T/F: Kidney Failure is associated with Anemia
True anemia of chronic renal failure
T/F: the number of RBC and platelets is unsteady in the blood, depending on invading pathogens and other foreign antigens, while that of white blood cells is pretty steady
False WBC count also varies dramatically
What plasma protein plays a role in blood clotting?
Fibrinogen
positive chemotaxis
WBC being attracted to chemicals
define phagocytosis
WBC engulfing pathogens and cell debris
amoeboid movement
WBC movement through the endothelium and into peripheral tissues
Which hormone stimulates the proliferation of red blood cells in red bone marrow?
erythropoietin (EPO)
T/F: Formed Elements are made up of almost entirely WBC's.
false
T/F: The vast majority of Oxygen is carried dissolved in Plasma.
false only 7% is carried in plasma
T/F: Warfarin (a drug that thins the blood) works by promoting the formation of vitamin K dependent clotting factors
false blood thinners do not promote blood clot formation
The process by which the formed elements of the blood develop is called
hemopoiesis
lymphocyte function
involved in immune response
define diapedesis
migration of WBC out of circulation

monocytes and lymphocytes
What cell type makes up the majority of WBC
neutrophils

neutrophil function
phagocytize bacteria
monocyte function
phagocytosis, develop into macrophages in the tissues
eosinophil function
play a role in allergies and asthma
basophil function
release histamine, and other mediators of inflammation
