A&p Ch. 22 Unit Exam Review

Front 1

The upper respiratory tract contains the respiratory organs located outside the chest cavity:

Back 1

The nose and nasal cavities, pharynx, larynx, and upper trachea.

Front 2

The lower respiratory tract consists of organs located in the chest cavity:

Back 2

The lower trachea, bronchi, bronchioles, and alveoli. The pleural membranes and the muscles that form the chest cavity are also part of the lower respiratory tract.

Front 3

What is the function of alveoli?

Back 3

Are tiny sacs located at the distal end of the respiratory passages. They are concerned with the exchange of oxygen and carbon dioxide, the respiratory gases, between the air and the blood across the walls of the pulmonary capillaries.

Front 4

Pharynx

Back 4

Or throat is located behind the oral cavity and between the nasal cavities and the larynx.

Front 5

Pharynx includes three parts:

Back 5

The nasopharyngeal (upper section), the oropharynx (middle section) and the laryngopharynx (lower section)

Front 6

Pharynx includes three parts:

Back 6

The nasopharyngeal (upper section), the oropharynx (middle section) and the laryngopharynx (lower section)

Front 7

The larynx is also called the

Back 7

Voicebox, is located between the pharynx and trachea.

Front 8

The larynx has three functions:

Back 8

It acts as a passageway for air during breathing, it produces sound (your voice), and it prevents food and foreign objects from entering the distal respiratory structures.

Front 9

Epiglottis

Back 9

Acts as a flap, a very important flap. It covers the opening of the trachea during swallowing so that food does not enter the lungs.

Front 10

The larynx is called the voicebox because it contains the vocal cords.

Back 10

The vocal cords are folds of tissue composed of muscle and elastic ligaments and covered by mucous membrane.

Front 11

The larynx is called the voicebox because it contains the vocal cords.

Back 11

The vocal cords are folds of tissue composed of muscle and elastic ligaments and covered by mucous membrane.

Front 12

The glottis is:

Back 12

The space between the vocal cords.

Front 13

The larynx is called the voicebox because it contains the vocal cords.

Back 13

The vocal cords are folds of tissue composed of muscle and elastic ligaments and covered by mucous membrane.

Front 14

The glottis is:

Back 14

The space between the vocal cords.

Front 15

There are two types of vocal cords; false and true vocal cords.

Back 15

False: do not produce sounds. Instead the muscles in the in this structure help to close the airway during swallowing. True vocal cords produce sound. Airway from the lungs through the glottis during exhalation causes the true vocal cords to vibrate, thereby producing sound.
