 Practice Mid-Term Lab Practical

A Very General Description of What You Should Know:
Lab 1: 
  • cardiac muscle slide
  • heart models and diagrams
  • dissection of sheep heart
  • PhysioEx 34B Frog Cardiovascular Physiologyheart modifiers (computer simulation)
Lab 2: 
  • anatomy of conduction pathway of the heart
  • Biopac L05-ECG-1:  normal electrocardiogram (including the names of all waves, intervals, and segments, what they mean, and how they correlate to parts of the cardiac cycle)
Lab 3: 
  • slide of artery, vein, and capillaries
  • circulatory tree model
  • arm blood vessels model
  • vessels on torso, thorax, and pelvis models
  • auscultating heart sounds
  • palpating superficial pulse points
  • Biopac L07-ECG-Pulse:  ECG and pulse (including effect of cold temperature and raising arm (gravity) on pulse amplitude)
  • taking apical pulse
  • Biopac L017-HS-1:  ECG and heart sounds (identify 1st and 2nd heart sounds and know what causes them, know where systole and diastole are)
Lab 4: 
  • Biopac L016-BP-1:  blood pressure measurement (identify Korotkoff sounds and know what causes them, be able to determine systolic, diastolic, pulse, and mean arterial pressures)
  • PhysioEx Cardiovascular Dynamics 33B:  vessel resistance and pump mechanics (computer simulation)
Lab 5: 
  • blood slide (be able to differentiate red blood cells, platelets, neutrophils, lymphocytes, monocytes, eosinophils, and basophils)
  • differential WBC count
  • identify abnormal blood smear slide as leukemia
  • identify abnormal blood smear slide as sickle cell anemia
  • lymph node slide
  • lymphatic vessels on charts and models
  • blood typing (ABO and Rh systems)
  • interpret hematocrit
