- - - - Rectus Abdomins, external obliques, internal oblique, & transverse abdominis
- - - - Air enters nose through external nares
      - Nasal cavity divided by nasal septum
    - - Olfactory receptors located in mucosa on superior air
      - Rest lined with respiratory mucosa
      - Lateral walls have conchae
    - - Cavities within bones
      - Frontal, sphenoid ethmoid, maxillary bone
      - Resonance chambers for speech
      - Produce muucus
    - - Muscular passage from nasal cavity to larynx
      - Oropharynx & laryngopharynx are common passageways for air & food
  - - - Connects larynx with bronchi
      - Fairly rigid because of the C-shaped rings made of hyaline cartilage to keep airway open at all time
    - - Formed by division of trachea
      - Enters the lung at hills
    - - Occupy most of thoracic cavity
      - Apex is near clavicle (Superior portion)
      - Base rests n diaphragm (Inferior portion)
      - Each lung is divided into lobes ( 2 on left, 3 on right)
