit, and priovides a detailed description of the types of WBCs in the sample |
What can a CBC indicate? | Anemia, leukopenia, and thrombocytopenia; also it can indicate if the levels of any of the types of WBCs are abnormal ( which may indicate leukemia) |
Leukopenia | Low number of white blood cells |
