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

list the agranular leukocytes

monocytes and lymphocytes

What cell type makes up the majority of WBC

neutrophils

Which antibodies would you find in the plasma of a person with type AB blood?

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
