terminology notes

Rector et al: One might be tempted to define 'heart valve' equivalently to 'valve in the heart', and 'valve' as a 'structure which functions as a valve'. But this combination results in the 'foramen ovale' being classified as a kind of 'heart valve', since it is undoubtedly located in the heart and functions as a valve
