Chapter 23 Homework
An application of Boyle's Law is at a constant temperature
As the pressure on a gas increases, the volume decreases
During inhalation, the thoracic cavity ___________; during exhalation, the thoracic cavity ___________.
Becomes larger; returns to its original size
The ranking from highest to lowest P(O2) in the area of the arterial ends of the tissue capillaries is
Capillaries, tissue fluid, cells
At the venous ends of the pulmonary capillaries the P(CO2) is
Equal in the capillaries and in the alveoli
Expiratory Reserve Volume + Residual Volume = _______ Capacity.
Functional Residual
At the arterial ends of the pulmonary capillaries the P(O2) is
Lower in the capillaries than in the alveoli
Place the respiratory structures below in the order that air would pass through them as it moves from the outside to the inside of the body.
Nasal Cavity Nasopharynx Oropharynx Laryngopharynx Larynx Trachea
Oxygen bound to hemoglobin is referred to as _______.
Oxyhemoglobin
Boyle's Law states that
P1V1 = P2V2
If P1 and V1 represent the initial conditions, and P2 and V2 represent the changed conditions for pressure and volume, Boyle's law would state
P1V1 = P2V2
Which of the following structures is not part of the respiratory zone?
Terminal bronchioles
Pulmonary ventilation (breathing) can also be described as
The movement of air into and out of the lungs
Boyle's Law states that at a constant temperature
The pressure exerted by a gas varies inversely with the volume of that gas
As the lungs expand while breathing, the pressure in the lungs decreases.
True
As the volume in the alveoli increases, the pressure decreases.
True
During inspiration, thoracic cavity volume increases.
True
Gases diffuse because of differences in partial pressures from areas of higher pressure to areas of lower pressure.
True
