The Heart

Last week when I was at school I got to dissect a Pig's Heart in science class. First we had to cut it in half but not all the way  so we could see the four chambers, left and right atrium, left and right ventricles. Then we took  both of the atrium out of the heart so we could get a better view of it. I poked the top of the heart and it was very squishy like there was something alive in the heart. I even took pictures of  it with my phone camera.
