Answer
To carry out the dissection, I placed the heart with the ventral side up to identify the left and right sections. I then made an incision to expose the left ventricle and right ventricle, ensuring to pin back any structures for better visibility, while taking safety precautions.
Step 5
Draw a diagram of the dissected heart and on it label the following: bicuspid valve, left ventricle, right atrium, tricuspid valve.

In the diagram of the dissected heart, the following should be labeled:
Bicuspid Valve (also known as the mitral valve)
Left Ventricle
Right Atrium
Tricuspid Valve.
Ensure that the labels are clear and properly placed on the respective parts of the heart.
