Pig Heart Dissection!

On Valentines Day

 (ironic I know! (: ) 

We dissected a pig heart!

Materials:

Pig Heart

Knife 

Pointer

Dissection Tray

Procedure:

Cut the heart in half (horizontal) 

Spread apart the heart so you can identify each part inside the heart

Parts of the heart: 

Aorta

Right/Left Atrium

Right/Left Ventricles

Interior/Inferior Vena Cava

Pulmonary Artery/Vein

Atrioventriclar Valve

Semilunar Valve

Mitral Valve

Tricuspid Valve

Below are some pictures of our procedure. 

Conclusion:

As we dissected the pig heart, we realized that the heart was very similar to ours. We share the same parts and it is relatively the same size. However, there were other people in the room the dissected a cow and sheep heart. These hearts differ in size. As you can imagine the cow heart is larger then a human and the sheep is slightly smaller. From this we can infer that the hearts (since they have the same parts and size) work the same. Therefore, this lab helped a lot because we could see the actual way a our heart works.
