    Heart Dissection Documentation

    1. Carefully photograph your dissected heart specimen from various angles.
    2. Compile your photographs or illustrations into a single document. Insert this document as an attachment for submission.
    3. Make sure all labels are clear and legible in the images.

    Key structures that need to be labeled on the dissected sheep heart

    • Bicuspid valve
    • Tricuspid valve
    • Interventricular septum
    • Left ventricle, Right ventricle
    • Right auricle, Left auricle
    • Chordae tendineae
    • Left myocardium
    • Right myocardium
    • Pulmonary trunk
    • Aorta
    • Papillary muscles

    Clean up

    • Specimen Disposal - Gather all sheep heart tissue, fat, place them in a designated biohazard bin.
    • Tray Cleaning - Clean and rinse dissection trays; dry with paper towels. Return trays to the cart.
    • Discard paper towel in the regular trash can.
    • Tool Cleaning - Rinse all dissection tools (scalpels, scissors, probes, tweezers) thoroughly with water to remove tissue and fat, then wash with soap or disinfectant.
    • Return tools to storage tray.
    • Surface Decontamination - Wipe down work surfaces, benches, and sinks with a disinfectant solution or approved sanitizing wipes.
    • Personal Clean-Up
      • Remove gloves by turning them inside out; dispose of them in the approved waste bag.
      • Remove aprons and goggles; clean reusable items as directed.
      • Thoroughly wash your hands with soap and water after finishing all clean-up steps

    Heart Dissection: Post-Lab Peer Dialogue

    1. How can you tell which side of the heart is the anterior surface and which side is the posterior surface?
    2. Which chambers are the pumping chambers of the heart?
    3. From where in the body does the blood entering the superior vena cava come? Inferior vena cava?
    4. How do the walls of the atria compare with the walls of the ventricles and why are they different?
    5. What is the purpose of heart valves?
    6. What are the names of the blood vessels that carry blood away from the heart, and those that carry blood toward the heart?
    7. Which artery is the largest and why?
    8. What is the purpose of the coronary artery and what results if there is blockage in this vessel?
    9. Can an artery carry deoxygenated blood? Please explain.
    10. In what ways did the hands-on experience enhance your understanding of the heart compared to theoretical learning?
