The three regions of the pharynx are the:
Nasopharynx, oropharynx, laryngopharynx
The large shield-shaped thyroid cartilage that protrudes anteriorly is commonly called the:
Adam's Apple
The mucosa-lined windpipe that extends from the larynx to the level of the fifth thoracic vertebra
Trachea
Gas exchange occurs in the
Alveoli
What is the role of mucus in the nasal cavity
Trap incoming bacteria and other foreign debris
Contaminated mucus is removed from the lower respiratory passageways, such as the trachea, by
Cilia
Following the removal of the larynx, a person would be unable to
Speak
(T/F)The nasal cavity is separated from the oral cavity by the nasal conchae.
False
(T/F)The function of the C-rings of hyaline cartilage in the trachea is to keep the airway patent or open for breathing
True
(T/F)Each main (primary) bronchus enters the lung at the apex
False; enters lung at hilum (depression on medial side of lung).
The mucosa-lined windpipe that extends from the larynx to the level of the fifth thoracic vertebra is called the
Trachea
The C-shaped rings that reinforce the trachea are constructed of ___________ cartilage
Hyaline
The flap of elastic cartilage that protects the opening of the larynx is called the
Epiglottis
Gas exchange occurs in the
Alveoli
Which tonsils is/are located in the oropharynx at the end of the soft palate
Palatine Tonsils
Air from the nasal cavity enters the superior portion of the pharynx called the
Nasopharynx
Contaminated mucus is removed from the lower respiratory passageways, such as the trachea, by
Cilia
(T/F)There are only three paranasal sinuses located in the frontal, sphenoid, and parietal bones
False; paranasal sinuses are located in frontal, sphenoid, ethmoid, and maxillary bones.
(T/F)The portion of the pharynx continuous with the mouth is termed the oropharynx
True
(T/F)Inspiration results when the diaphragm and external intercostal muscles relax
False; inspiration is when the diaphragm and external intercostal muscles contract; the above is expiration
The three mucosa-covered projections into the nasal cavity that greatly increase surface area of mucosa exposed to air are called
Conchae
Clusters of lymphatic tissue in the pharynx are referred to as
Tonsils
Folds of mucous membrane called ___________ vibrate to provide speech
Vocal folds/true vocal cords
Which one of the following bones does NOT contain paranasal sinuses:
Mandible
The respiratory movement representing the total amount of exchangeable air is the:
Vital capacity
The amount of air that can be forcibly exhaled after a tidal expiration is about
1200 mL
The amount of air exchanged during normal quiet breathing is about
500 mL
The respiratory rate in adults is
12-18 respirations per minute
(T/F)Expiration occurs when the thoracic and intrapulmonary volumes decrease and the intrapulmonary pressure increases
True
(T/F)Bronchial sounds are produced as air fills the alveoli of the lungs
False; bronchial sounds are produced by air rushing through the large respiratory passageways; the description above is called vesicular breathing sounds
Inflammation of the sinuses that can cause marked changes in voice quality is called
Sinusitis
he serous membrane that surrounds each lung is created by a parietal and visceral
Pleura
The presence of air in the intrapleural space is known as
Pneumothorax
What is the most common cause for lung cancer
Smoking
The homeostatic imbalance associated with the death of many full0term newborn infants is called
SIDS (sudden infant death syndrome)
Wwhich of these age-related disorders is related to loss of elasticity of the lungs and hypoxia:
Sleep apnea
Which one of the following is NOT true of lung cancer:
It is generally more prevalent in males than females
(T/F)The nasal cavity is separated from the oral cavity by the nasal conchae
False; the cavities are separated by the hard (maxilla) and soft (muscle tissue) palate
(T/F)The "guardian of the airways" that prevents food from entering the superior opening of the larynx is the thyroid cartilage
False; the epiglottis guards the airways; it is made of hyaline cartilage
The emergency surgical opening of the trachea is called a tracheostomy
True
