'Cause I'm The Cool Aunt

Autobot asked me to join her for her sheet sheep (thanks Rach) heart dissection at school last week, and because I'm the cool aunt, of course I went.  And because I'm a blogger at heart, I took the camera.

The first tentative touch - eeewww

Finding the aorta - the opening goes all the way to the bottom of the left ventricle.

Where do we cut?

Apparently, sixth graders are not trustworthy with scalpels, but they're allowed dull scissors to cut their hearts with.

The left ventricle, bicuspid (mitral) valve and the left atrium.
Those stringy-things?  Yeah, those are your chordae tendonae - your heartstrings - so next time something tugs on your heartstrings, you know what they look like.
(Sorry, sometimes my science nerd comes out.)

Though I'm still wondering what kind of animal a "sheet" is? hee hee

And thank you very much for taking me right back to Freshman Biology. Glad you are better at that stuff than me!

Hey Diva does it speak of some *serious* oddities in my make up if I can read this post, check it out thoroughly, all the while eating brown rice with slow simmered beef tips and a thick brown gravy over it?

;) You're a cool Aunt. Autobot is a lucky (and cute) kid!

I don't like it, I don't like it, I don't like it, I don't like it, I don't like it, I don't like it, I don't like it.

You ARE the cool aunt and your niece is a badass.

I would've dry heaved my way to the playground.
