Any experts on Vintage Games?

With the holidays upon us, I've been trying to think of unique gifts for my family. When I was younger (mid 80's...yes I know I'm still young) I remember my mother had this "game" in which it gave you all the pieces to put together a model of a pumping heart. I'm not sure whether she had it before I was born, or got it when I was really young. In other words, it could be from the 70's or 80's. I've gone on ebay and looked under both categories with no luck. I know there's a very slim chance I will find this, considering the fact that I'm not sure many other people other than my family would buy this "game" and think it fun. If this is ringing any nostalgic bells for anyone, please, I would love to know the name of it, and possibly where I could buy it again for my mom! Thanks!
