anatomy/physiology respiration #2

Pharynx

The respiratory structure that functions as a passageway for air going to the lugs and food going to the esophagus

Alveoli

microscopic air sacs in the lungs

inspiratory reserve volume

amount of air that enters the lungs during a forced inspiration beyond what is normally inhaled

expiratory reserve volume

the return of ribs and diaphragm to their normal pre-inspiration position after inhalation has occurred

residual volume

amount of air that remains in the lungs after the most forceful expiration

nasal cavity

respiratory structure that warms the incoming air and traps foreign particles

reparatory membrane

the permeable structure that separates the air sacs from the capillaries in the lungs through which oxygen and carbon dioxide pass

surfactant

substance that keeps the alveoli from sticking together and collapsing

tidal volume

the air that enters and exits the lungs during a normal respiration

dorsal respiration group

the portion of the medullary rhythmicity area responsible for the control of normal breathing pattern

epiglottis

the structure that covers the entrance, to the larynx during swallowing to keep food from entering the respiratory passages

expiratory reserve volume

the amount of air that can be expelled from the lungs during forceful expiration

pons

the portion of the brain that controls the rate of breathing

bronchi

the major air passageway leading to each lung

vital capacity

the inspiratory reserve volume, plus the tidal volume, plius the expiratory reserve volume

surface tension

the term for the force that holds the parietal pleura and the visceral pleura together during inspiration

larynx

the repertory structure that carriers air from the throat to the windpipe

ventral respiratory group

the portion of the medullary rhythmicity area that causes more forceful inspirations

total lung capacity

vital capacity plus residual volume

bronchioles

the smallest air passages leading to the air sacs

simple squamous

type of epithelium found in the respiratory membrane

trachea (windpipe)

the respiratory structure that immediately precedes the primary bronchi

secondary bronchi

air passageways branching off the major bronchi leading into each lung
