Speech Science #3 Exam

Front 1

Boyles Law

Back 1

As Volume increases-Pressure decreases.

As Volume decreases-Pressure increases.

Front 2

Pleural Membranes

Back 2

Viscera Pleura, Parietal Pleura, Pleural space.

Front 3

Visceral pleura

Back 3

Attatched to the lungs. Each lung covered on the outside by a thin sheet of membrane.

Front 4

Parietal pleura

Back 4

Attatched to the ribs. The Inner surface of the thorax that is lined with another layer of membrane

Front 5

Pleural space

Back 5

Between the visceral and parietal pleura, which contains pleural fluid. Pressure inside the space is Intrapleural pressure. Sucks the two membranes together, making lungs attached to the ribs.

Front 6

Bronchial Tree

Back 6

a branching system of hollow tubes that conduct air to and from the lungs.

Front 7

Trachea

Back 7

The trunk of the bronchial tree. Directly beneath the larynx, made up of 16-20 rings of cartilage, which are closed in the front and open in the back.

Front 8

Primary or Mainstem bronchi/bronchus

Back 8

The trachea splits into two branches called the primary bronchi. The right bronchus enters the right lung and the left bronchus enters the left lung.

Front 9

Secondary Bronchi/Bronchus

Back 9

Each primary bronchus divides into secondary bronchi, which supply the lobes of the lung.

Front 10

Tertiary or Segmental Bronchi/Bronchus

Back 10

Each secondary bronchus subdivides into tertiary bronchi, which go into the small segments of the lungs. They keep dividing eventually into tiny bronchioles.

Front 11

Cilia

Back 11

Millions of tiny hairlike projections in the Epithelium.

Front 12

Epithelium

Back 12

On the inside surface, the trachea is lined with a layer of ciliated pseudostratified columnar epithelium. The Epithelium contains mucous-producing cells and millions of cilia.

Front 13

Bronchioles

Back 13

What tertiary bronchi divides into. At this point, all cartilage is lost and they are composed of only smooth muscle and membrane.

Front 14

Terminal Bronchioles

Back 14

Subdivison of the Tertiary bronchi

Front 15

Respiratory Bronchioles

Back 15

Last subdivison of the Tertiary bronchi. Open up into alveolar ducts.

Front 16

Alveolar Ducts

Back 16

Opening of the respiratory bronchioles leading into an Alveolus.

Front 17

Mediastinum

Back 17

In the thoracic cavity, the space in between the lungs containing heart, blood vessels, and esophagus.

Front 18

Rib movement

Back 18

Increases thoracic space

Front 19

Surfactant

Back 19

substance in alveoli that keeps them inflated by lowering the surface tension of their walls, thus preventing them from being pulled inward during inspiration.

Front 20

Alveoli

Back 20

tiny balloon-like clusters that inflate and deflate during breathing within the lungs.

Front 21

If ribs move up and out

Back 21

Lungs move up and out

Front 22

Valves of vocal cords

Back 22

Vellum, tongue, lips. Controls air pressures

Front 23

Ribs are connected to the sternum by

Back 23

Cartilage

Front 24

Ventilation is the process of

Back 24

moving air into and out of the airways and lungs in order to exchange oxygen entering the lungs and carbon dioxide leaving the lungs.

Front 25

Pulmonary Apparatus

Back 25

Made up of the Trachea, Bronchi, Bronchioles, Alveoli, and Lungs.

Front 26

Ribs 1-7 are

Back 26

True ribs

Front 27

Ribs 8,9,10 are

Back 27

False ribs

Front 28

Ribs 11 and 12 are

Back 28

Floating ribs
