Mnemonics - Blood flow through heart valves

One quick and easy way to remember the path blood takes through the valves of the heart:

TRIPS BIAS

TRIcuspid

Pulmonary

Semilunar

BIcuspid

Aortic

Semilunar

Note that it's the two "cuspids" that are represented by more than one letter. Usefully, the TRIcuspid takes 3 letters while the BIcuspid takes 2. If you remember that, you won't get tripped up trying to remember extra, imaginary valves! :-D
