Chapter 20 cont’d * 2-3 questions on exam 2  The Energy for Cardiac Contractions        Aerobic metabolism        -  Fatty acids        -  Glucose        -  Oxygen from circulating hemoglobin stored in myoglobin The Cardiac Cycle        One heartbeat        -  Contraction and relaxation of each chamber       Each chamber has two phases        -  Systole (contraction)         -  Diastole (relaxation) * Fluids move from higher to lower pressure  - When pressure gradient present        Blood pressure in any chamber        -  Rises (move blood)         -  Falls (blood flow in)        -  Alternate movement in and out       Blood flows from high to low pressure (repeated)        -  Timing of contractions and one-way valves        Phases of
