Provide oxygen for metabolism
Removal of Co2
Upper Respiratory tract organs are?
Nose, pharynx, larynx, trachea
upper respiratory organ functions?
-facilitate sense of smell
-production of speech
-maintains acid-base balance
-maintains body water level
-maintains heat balance
2 nares separated by Septum
hairs trap dust and particles
lined with mucous membranes which is Vascular.
how is air in nose?
filtered, moistened and warmed
located in bones of skull w/c connects directly to nasal cavity via short duct
air filled cavity w/in the bone and lined with mucous membrane
-makes resonance for speech
-makes skull lighter
Types of Sinus
FRONTAL (pain w/ infection)
SPHENOID (damaged vision w/ infection)
MAXILLARY (pain in teeth " ")
ETHMOID SINUSES (air cell separated from eye cavity by thin layer of bone)
Throat; tubular, 5 inches. Passageway for air and food
3 subdivision of Pharynx
NASOPHARYNX (allows passage of air)
OROPHARYNX (transports, air, food and fluids downward)
contains vocal cords
Thyroid cartilage= Adam's Apple
leaf shape area of cartilage; protects larynx when swallowing.
tubelike 4 1/3 inches ( 11cm)
divides into right and left
connects larynx with bronchi
-C shaped wings
small, hairlike processes
called the windpipe, it is a strong cartilaginous tube that conducts air to and from the lungs.
Respiratory structure that communicates with the middle ear by the eustachian tube
adam's apple/thyroid cartilage is most associated with this structure.
the epiglottis directs food and water from the respiratory passages into this structure.
called voicebox because it contains the vocal cords.
point which trachea bifurcates (splits)
located b/t larynx and bronchi in front of esophagus
composed of three parts -naso, -oro, -laryngo
large tube that splits into bronchi
These small structures located within the broncial tree are composed primarily of smooth muscle
the exchange of respiratory gases b/t air and blood occurs here.
large, soft, cone shaped organs that contain the respiratory passages and pulmonary capillaries. fill most of the thoracic cavity.
coz of smooth muscle, this structure can contract and relax, thereby causing constriction and dilation.
the olifactory receptors are located within these cavities.
Mucus drains into the nasal cavities from these structures located in the head.
tracheas splits into the right and left
deliver o2 to the alveoli
structures partially encircled by the pulmonary capillaries.
called resistance vessels
separated by the nasal septum
space between the vocal chords
structure with largest cross sectional area; designed for gas exchange.
space between visceral and parietal pleural membranes
pressure must be negative on this area for lungs to remain expanded.
Pneumothorax occurs when air enters this area
Membrane on the outer surface of each lung
muscle separating the thoracic and abdominal cavity
chief muscle of inhalation
motor nerve that stimulates the diaphragm
area b/t two lungs. Contains thoracic structures (heart, large blood vessels, and trachea)
contains pleural cavity, pericardial cavity and mediastinum
Skeletal muscle between ribs
Neurotransmitter at the neuro muscular junction
amount of air inspired and expired during normal breathing
tissue that stops food and liquids from entering nasal cavity
occurs when o2 and coz are exchanged in lungs
serous membrane that lines thoracic cavity
1 inspiration and 1 expiration
oropharynx and laryngopharynx
parts of both digestive and respiratory system
gas exchange in lungs is done by tiny structures called
waste product produced by cells
medical name for nostrils
increased shallow breathing resulting in too much carbon dioxide
found in lungs that prevents alveoli from collapsing
slow shallow breathing
increased rate and depths of respiration
absence of respiration
