I - respiratory: pulmonary ventilation : movement of air in and out of lungs. External respiration : exchange of oz and coz between lungs and blood. Internal respiration ! exchange of oz and coz between systemic blood vessels and tissues. Pharynx : runs from base of skull to cg vertebrae: nose and nasal cavity, paro nasal sinus, pharynx. =- lower respiratory: larynx, trachea connects nasal cavity } mouth to larynx } esophagus funnel shaped skeletal muscle tube , you have control1. Nasopharynx : pseudostratified columnar epithelium soft palate , uvula , tonsils , phoryngotympanic tube oropharynx ! stratified squamous epithelium. D opening to oral cavity , isthmus of fauces tonsils a: bronchi and branches larynyopharynx : stratified squamous epithelium, lungs and alveoli. Nose is the only external portion of respiratory system or houses olfactory receptor. Nasal cavity moistens and warms entering air filters and cleans air resonating chamber for speech. Posterior nasal aperture : opening of nasal cavity.
