The upper respiratory tract includes all of the following except the:
|
trachea
|
|
|
The respiratory mucosa:
|
lines most of the air distribution tubes
|
|
|
The respiratory membrane:
|
- includes the wall of the alveoli
- includes the wall of the capillaries surrounding the alveoli |
|
|
The respiratory mucosa helps protect the respiratory system by:
|
- trapping bacteria
- moving contaminated mucus towards the pharynx - having ciliated epithelium beat in only one direction |
|
|
The partition that divides the nasal cavities is called the:
|
nasal septum
|
|
|
The paranasal sinuses:
|
- are lined with mucosa continuous with the nasal cavity
- help lighten the weight of the skull bones - acta as resonant chambers for sound |
|
|
The lacrimal sacs drain directly into the:
|
nasal cavity
|
|
|
Which of the following tubes do not enter or exit the pharynx:
|
- larynx

|
|
Which of the following structures is not in the larynx?
|
the palatine tonsils

|
|
Coryza is another name for:
|
rhinitis
|
|
|
The most important muscle(s) of inspiration is (are) the:
|
diaphragm
|
|
|
Oxygen in the lung:
|
converts hemoglobin to oxyhemoglobin
|
|
|
The amount of air moved into and out of the lung during normal, quiet breathing is called:
|
tidal volume
|
|
|
Which of the following volumes of air is not included in vital capacity?
|
residual volume
|
|
|
The inspiratory and expiratory centers are located in the:
|
medulla
|
|
|
The chemoreceptors in the carotid and aorta are sensitive to:
|
- an increase in blood carbon dioxide
- a decrease in blood oxygen - an increase in blood acidity |
|
|
Which of the following terms refers to a normal respiratory rate?
|
eupnea
|
|
|
Aspiration pneumonia can be casued by:
|
inhalation of foreign matter
|
|
|
Restrictive pulmonary disorders:
|
can be the result of scarring of lung tissue
|
|
|
A sore throat is another name for:
|
pharyngitis
|
|
|
Which of the following conditions is characterized by edema of the vocal cords?
|
laryngitis
|
|
|
The trachea:
|
- is also called the windpipe
- contains C-shaped rings of cartilage - is lined by respiratory mucosa |
|
|
The smallest of the air distribution tubes in the respiratory tract are the:
|
alveolar ducts
|
|
|
The function of the surfactant in the lung is to help:
|
reduce the surface tension of water in the alveoli
|
|
|
A condition resulting from an absence or impairment of the surfactant in the alveoli is called:
|
respiratory distress syndrome
|
|
|
A collapse of the lung is called:
|
atelectasis
|
|
|
The exchange of oxygen and carbon dioxide between the blood and cells throughout the body is called:
|
internal respiration
|
|
|
During inspiration the:
|
chest cavity expands
|
|
|
During expiration the:
|
- diaphragm relaxes and moves up into the thoracic cavity
- chest cavity is reduced in volume - pressure in the thoracic cavity increases |
