Welcome to Biology 2021!
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 Physiology: heart 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
