Respritory System Flashcards
.what is ventilation?
, Movement of air out in and of lungs
’ What monitors co2 and pH in the blood
Medulla oblongata and pons in brain stem
What reduces surface tension
Surfactant
Emphysema
Deconstruction of elastic tissue
What stimulates inhalation
Acidic blood
Where is pluera
In the plural cavity
What is pleura
Protective double membrane in lobes of lungs
Where does gas exchange happen
Alveoli
What is in upper respiratory system
Nose nasal cavity paranasal cavity oral cavity pharynx glottis larynx
What does lower respiratory system include
Trachea lungs bronchus alveoli
What is aerting lungs
Ventilation
Where is alveoli
Lower part of lungs where gas is exchanged
What’s produced in the larynx
Sound
What is the larynx also called
Voice box
Where does glottis lead
Larynx
What does epiglottis do
Prevent food from entering lungs
What is the flap that covers the glottis
Epiglottis
What is the pharynx opening for
Digestive system
What does the pharynx share
Air and food passageways
What are alveoli surrounded by
Capillaries
Where is the pharynx
Back of throat ending at glottis
Where does air flow from nasal and oral cavity go next
Pharynx
Where does the respiratory system begin
Nasal and oral cavity
What does alveoli allow for
Gases to move in and out of
What type of tissue is alveoli
Single layer epithelial
What do bronchioles divide into
Air sacs called alveoli
What are smaller bronchi called
Bronchioles
What does the trachea split into
Left and right bronchi
What is in front of the esophagus
Trachea
What is the trachea also known as
Windpipe
Where does oxygen go from larynx
Trachea
What can environmental factors cause
Allergies asthma bronchitis emphysema
Environmental factors
Air pollution mold
What does emphysema cause
Greater than normal expansion of lungs
Surfactant
Mixture made from cells in lungs
Ateleostasis
Collapse of lungs
What causes alveoli to stick together
Watery fluid
What is residual volume
Amount of gas remaining after deep breath
What is vital capacity
Amount of gas exchanged after deep breath
What is total lung capacity
Amount of gas in lungs after deep breath
What is tidal volume
Amount of air that enters lungs during breath
What makes blood more acidic
Increased co2 and h+ ions
Functions
‘.gas exchange, protection, regulation of blood PH
Primarily responsible for inspiration of air into the body
Diaphragm
Maximum volume of air contained in lung by full forced inhalation?
Total lung capacity
Filters out of inhaled air
Nasal hair
Volume of air exchanged during a normal breath
Tidal volume
Responsible for exchanging of gases w/ outside environment
Respiratory
Intersection of respiratory / digestive systems
Pharynx
Produces thick mucus in lungs that can impair breathing
Cystic fibrosis
