and 25 (Respiratory and Digestive)
In the lower respiratory system the lamina propria (areolar layer) contains __________ __________
(such as in the _____________) - smooth muscle, bronchioles
Functions of the respiratory system: provide an extensive ______________ _______ for __________
exchange between air and blood - surface area, gas
Functions of the respiratory system: moves ____ to and from exchange surfaces in the ________. -
air, lungs
Functions of the respiratory system: protect ______________ ______________ - respiratory
sufaces
Functions of the respiratory system: produce _________ (from the larynx) - sound
Functions of the respiratory system: facilitates ________________ stimulation (aka __________ ) -
olfactory, smell
Functions of the respiratory system: ______-______ balance of the blood - acid-base
The upper respiratory system is everything above the ________ - larynx
The lower respiratory system is everything below and ______ the _______ - at, larynx
function of upper respiratory system - filters, warms, and moistens air
function of lower respiratory system - sound production, conductance of air, gas exchange
,The respiratory tract consists of the ______________ and ______________ portions - conducting,
respiratory
The respiratory system is important because the body cells needs ____________ to produce _________
and remove _____________ from the body. - oxygen, ATP, carbon dioxide
Conducting portion of respiratory system: - is the movement of air only from the nasal cavity to
terminal bronchioles
Respiratory portion of respiratory - from the respiratory bronchioles to the alveoli where gas
exchange occurs
Alveoli - air sacs in the lungs for gas exchange
respiratory mucosa lines the _________________ portion of the respiratory system - conducting
The respiratory mucosa consists of - An epithelial layer and an areolar layer
Another name for the areolar later of the respiratory mucosa - lamina propria
In the upper respiratory system the lamina propria (areolar layer) contains ______________
___________ that secrete onto the epithelial surface - mucous glands
Type of cells found in the nasal cavity and nasopharynx - psuedostratified ciliated columnar
epithelium with goblet cells
Type of cells found in the oropharynx and laryngopharynx - stratified squamous epithelium
, Why are the cells in the oropharynx and laryngopharynx stratified versus the rest of the respiratory
tract? - Protection from damage occurring during the swallowing of food and beverage
Type of cells in the lower respiratory system (excluding the smaller bronchioles and alveoli) -
Psuedostratified ciliated columnar epithelium with goblet cells to remove mucus from the lungs
Type of cells in the smaller bronchioles - cubical epithelium with scattered cilia (<----in first
bronchioles only)
Type of cells in the alveoli - simple squamous epithelium without goblet cells
Why do alveoli have very thin walls? - to keep a short diffusion distance
The respiratory defense system is a series of _______________ mechanisms that remove ___________
and ___________. - filtration, particles, pathogens
Components of the respiratory system include ________________ cells and _________ working
together to _________ the air and trap particles with a _________ surface and move the trapped debris
toward the _________ - mucous/goblet, cilia, moisten, sticky, pharynx
the process of moving trapped mucus toward the pharynx is called: - mucus/mucociliary escalator
Components of the respiratory system include alveolar _____________________ that engulf small
particles that managed to reached the _________ lungs. - macrophages, lower
inherited disease affecting the respiratory defense system mechanisms - Cystic Fibrosis
Cystic fibrosis is an autosomal recessive disease meaning there is: - 2 copies of the defective gene
(1 from each parent)
