Lab 3: Pig Heart
Dissection
and Human Heart Models |
A. Pig Heart Dissection
Working in groups of two
or three, and using the instructions
provided, dissect a pig heart. You will need
to use gloves as these hearts are preserved in a preservative
solution. The various structures that you will need to know will
be hyperlinked. |
