3 Categories of Blood Cells Flashcards
What are the 3 categories of Blood cells?
- Red blood cell
- White blood cell
- Platelets
T/F. A medtech should identify the blood cells properly even when using a manual method and not always rely with machines when there’s a discrepancy. Make sure to apply proper staining and avoid contamination.
True
includes erythrocytes, leukocytes, platelets, and plasma
Whole Blood
small white layer of cells lying between the packed cell volume and plasma (leukocytes and platelets)
Buffy Coat
liquid portion of unclotted blood (Hazy and yellow)
Plasma
Use of anticoagulant to prevent clotting
Plasma
fluid that remains after coagulation (Clear and straw colored)
Serum
Use of non-anticoagulant tube since we let the blood to clot
Serum
Anucleate, biconcave, discoid cells filled with a reddish protein (Hb/Hgb)
RBC
Measure 6-8 um in diameter with a zone of pallor that occupies one third of their center
RBC
function of RBC
Transport oxygen and carbon dioxide
Hemoglobin, Hematocrit, RBC indices
RBC
disease that insufficient or lack of enough healthy RBC that reflects if low in count of hgb, hct and other blood indices
Anemia
T/F. Causes of Anemia
▪ There is a problem in the production of RBC in the bone marrow
True
T/F. Causes of Anemia
▪ Progenitor cells can travel to the peripheral because they are destroyed along the way
False, the progenitor cells cannot travel
production of too much red blood cells in the bone marrow
Polycythemia vera
Makes the blood thicker because of increase in number that can lead to organ failure
Polycythemia vera
Loosely related category of cell types dedicated to protecting their host from infection made by bacteria, viruses, parasites and fungi and injury
WBC
Enumerate the agent of the immune system
o Skin
o WBCs
o Plasma cells, NK Cells, Macrophage, cytokines
outer layer; first barrier and line of defense
Skin
second line of defense
WBCs
third line of defense
Plasma cells, NK Cells, Macrophage, cytokines
low/decrease number of WBC → prone to many disease
Leukopenia
high/increase number of WBC → can be identify with differential count
Leukocytosis
cancer of the blood involving the bone marrow and the lymphatic system
Leukemia
Enumerate the types of leukemia
▪ Acute Lymphocytic leukemia
▪ Acute Myeloid leukemia
Blood components that affected by Leukemia
- Neutrophils – Bands
- Eosinophils
- Basophils
- Lymphocytes
- Monocytes
Maintain blood vessel integrity by initiating vessel wall repairs
PLATELETS
Main function of platelets
to stop the bleeding (Hemostasis and thrombosis)
Platelets is responsible for
Adhesion, Secretion, Aggregation
primary hemostasis
White thrombus
