Order of cardis contration:
1. 2. 3.
pressure in the left ventricle rises rapidly then left ventricle pressure exceeds that in the aorta and finally the aortic valve opens, blood is ejected causing the blood pressure to rise
Increased heart rate delivers an ___ blood volume
___ plays an important role in the movement of blood throughout the vascular system
patients cardiac status
the heart pump generates the pressure to move the blood resulting in a ____ that travels rapidly throughout the system, demonstrationing a gradual transformation as it travels distally
pressure wave ( energy wave)
pumping acrion of heart results in high volume of blood in arteries to maintain a ___ between the arteries and veins
high pressure gradient
___ governs the amount of blood that enters the arterial system; arterial pressure and total___ determines the amount that leaves it
cardiac output
peripheral resistance
each cardiac contraction __ the arteries ehich serve as reservoirs to store some blood volume and potential energy supplied th the system
___ is greater at the heart, gradually decreasing as the blood moves further away. this __ difference is necessary to maintain blood flow
movement of any fluid medium between two points requires two things
apathway along which the fluid can flow and a difference in energy levels (pressure difference)
The amount of blood flow depends on
