  • Arteries
    Carry blood away from the heart
  • Veins
    Carry blood toward the heart
  • Cardiac Cycle

    1. Atrial and ventricular contraction
    2. Atrial and ventricular relaxation
  • Electrical activity of the heart
    1. Muscle contraction occurs through electrical stimulation
    2. Depolarization
    3. Repolarization
  • Cardiac Output (CO)

    Amount of blood pumped by the heart per minute (mL/min)
  • Heart Rate (HR)
    Number of heart beats per minute (bpm)
  • Stroke Volume (SV)
    Volume of blood pumped per beat (mL/beat)
  • CO
    HR x SV
  • Normal heart rate
    • 60-100 bpm
  • Tachycardia
    Heart rate > 100 beats per minute
  • Bradycardia
    Heart rate < 60 beats per minute
  • Normal Cardiac Output
    • 4200 – 7000 mL/min
    • 4.2-7.0L/min
  • Skeletal muscle pump
