the heart of pig

This was our middle-exam of biological experiment. We should recognize every blood vessels and understand the blood cycle. At first, we must got rid of the lungs. And, then, clean out all of the connective tissue, in order to make each vessel be identified easily. Finally, we cut it to be half. Because there were some questions about inside the heart. When we had confidence on all of blood cycle and structure, we had to ask TA to test us, two students one group. Fortunately, I cut the heart successfully and did the good exam. So happy!!!
