Respiratory System

air leaves trachea and enters

• main brachii

• alveoli

• pharynx

• mouth

removal of larynx results in

• loss of breath

• loss of speech

• loss of co2 exchange

• loss of cellular respiration

which does not affect lung volume

• weather

• weight

• height

• gender

trap incoming bacteria and foreign debris in nose and mouth

• alveoli

• bronchii

• mucous

• lymph nodes

flap that keeps food and drink from entering trachea

• larynx

• alveoli

• bronchii

• epiglottis

Protects surface of alveoli from collapsing, dehydration and variations in environment

• pleura

• surfactant

• alveoli

• mucous

Superior portion of the pharynx

• oropharynx

• nasopharynx

• palapharynx

• tracheapharynx

mechanoreceptors

• slow down breath

• quick increase in breath rate

• maintain breath rate

Not true of alveoli

• increase surface area

• gas exchange

• works with capallaries

• decrease surface area

not part of respiratory zone

• alveolar ducts

• bronchioles

• bronchii

• alveoli
