The Upper Respiratory Structures
• Nasal Cavity– Contains the superior, middle and inferior
nasal conchae
• Pharynx– Divided into three sections the nasopharynx,
oropharynx and laryngopharynx

The Lower Respiratory Structures
• Larynx– Made of cartilage and ligaments– 3 Major cartilages of the larynx:
• Thyroid cartilage• Cricoid cartilage• Epiglottis
– Contains vocal cords, which surround an opening called the glottis

Trachea
• Windpipe – brings air to/from lungs
• Contains tracheal cartilages which protect the airway and prevent collapse

Bronchiole & Alveoli
Fig. not in you lab book
Also known as a septal cell: produces SURFACTANT which reduces the surface tension in the alveoli

Slide of a Bronchiole
Bronchiole(notice it is filled with air so it is empty inside)
Alveoli or Alveolar Sacs
Simple Squamous Epithelia
Blood Vessel(notice it is filled with RBC’s)
