Study Notes

Respiratory System

  • The normal value of expiratory reserve volume is 1.2 liters.
  • The volume of air that can be breathed per minute is defined as minute ventilation.
  • The normal value of inspiratory reserve volume is 3.3 liters.
  • The normal value of tidal volume is 0.5 liters.
  • The result of respiratory rate multiplied by tidal volume is minute ventilation.

Cardiovascular System

Electrocardiogram (ECG)

  • The ECG curve is a graphical representation of the heart's electrical activity.

Blood Pressure

  • The scientific name of the difference between systolic and diastolic blood pressure is pulse pressure.

Heart Sounds

  • The main cause of the 1st heart sound is the closure of the atrioventricular valves.
  • The main cause of the 2nd heart sound is the closure of the semilunar valves.

Electrocardiography

  • The apparatus that records the heart's electrical activity is called an electrocardiograph (ECG machine).
