Heart Dissection

For your observations, you will need to post some pictures - use the iPads to label the following external anatomy.  Use as many pictures as you need to show the following structures clearly:

• Left ventricle
• Right ventricle
• Left atrium
• Right atrium
• Apex (the bottom point of the heart)
• Aorta
• Superior &/or Inferior vena cava
• Pulmonary veins
• Pulmonary trunk &/or arteries
• Coronary Blood Vessels (on the surface of the heart)

Internal Anatomy:

Once you have made the cuts into the ventricles of the heart locate, takes pictures of and label the following structures from the inside:

• Left & Right Atria and Ventricles
• Septum
• Right & Left AV valves
• Pulmonary semi lunar valve
• Aortic semi lunar valve
• Chordae Tendinae

Answer the following questions about the structures and functions of the heart & post to your blog:

1. Compare the structure of the atria and ventricles - how are they different?  Why is that?
2. Did you notice a difference between the veins and arteries entering and leaving the heart?  How is their structure different?
3. Describe the valves that you found in the heart - what are their functions?
4. What surprised you about dissecting the heart?  Why?
