The system is made up of
Blood vessels
Lungs
The nasal cavities
Pharynx
Larynx
Tonsils
Trachea
Bronchi
Broncioles
Alveoli
Roles of the respiratory system
Supplying oxygen to the internal environment
Eliminating CO2 from the internal environment
Inspiration is when the pressure of oxygen is higher in the lungs than in the atmosphere
Expiration is when the pressure of CO2 is greater that the atmosphere
Inspiration is when the pressure of oxygen is lesser than the atmospere
Conducting portion of RS
Transport of gases
Cleaning air
Moisturizing air
Heating air
Includes the alveolar ducts
Includes the respiratory bronchioles
Includes the nasal cavity, pharynx and larynx
Includes the trachea, bronchi and bronchioles
Respiratory portion of RS
Transports gases to the lungs
Performs the gas excange between lungs and blood
Gas exchange happens between lumen of capillaries and alveolis
Includes alveolar ducts
Alveolar sacs
Trachea, bronchi and bronchioles
Nasal cavity
Vestibules are lined with stratified squamous epithelium
The internal nasal cavity is lined by olfactory epithelium
The olfactory segment is lined by olfactory epithelium
The internal nasal cavity is lined by respiratory epithelium
Vestibule

Sweat glands
Is keratinized in its inferior part
Is non-keratinized in its inferior part; respiratory epithelium
Does not contain a mucous layer
Contains thick, short hairs; cilium
Nasal fossae
Lies in mucosa
A-vascular
Contains swell bodies
Reacts in allergic reactions by swelling
Plays a part in heating air
The mechanical heat exchange system
Does not play a part in epithelium recovery
Paranasal sinuses
Are extentions of the nasal cavities
Found in bones of the skull
Cannot communicate with the nasal cavities
Rarely gets infected by viruses
Olfactory segment
Has chemoreseptors
Chemoreseptors plays a part in ability to taste
Chemoreseptors plays a part in ability to smell
Contains supporting cells
Basal cells
Olfactory cells
Basal cells are stemcells, renewing olfactory cells
Olfactory cells gives mechanicaql and physiological support
Pharynx
Connects the nasal and oral cavity
Nasopharynx
Oropharynx
Laryngopharynx
Nasopharynx is covered by stratified squamous epithelium
Nasopharynx is covered by respiratory epithelium
Oropharynx is covered by stratified squamous epithelium
Larynx
Connects the pharynx to the nasal cavity
Connects the pharynx to the trachea
Contains irregular shaped cartilage in its lamina propria
Phonation organ
"False vocal cords" are composed of vestibular cords
"True vocal cords" are composed of respiratory epithelium
"True vocal cords" are composed of stratified squamous epithelium
The composition of the tissue helps with protection from abration and desiccation from rapid air movement
Vocal ligaments has reticular fibers
Vocal ligament has elastic fibers
Vocalis muscle
Plays a part in controlling air flow
Plays a part in producing sound
Respiratory epithelium
Pseudostratified ciliated columnar epithelium
Stratified squamous epithelium
Has ciliated cells
Goblet cells
Reseptor cells
Exocrine granules
Endocrine granules
Basal stem cells
Axons
Dendritic cells
Lympocytes
Trachea
Two layers; mucosa and adventitia
Three layers; mucosa, submucosa and adventitia
Made of stratified squamous epithelium
Composed of respiratory epithelium
Rich in elastic fibers
Mucosa has seromucous glands
Mucosa has seromucous glands
Has hyaline cartilage
Trachealis muscle

Smooth muscle arranged in spirals
Bronchioles
Lined with simple squamous epithelium
Lined with ciliated simple columnar epithelium
Lined with ciliated simple cuboidal epithelium
Smooth muscle cells are present
Reticular fibers; circumferential layer

Respiratory bronchiole
Allows gas exchange
Alveoli
Alveoli are found on the surface of bronchioles
Alveoli are extentions from the lumen of bronchiole
Alvioli
Site of gas exchange
Seperated by a interalveolar septa
Type I pneumocyte: squamous, included in blood-air barries
Type II pneumocyte: Cuboidal septal cells; lowers surface tension
