[Bio1] Heart dissection lab reminders

Please visit your meat vendor ahead of time to ask about the availability and price of a pig’s heart. If buying the heart more than a day before the dissection, please freeze it to avoid an unpleasant experience. The night before dissection, place it in the refrigerator portion so that it will thaw. Do not bring a frozen heart to school during dissection!

You can take a look at this video to prep for the heart dissection on Thursday (Be, Cs) and Friday (Li). Bring your copy of the first SW with the drawing of a four-chambered heart on dissection day. This is how we will make the initial incision on dissection day, much like slicing a mango. The structures you will need to identify:

  • Chambers of the heart
  1. left atrium
  2. right atrium
  3. left ventricle
  4. right ventricle
  • Valves
  1. tricuspid valve
  2. bicuspid valve
  3. aortic semilunar valve
  4. pulmonic/pulmonary semilunar valve
  • Blood vessels
  1. aorta
  2. inferior vena cava
  3. superior vena cava
  4. pulmonary artery
  5. pulmonary vein
  • Other structures
  1. chordae tendinae
  2. interventricular septum
  3. papillary muscles
  4. trabeculae carnae
