BIOS255 Week 7 Respiratory System-
Physiology – Graded An A+
The relationship between pressure and volume in a closed space is described by
✔✔Boyle's Law
which gas is the most common in the atmoshphere ✔✔Nitrogen
Which is not considered a conducting zone structure? ✔✔alveoli
In spirometry, what is the definition of tidal volume (TV)? ✔✔The volume of air inhaled
or exhaled during a normal, quiet breath.
Which lung volume represents the air that remains in the lungs after a maximal
exhalation and never leaves, maintaining lung elasticity? ✔✔Residual volume (RV)
What is a function of anatomical dead space in the respiratory system?
✔✔Humidification and filtration of inhaled air
Which calculation describes the total amount of air inhaled per minute ✔✔Minute
ventilation rate
A client has a tidal volume of 650 mL/breath, an anatomical dead space of 150 mL, and
a respiratory rate of 20 breaths/min. Calculate the client's alveolar ventilation rate
(AVR). ✔✔10 L/min
What is the primary purpose of measuring functional residual capacity (FRC) in
spirometry? ✔✔To assess the amount of air left in the lungs after a normal exhalation
What is a characteristic of restrictive lung disorders? ✔✔Decreased lung compliance
Because gas exchange does not occur within the conducting zone of the respiratory
system, it is also referred to as ✔✔anatomical dead space
A client has a tidal volume of 600 mL/breath and a respiratory rate of 15 breaths/min.
Calculate the client's minute respiratory volume (MRV). ✔✔9.0 L/min
Which are obstructive lung disorders? Select all that apply. ✔✔Chronic Bronchitis,
Asthma
, The - is the amount of air remaining in the lungs after a forced expiration. ✔✔1. residual
volume
The volume of air exchanged during normal breathing is called the ✔✔tidal volume
The amount of air that can be forcefully inhaled after a normal inspiration is called the
✔✔inspiratory reserve volume
the - is the maximum volume of air a person can exhale after a maximal inhalation.
✔✔vital capacity
What is the approximate volume of the anatomical dead space in the respiratory
system? ✔✔150 mL
Which transport mechanism do gases such as oxygen and carbon dioxide use to move
across cell membranes? ✔✔Simple diffusion
Which type of epithelium is found in the alveolar walls? ✔✔Simple squamous epithelium
Hemoglobin (Hb) can bind up to - molecule(s) of oxygen. ✔✔4
Which gas has the highest partial pressure in atmospheric air? ✔✔Nitrogen
Which gas law states that the solubility of a gas is proportional to its partial pressure?
✔✔Henry's law
What is the primary molecule responsible for transporting oxygen in the blood to
systemic tissues? ✔✔Hemoglobin
What percentage of carbon dioxide is bound to hemoglobin to form
carbaminohemoglobin? ✔✔5%
Which are forms in which carbon dioxide can be transported in the blood? Select all that
apply. ✔✔In plasma in the form of bicarbonate ions, Bound to hemoglobin
What physiological response occurs when active tissues consume oxygen rapidly,
resulting in a low partial pressure of oxygen (PO2)? ✔✔Hemoglobin releases more
oxygen.
What is the partial pressure of O2 in a room with 800 mmHg of air pressure, 25% O2,
and 1400 liters of air? ✔✔200 mmHg
What is the primary route used for transporting carbon dioxide through the blood?
✔✔Formation of carbonic acid
