Respiratory pathway from external air to trachea
Nares -> Vestibule -> Nasal Cavity -> Nasopharynx -> Oropharynx -> Laryngopharynx -> Larynx -> Trachea
Respiratory pathway from trachea to alveolar sacs
Trachea -> Primary Bronchi -> Secondary bronchi -> Tertiary bronchi -> Bronchioles -> Terminal bronchioles -> Alveolar Ducts -> Alveolar sacs
What part of the conducting pathway of the respiratory system has no cartilage and only smooth muscle?
Bronchioles
What is the final segment of the conducting pathway?
Terminal bronchioles
What part of the conducting pathway can perform respiration in some cases?
Respiratory bronchioles which are just bronchioles with an alveolus
What are alveolar type 1 cells?
Simple squamous epithelia specialized for rapid diffusion
What are alveolar type 2 cells?
Alveolar cells that produce surfactin
What is the purpose of surfactin?
Prevents the lungs from collapsing
What is eupnea?
relaxed or resting breathing
What is hyperpnea?
Forced breathing
A) Inspiratory Reserve Volume
B) Tidal Volume
C) Expiratory Reserve Volume
D) Residual Volume
