Chapter 23 - The Respiratory System - Test Packet #2

what is the function of the structures labeled "12"?

-cause air to swirl within the respiratory passageway -improve warming of incoming air -create narrow passages -help olfaction

which structure vibrates to produce sound?

11

the adult human trachea is about __________ in diameter and contains __________ tracheal cartilages

2.5 cm ; 15-20

The following is a list of some airways. What is the order in which air passes through them? 1. secondary bronchus 2. bronchioles 3. alveolar ducts 4. primary bronchus 5. respiratory bronchiole 6. alveoli 7. terminal bronchiole

4, 1, 2, 7, 5, 3, 6

the elastic cartilage that covers the opening to the larynx during swallowing is the

epiglottis

the laryngeal cartilage not composed of hyaline cartilage is the

epiglottis

during swallowing, the

epiglottis is depressed

Tina is singing a song. At a certain point in the song she forces a large volume of air out of the glottis and at the same time increases the tension on her vocal cords. The sound that she produces is

high pitched and loud

identify the structure labeled "2."

internal nares

which of the following statements about the trachea is false? -is lined by pseudostratified ciliated columnar epithelium -is reinforced with C-shaped cartilages -contains many mucous glands -alters its diameter in response to the autonomic nervous system -is reinforced with D-shaped cartilages

is reinforced with D-shaped cartilages

the C shape of the tracheal cartilages is important because

large masses of food can pass through the esophagus during swallowing

secondary bronchi supply air to the

lobes of the lungs

tension on the vocal cords is regulated by the

movement of the arytenoid cartilages and contraction of laryngeal muscles.

identify the structure labeled "7."

oropharynx

air passing through the glottis vibrates the vocal folds and produces

phonation

what is the function of the structure labeled "8"?

prevents food from entering the larynx

the __________ branch from the trachea at the carina

primary bronchi

the interlobular septa divide the lungs into

pulmonary lobules

during a chocking episode, most foreign objects are lodged in the __________ bronchus due to its larger diameter and steeper angle

right primary

a common site to place a tracheostomy tube is through the ligament that connects the cricoid cartilage to the ________ cartilage.

thyroid

the largest cartilage of the larynx is the __________ cartilage

thyroid

the airway that connects the larynx to the bronchial tree is the...

trachea

the placement of a tube directly into the trachea to bypass the larynx is termed a

tracheostomy

a pair of ligaments covered by laryngeal epithelium that function is sound production are the

vocal folds

the paired cartilages that articulate with the superior border of the cricoid cartilage are the __________ cartilages

arytenoid

an acute infection of the throat that can lead to swelling and closure of the glottis and cause suffocation is known as

acute epiglottis

contraction of the intrinsic laryngeal muscles can

close the glottis

the ring-shaped cartilage just inferior to the thyroid cartilage is the __________ cartilage

cricoid

the thyroid cartilage is attached to the cricoid cartilage by the

cricothyroid ligament
