Physiology Week 12: Respiratory and Gas Exchange

QuestionAnswer
Which oxygen-binding protein helps move oxygen out of the blood and into muscle cells? myoglobin
The apparatus used to measure the volume of air exchanged in breathing is called a(n) spirometer
True or False: The mechanism that produces pulmonary ventilation is one that establishes a gas pressure gradient between the atmosphere and the alveolar air. True
______ law states that the volume of a gas is inversely proportional to its pressure. Boyle's
An obstructive lung disorder that is characterized by recurring spasms of the smooth muscles in the wall of the bronchial air passages is asthma
The volume of air exhaled normally after a typical inspiration is called _____ volume. tidal
The exact amount of oxygen in blood depends mainly on the amount of? hemoglobin
A type of breathing characterized by gradually increasing tidal volume for several breaths followed by several breaths with gradually decreasing tidal volume is: Cheyne's-Stoke respiration
When the pressure in the lung is greater than atmospheric pressure: inspiration occurs or expiration occurs? expiration occurs
During inspiration, the expansion of the lungs causes: an INCREASE or DECREASE in alveolar pressure? decrease
