invaders (like bacteria, viruses etc.) - CORRECT ANSWER -mucus and cilia are in the upper
airway and help to move _____________ out and prevent them from getting to the lungs
filters, moistens/humidifies, warms - CORRECT ANSWER -3 functions of the upper airway
that help prepare the air to enter the lungs
alveoli - CORRECT ANSWER -gas exchanges only occurs in what structure of the lungs
R and L main bronchus, bronchi, bronchioles - CORRECT ANSWER -3 sections of the "tree"
that air flows through to reach the alveoli
smooth muscle - CORRECT ANSWER -what type of muscle surrounds bronchioles and
bronchi helping them to constrict and dilate to control the amount of air moving in and out
vasoconstriction - CORRECT ANSWER -with asthma, mast cell degranulation causes
____________ of the smooth muscles in the air passages preventing air from going into or
out of the alveoli

and surrounded by capillaries
, capillaries - CORRECT ANSWER -the location of gas change is in what type of vessel
CO2 - CORRECT ANSWER -what comes from the heart and diffuses into the alveoli
oxygen - CORRECT ANSWER -what comes from the lungs, diffuses out of the alveoli and into
the capillaries
visceral pleura - CORRECT ANSWER -lining on the outsie of the lung is called _____
parietal pleura - CORRECT ANSWER -the wall that ones the chest is called what
the pleural space - CORRECT ANSWER -_______ lies between the parental and visceral
pleura
pleaural fluid - CORRECT ANSWER -the pleural space in the lungs has what type of fluid in it
negative - CORRECT ANSWER -pleural fluid in the lung can move along the walls of the chest
and creates _______ pressure between the visceral and parietal pleura, keeping the lung
attached to the chest wall and open at all times

resistance - CORRECT ANSWER -air moves into the lungs via the path of least _______
the bases - CORRECT ANSWER -the lungs fill up where FIRST? regardless of position
wall, expand - CORRECT ANSWER -the chest _______ is normally flat, but when we have a
barrel chest, with COPD or with infants, we have less room for the lungs to ___________
ventilation, diffusion, perfusion - CORRECT ANSWER -3 parts of pulmonary function
ventilation - CORRECT ANSWER -mechanical movement of air to and from the atmosphere to
the alveoli
minute volume - CORRECT ANSWER -what does mv stand for
• tidal volume x respiratory rate/min = minute volume - CORRECT ANSWER -equation of
minute volume
respirations - CORRECT ANSWER -in certain situations, we can't get as much air into the
lungs, but if we increase the rate of _______ we can maintain the minute volume and still
maintain the gas exchange
