Alveolus slide
a small cavity, pit, or hollow, in particular.
any of the many tiny air sacs in the lungs where the exchange of oxygen and carbon dioxide takes place
simple squamous epithelium slide
blood vessel slide
bronchiole slide
Cilia slide
Hyaline cartilage slide
smooth muscle slide
adipose tissue slide
Hard palate function
The hard palate is important for feeding and speech
soft palate function
It is responsible for closing off the nasal passages during the act of swallowing, and also for closing off the airway. During sneezing, it protects the nasal passage by diverting a portion of the excreted substance to the mouth.
glottis function
As the vocal folds vibrate, the resulting vibration produces a "buzzing" quality to the speech, called voice or voicing or pronunciation
epiglottis function
prevents food from going into the trachea and instead directs it to the esophagus
ELASTIC CARTILAGE
trachea function
air-conducting tube (commonly known as your windpipe)
esophagus function
to carry food, liquids, and saliva from the mouth to the stomach.
bronchi function
The bronchi, singularly known as a bronchus, are extensions of the windpipe that shuttle air to and from the lungs. Think of them as highways for gas exchange, with oxygen going to the lungs and carbon dioxide leaving the lungs through them.
thyroid cartilage function
It plays a role in the production of the human voice, providing protection and support for the vocal folds.
visceral pleura function
cover the lungs
parietal pleura function
line the thoracic cavity
diaphragm function
The diaphragm is the main muscle of respiration. Contraction of the diaphragm muscle expands the lungs during inspiration when one is breathing air in.
lobes of lung function
The respiratory system's alveoli are the sites of gas exchange with blood.
ventilation
ventilation is the movement of air between the environment and the lungs via inhalation and exhalation
inspiration
the drawing in of breath; inhalation
expiration
exhalation of breath
tidal volume
Tidal volume is the lung volume representing the normal volume of air displaced between normal inhalation and exhalation when extra effort is not applied
expiratory reserve volume
the additional amount of air that can be expired from the lungs by determined effort after normal expiration
inspiratory reserve volume
The maximal volume of air that can be inhaled after a normal inspiration. Also called complemental air.
minute respiratory volume
is the volume of gas inhaled (inhaled minute volume) or exhaled (exhaled minute volume) from a person's lungs per minute.
residual volume
is a lung volume representing the amount of air left in the lungs after a forced exhalation; this volume cannot be measured, only calculated.
nasal conchae
increase the surface area of the nasal cavity
nares
nostrils
vestibule
space internal to lips and cheeks and external to the gums and teeth
hyoid bone
bone for attachment for muscles of the tongue and larynx
epiglottis
flap that covers the opening into the larynx during swallowing
thyroid cartilage
shield like part of the larynx; Adam's apple
vocal folds
inward extensions of mucous membranes in the larynx; responsible for speech
cricoid cartilage
base of larynx
arytenoid cartilage
serve as anchors for laryngeal muscles
pharyngeal tonsils (adenoids)
lymphatic tissue
eustachian tube
equalization in air pressure between the atmosphere and middle ear
uvula
helps close off the nasopharynx during swallowing
glottis
opening to the larynx
alveoli
capillary network
left inferior lobe
primary bronchi
what four bones make up the hard palate
2 maxilla and 2 palantine bones
the tonsils are parts of which organ system
lymphatic/immune
of what possible significance are the tonsils and adenoids to respiratory functioning
traps pathogens before they get further into the lower respiratory structures
name two serous membranes other than pleura
pericardium and peritoneum
is the apex of the lung at the inferior or the superior border
superior
bronchi are called bronchioles as they approach what diameter
1mm
which vessels carry oxygenated blood- pulmonary arterioles or pulmonary venules
pulmonary venules
type of tissue that lines the inside of blood vessels
simple squamous epithelium (called endothelium)
type of tissue that lines the inside of most air passageways
pseudostratified ciliated columnar epithelium
vital capacity
max. you can breathe in and then blow out
expiratory reserve volume
amount you can breathe out beyond quiet exhalation
hypoventilation
breathing at an abnormally slow rate, resulting in an increased amount of carbon dioxide in the blood.
hyperventilation
breathing too fast and deep
