  1. Experiment Questions Heart Dissection

  2. Heart Dissection Describe how you dissected a mammalian heart in order to investigate the internal structure of atria and ventricles. Identify sides or front/back / how identified / ventral side uppermost / on board or dish /named cutting instrument / described location of cut / safety procedures stated e.g. gloves, goggles, white coat

  3. Heart Dissection State the procedure that you followed to expose a semilunar valve. Cut aorta or cut pulmonary artery

  4. Heart Dissection Where in your dissection did you find the origin of the coronary artery? Aorta or near semilunar valve

  5. Heart Dissection Describe the steps that you followed in order to identify and display the inner structures of the heart. Identify front or back or left or right / how identified / named cutting instrument / location of first cut / second cut described / locate, find or flag label named structure / safety precaution described

  6. Heart Dissection What did you do in order to expose a semi-lunar valve? Cut open aorta or cut open pulmonary artery

  7. Heart Dissection What instrument did you use for the dissection? Scalpel / blade / scissors / knife

  8. Heart Dissection Describe how you carried out the dissection. Ventral side up / identify left or right / section or words to that effect / expose left ventricle / expose right ventricle /section to show aorta / pinning back / safety precautions

  9. Heart Dissection How did you expose the semi-lunar valves when dissecting the sheep’s or ox’s heart? Cut (open) the aorta or cut (open) the pulmonary artery
