Respiratory System
Study Guide
Question | Answer |
---|---|
What are the conducting passageways, in order, from the external nares to the alveolar bundles? | nares, nasal cavity, pharynx, larynx, trachea, bronchi, and bronchioles |
What are the functions (2) of the respiratory system? | to transport oxygen and remove extra carbon dioxide |
What are the 5 functions of the nose? | air, filter air, smell, warms and moistens air, lets are move through body |
What does the nasal cavity does to air during inspiration? | During inhalation the conchae and nasal mucosa filter, heat, and moisten air |
What does the nasal cavity does to air during expiration? | During exhalation these structures reclaim heat and moisture and minimize heat and moisture loss |
What function do the cilia on the nasal mucosa serve? | Ciliated mucosal cells remove contaminated mucus |
Which structures separate the nasal cavity from the oral cavity? | The hard and soft palate |
What are the functions of the paranasal sinuses? | Sinuses in bones that surround the nasal cavity, sinuses lighten the skull, resonate speech, and produce mucus |
What are the sections of the pharynx superior to inferior? | Nasopharynx, Oropharynx, and Laryngopharynx |
Which section of the pharynx is strictly for air? | The nasopharynx is strictly for air |
What closes during swallowing that ensures this? | The nasopharynx closes during swallowing |
Which structures produce the sounds known as speech? | The larynx (voice box) produces the sounds |
Where is the larynx found? | It is attached to the hyoid bone and opens into the laryngopharynx superior |
What function do bronchial arteries perform for the lungs? | They provide systemic blood to the lung tissue |
What composes the respiratory zone? | respiratory bronchioles, alveolar ducts, and alveoli |
What is the function of the respiratory zone? | It is the site for gas exchange |
Which type of tissue composes the walls of the alveoli? | They are a single layer of Type I epithelial cells (squamous) |
Through what process is oxygen and carbon dioxide exchanged between the alveoli and capillaries? | In a process called diffusion, oxygen moves from the alveoli to the blood through the capillaries (tiny blood vessels) lining the alveolar walls |
Cells in your lungs secrete _______________, a detergent-like complex which coats and lowers surface tension in alveoli. | surfactant |
Which respiratory response has similar air movements to laughing? | Non-respiratory movements |
What is the function of the hyaline cartilage of the trachea? | It provides support and keeps the trachea from collapsing |
