DECLARATION BY THE CANDIDATE
ANATOMY OF RESPIRATORY SYSTEM
Ventilation: Ventilation of the lungs is carried out by the muscles of respiration.
Inhalation: Inhalation is initiated by the diaphragm and supported by the external intercostal muscles. Normal resting respirations are 10 to 18 breaths per minute, with a time period of 2 seconds. During vigorous inhalation (at rates exceeding 35 breaths per minute), or in approaching respiratory failure, accessory muscles of respiration are recruited for support. These consist of sternocleidomastoid, platysma, and the scalene muscles of the neck.
