Exam 23 Flashcards
Boyle’s Law says that increased volume results in:
Decreased pressure
What makes up the respiratory epithelium.
- Cilia
- Goblet cells
- Pseudostratified columnar epithelium
What is the correct formula for MV
RV x TV=MV
What is the correct formula for the Total Lung Capacity
IRV + TV + ERV + RV = Total Lung Capacity
What describes the trachea
- Cilia
- C-Shaped rings of cartilage
- Goblet cells
Choose all that might apply for an infant born prematurely
- An underproduction of surfactant
- An inability to inflate the lungs
Choose the unpaired cartilages. May be more than one right answer.
Thyroid, cricoid, and epiglottis
Contraction of the external intercostal muscles moves the ribs upward and outward, causing the rib cage to expand, which increase the thoracic cavity. Because of this:
Intrapulmonary pressure will decrease
If pathogens or debris make it past the mucous membranes, nasal hair, cilia, and all the other mechanisms meant to trap it, the ________ will attempt to engulf and remove it.
Alveolar macrophage
Ingrid is relaxed and practicing yoga. She is concentration on quiet, relaxed breathing. This breathing pattern is referred to as:
Eupnea
John broke his ribs in a car accident. It is very painful to breathe, and consequently, he has
Decreased thoracic wall compliance
Sympathetic nervous stimulation results in:
Bronchodilation
Starting from the outside, trace a molecule of O2 to the alveolus.
- Nares
- Pharnyx
- Larynx
- Trachea
- Bronchi
- Terminal bronchioles
- Alveoil
The Bohr effect is that lowering the blood pH will cause:
Hemoglobin will be saturated at a lower pO2, therefore releasing more oxygen
The SECOND most important muscle in creating mechanical ventilation is the:
External intercostals
The _________ is shared by the digestive and respiratory systems.
Pharynx
The bones that create turbulence as well as adding warmth and humidity to inhaled air are the ______________ bones.
Conchae
The flexible piece of elastic cartilage that folds to block food from entering the trachea is the _____________.
Epiglottis
The immunoglobulin found of the respiratory mucosal membranes:
IgA
The serous membrane that attached to the surface of the lungs is the:
Visceral pleura
The sum of the TV + TRV + ERV is the:
Vital capacity
The type II alveolar cell secretes __________.
Surfactant
Which structure contains that highest proportion of cartilage:
Trachea
Another word for a collapsed lung:

The respiratory epithelium of the conducting airways consists of
Pseudostratified ciliated columnar epithelium
The term hypercapnia refers to
Elevated PCO2-
The Hering-Breuer reflex
Protects the lungs from damage due to overinflation
The glottis is
The opening to the larynx
The vocal folds are located within the
Larynx
The actual sites of gas exchange within the lungs are
Alveoli
When the diaphragm and external intercostal muscles contract
the volume of the thorax increases
If a patient being tested inhales as deeply as possible and then exhales as much as possible, the volume of air expelled would be the patient’s
Vital capcity
________________ is the amount of air that you can inhale above the resting tidal volume.
Inspiratory reserve volume
Most of the oxygen transported by the blood is
Bound to hemoglobin
The most important chemical regulator of respiration is
Carbon dioxide
