UncleAl Posted June 3, 2005 Report Share Posted June 3, 2005 If you have a puckish sense of humor... center all the Tygon tubing on a cow heart from a butchershop. Four suction cups and two pairs of hands (do better mechanically) ought to get things moving. Have a few extra refrigerated cow hearts in inventory. Use water plus glitter to show flow. Practice your suturing or use SuperGlue. You need a stiff balloon or bellows in-line to level pressure fluctuations and smooth flow between beats. Elastic artery walls do that in vivo.

Boerseun Posted June 6, 2005 Report Share Posted June 6, 2005 Hahaha - made me think - my sister once did a similar project for her biology class years ago, and also had the idea of using a cow's heart. She did it rather rustically, and had a hosepipe connected to one artery which se subsequentially had to blow up to demonstrate the workings of the valves. In her presentation, she gave a little lecture, and proceeded to blow the hosepipe, which inflated the heart, which put pressure on the valve. Very spectacular, except for her not keeping in mind the strength of a dead valve compared to the pressure from living lungs...Needless to say, the valve popped, and the instructor was covered in heart-snot. That's the best description my sister could give, and I'm not sure what it was, but the heart was filled with a gelatinious substance which stank to high heaven. Shame. So, beware!Can't remember whether she got any points for it, though. Quote Link to comment Share on other sites More sharing options...

baratd Posted June 25, 2005 Report Share Posted June 25, 2005 Hello, I am doing a project for my 9th grade biology class where I have to build a working model of the circulatory /renal/any other topic or system. I am not sure where to start so I was wondering if someone could tell me how I could do thisThanks Aakriti Barat25/6/05 Quote Link to comment Share on other sites More sharing options...
