Flashcards in Hemotology Deck (70)
Inability to clot
Sites of stem cell production in adults
Difference between serum and plasma?
Plasma still has the clotting factors while serum is plasma without the clotting factors.
An immature RBC
What drives the body to create new RBC (erythropoiesis)?
Hypoxia ( decrease o2) reaches the kidneys which release erythropoietin, which stimulates the red bone marrow, which causes erythropoiesis (creation of RBC).
What is Hypoxia?
Not enough O2 in the body
Values for significant elevated WBC
Function of blood?
O2, CO2, Hormones, waste, food
Clotting, phagocytosis, antibody production
-DISTRIBUTION OF BODY HEAT
granules contain heparin, seratonin, histamine, released for allergic or inflammation response.
defense against parasites
2nd responder to neutrophils, stay longer, increase with all types of infection
B & T cells, More for autoimmune and cancer,
physical appearance of the cell
Less than 20,000 platelets
risk for spontaneous bleeds
Less than 5,000 platelets
watch out for petechiae (red dotted rash) and ecchymosis (bruising)
Vasoconstriction, Vasospasm, platelets are activated and become sticky, unstable clot
Make unstable clots more stable
What are the three pathways in the clotting factors?
Intrinsic, Extrinsic, Common pathways
