Flashcards in Respiratory System Ch 7 Deck (30)
4 basic functions of the respiratory system
oxygenation (removal of carbon dioxide)
serves as buffer to maintain normal acid based balance
refers to the process of moving oxygen and carbon dioxide across membranes, in and out of alveoli, capillaries, and cells
is the form of respiration in which oxygen molecules move across a membrane from an area of high oxygen concentration to an area of low concentration
is the mechanical process by which air is moved in and out of the lungs
the upper airway consists of 4 structures
nose and mouth
the lower airway consists of 4 structures
from the back of the nose or mouth the air enters the (WHAT), the common passageway for food and air
air from the mouth enters through the oral portion of the pharynx or the (WHAT)?
air from the nose enters the nasel portion of pharynx known as?
lower end the phaynx divides into two stuctures:
esophagus leads to the ?
trachea leads to the ?
this houses vocaal chords and is superior to the trachea
"Adam's Apple" is the anterior cartliage that covers the larynx
most inferior part of larynx
the trachea is protected by a small leaf shaped flap, automatically covers entrance of larynx during swallowing to keep food and liquid from entering trachea and lungs
the distal portion of the trachea branches into 2 main tubes one branching off to each lung these tubes are called?
each bronchus divides and subdivides into smaller ?
what r bronchioles lined with?
at the end of the bronchioles lay (WHAT) that hosts thousands of tiny air sacs, eached enclosed with a network of capillaries
pricipal organs of respiration involve
a thin layer of connective tissue which covers the outer surface of the lungs are called
layer of thicker more elastic tissue which covers the internal chest wall
between the visceral pleura and parietal pleura is the (WHAT) cavity
this is a powerful domed shaped muscle essential for breathing that seperates the thoracic cavity from the abdominal cavity
what is characterized by adequate respiratory rate and tidal volume?
the number of breaths a patient takes in one minute refers to the
this is the amount of air the patient breaths in and out with one regular breath
in adults what is the normal range of breaths per minute?
What is the average
