Cow Heart Dissection
A. Background Information When the class dissected the cow heart last Thursday there were a lot of different things that could be seen. The purpose of this particular dissection was to see how the heart worked and pumped blood so that the body was able to receive the nutrients and oxygen it needed to survive. The cow heart and a human heart are alike in many ways, based on the same structures and how the blood goes in and out of the heart. However, the cow heart is so much bigger than the human heart. In this lab, there will be more detail on what was seen and how the dissection works.
B. Materials
1. Cow heart
2. Surface to cut on
3. Scalpel
4. Poker stick
5. Gloves
6. Paper towels
7. Pen
8. Paper
9. Scissors
C. Procedure
1. Put gloves on.
2. Take cow heart out of the bag and place it on the surface area you are using.
3. Put the heart so that when you look down the left side is on the left and the right side is on the right.
4. Observe the outside of the heart and record what you see.
5. Cut open the right side of the heart, using the scalpel or scissors, so that you can see the different structures that are on the right side
6. Observe and write down what you see.
7. Use the poker stick to push your way through the openings in the right side, like the right ventricle, superior vena cava, inferior vena cava, and the pulmonic valve.
8. Cut open the left side of the heart using a scalpel or scissors, so that you can see the different structures that are on the left side like the aortic valve and the let pulmonary veins.
9. Finish observing the inside of the heart.
10. Clean up; throw away the heart, clean off the tools used, and disinfect the area used for the dissection.
D. Observations
During the lab, Hannah and I had quite a few observations. First off, majority of the
