Chapter 19 - Respiratory System Flashcards
The entire process of exchanging gases between the atmosphere and body cells is called:
respiration
movement of air in and out of the lungs is called:
ventilation
Exchange of gases between the air in the lungs and the blood is called:
external respiration
Exchange of gases between blood and body cells is called;
internal respiration
o2 use and production of co2 is called:
cellular respiration
Co2 combines with water to form:
carbonic acid
too much co2 in the body does what to the blood ph?
lowers ph, more acidic
The upper respiratory tract contains:
nose, nasal cavity, sinuses, pharynx
The lower respiratory tract includes:
larynx, trachea, bronchial tree, lungs
All parts of the respiratory system, except for the alveoli, are lined with ____ _____.
mucus membranes
Olfactory receptors are found in the:
nasal cavity
Nasal cavity has what type of epithelial tissue:
pseudo-stratified columnar
Mucus is moved along by ______ to the ______ preventing mucus from entering the lower respiratory tract:
cilia, pharynx
Sinuses are found in what bones:
frontal, sphenoid, ethmoid, maxillary
The paired cartilages in the larynx are:
arytenoid, corniculate, cuneiform cartilage
The only cartilage that is elastic is the:
epiglottic
Upper folds of larynx:
false vocal cords
The lower folds
true vocal cords
Tension of vocals cords changes:
pitch
Force of air into vocal cords is:
intensity (loudness)
Which is anterior, the esophagus or the trachea?
trachea
Trachea is made of what kind of cartilage:
hyaline
Name the parts of the bronchial tree in order:
main bronchi, lobar bronchi, segmental bronchi, intralobular bronchioles, terminal bronchioles, respiratory bronchioles, aveolar ducts, alveolar sacs, alveoli
Is there any mucus in the alveoli?
no
What epithelium are the respiratory bronchioles?
simple cuboidal
What are the soft spongy organs in the thoracic cavity?
right and left lungs
1 inspiration plus 1 expiration is:
respiratory cycle
The force that moves air into the lungs is:
atmospheric pressure
Normal atmospheric pressure is:
760 mm Hg
