The Respiratory System Study Set
Terms in this set (64)
We require a continuous supply of _______.
As cells use oxygen, they give off _____ _____.
The ___________ system is to supply the body with oxygen and dispose of carbon dioxide.
To accomplish the function of the respiratory system at least four processes must happened called ___________.
What are the four processes of respiration?
- pulmonary ventilation
- external respiration
- transport of respiratory gases
- internal respiration
____________ _______ consists of inspiration and expiration.
__________ moves air into the lungs from the atmosphere.
__________ moves air out of the lungs into the atmosphere.
_________ ______ oxygen defuses from the lungs to the blood. carbon dioxide diffuses from the blood to the lungs.
the actual use of oxygen and production of carbon dioxide by tissue cells is known as __________ __________.
internal (cellular) respiration
The respiratory system is ansi involved with the sense of _____ and __________.
smell and speech
The respiratory system consists of
nose, paranasal sinuses, pharynx, larynx, trachea, bronchi, lungs, alveoli
The upper respiratory system consists of all the structures from the __________ to the __________.
The lower respiratory consists of the __________ and all of the structures __________ it.
The upper respiratory system __________, __________, and __________ air.
warms, humidifies, filters
The __________ provides an airway for respiration, moistens and warms entering air, filters and cleans inspired air, serves as a resonating chamber for speech, houses the olfactory (smell) receptors.
The structures of the nose are divided into the __________ nose and the __________ nasal cavity.
The nasal cavity is divided by a midline __________ __________ formed anteriorly by the septal cartilage and posteriorly by the vomer bone and perpendicular plate of the ethos bone,
The nasal cavity is continuous posteriorly with the nasal portion of the pharynx through the __________ __________ __________ also called the chonanae.
posterior nasal apertures
Anteriorly where the plate is supported by the palatine bones, and processes of the maxillary bones, it is called the __________ __________.
The hairs, or __________ filter coarse particles (dust, pollen) from inspired air.
The small patch of olfactory mucosa lines the slitlike superior region of the nasal cavity and contains smell receptors in its __________ __________.
The __________ __________ lines most of the nasal cavity, is a pseudostratified ciliated columnar epithelium containing giblet cells.
Seromucous nasal glands secrete about a quart of mucus containing __________.
The __________ conchae greatly increase the mucosal surface area exposed to air and enhance air tuberance in the cavity.
The conchae and nasal mucosa not only function during __________ to filter, heat, and moisten the air, but also act during __________ to relain this heat and moisture.
__________ is inflammation of the nasal mucosa accompanied by excessive mucus production, nasal congestion, and postnasal drip.
The funnel-shaped ___________ connects the nasal cavity and mouth superiorly to the larynx and esophagus inferiorly. commonly called throat.
From superior to inferior, the three regions of the pharynx are the ________, __________, __________.
nasopharynx, oropharynx, and laryngopharynx
Because the __________ lies above where food enters the body it saves only as an air passageway.
The nasopharynx is __________ __________ __________.
pseudostratified ciliated epithelium
__________ __________ traps and destroys pathogens entering the nasopharynx in the air.
The __________ contains pharyngeal tonsil, tubal tonsil, opening of pharyngotympanic tube.
The __________ contains palatine tonsil and isthmus of the fauces.
The __________ contains the esophagus and trachea.
The __________ __________ which drain the middle ear cavities and allow middle ear pressure to equalize with atmospheric pressure.
pharyngotumpanic (auditory) tubes
The __________ is a passageway for food and air is lined with a stratified squamous epithelium.
The respiratory system as a whole consist of the __________ zone and __________ zone.
respiratory and conducting
The __________ zone actual site of gas exchange, is composed of the respiratory bronchioles, alveolar ducts, and alveoli, all microscopic structures.
The __________ zone consists of all of the respiratory passageways from the nose to the respiratory bronchioles.
the __________ , voice box, provides a patent (open) airway, acts asa switching mechanism to route air and food into the proper channels, voice production (because it houses the vocal folds (vocal cords)
The large, shield shape __________ __________ is formed by the fusion of two cartilage plates at the midline.
The __________ __________ is the Adam's apple
the ring shaped __________ cartilage is perched atop and anchored to the trachea inferiorly.
__________ is the ninth cartilage, spoon shaped, is composed of elastic cartilage and is almost entirely covered by a taste bud containing mucosa.
Anything other than air entering the larynx initiates the __________ reflex.
the __________ __________ vibrate, producing sounds as air rushes from the lungs.
The __________ vocal cords play no direct part in sound production but help to close the glottis when we swallow.
stratified squamous epithelium lines the superior portion of the __________. Below the__________ __________ the epithelium is a pseudostratified ciliated columnar type that filters dust.
larynx, vocal folds
The vocal folds do not move at all when we __________, but they vibrate vigorously when we __________.
inflammation of the vocal folds, causes the vocal folds to swell, interfering with their vibration, causing hoarseness, most often caused by viral infections, but may also be due to overusing the voice, very dry air, bacterial infections, tumors on the vocal folds, or inhalation of irritating chemicals
windpipe, C SHAPED
Layers of the tracheal wall
mucosa, submucosa, hyaline cartilage, adventitia
__________ has the same goblet cell containing pseudostratified epithelium that occurs throughout most of the respiratory tract.
__________ inhibits and ultimately destroys cilia.
__________ is a connective tissue layer deep to the mucosa
contraction of the trachealis __________ the trachea's diameter, causing expired air to rush upward from the lungs with greater force.
__________ projects posteriorly from its inner face, making the point where the trachea branches into the two main bronchi
The __________ __________ is a procedure in which air in the victims lungs is used to "pop" or expel an obstructing piece of food
The air passageways In the lungs branch again, about 23 times overall, in a pattern often called the __________ __________.
The trachea divides to form the __________ and __________ bronchi
the __________ main bronchus is wider shorter, and vertical than the left
The order of the lungs
