PROPERTIES OF VASCULATURE Flashcards
takes blood from the heart and distributes it to the tissues
arterial system
returns blood from the tissues of the heart
venous system
separates the arterial and venous systems and is the site where nutrients and cellular waste products are exchanged between blood tissues
microcircularion
_________- law describes the laminar flow of fluids through cylindrical tubes and in terms of pressure the dimensions of the tube and viscosity of liquid
Poiseulle’s law
resistance is highest in the ________ and it diminishes as the vessels increases in ______________ on the arterial and venous sides of the capillaries
capillaries
diameter
the volume of blood ejected by each ventricular contraction
stroke volume
_________ the ratio of blood volume to mean blood pressure , also affects pulse pressure
arterial compliance
load that stretches the cardiac muscles before contraction
work placed upon myocardium before contraction during diastole
preload
degree of vascular resistance to ventricular contraction
afterload
