Order of Flow

100

Lowest oxygen saturation in the body

Coronary sinus

200

Receives unoxygenated blood from veins below the diaphragm

IVC

300

Acts as a reservoir and assists in RV filling

Right atrium

400

This valve is situated between the RA and RV.  It sits closer to the apex than the MV.

Tricuspid valve

500

The most anterior chamber of the heart.

Right ventricle

Diastolic Function

100

The time in the cardiac cycle where the ventricular pressure and wall thickness decrease, volume remains the same and atrial pressures rise

IVRT

200

Diastole consists of 3 stages: ________, ________, and _________.

Rapid early filling, diastasis and atrial kick

300

Defined as the failure of the ventricle to relax and allow normal filling.

Diastolic dysfunction

400

The stiffer the ventricle, the less compliant it is; this is an __________ relationship

Inverse

500

__ __ __ __ __ reflects ventricular pressure after filling is complete.

LVEDP

Systolic Function

100

The segment from mitral valve closure to aortic valve closures

Systole

200

Systole is also referred to as ventricular __________.

Depolarization

300

There is a _______ in ventricular size and _______ in pressure resulting in ejection of blood.

decrease, increase

400

Increased preload leads to chamber __________

Dilatation

500

Defined as increased myocardial fiber length means increased tension

Frank-Starling Law

Math
