What controls the respiratory system?

The Brain ( medulla oblongata)

1

This forms the false vocal cords

Vestibular Folds

2

Mouth, nasal cavity, and oral cavity

Upper Airway

3

Larynx, trachea, bronchi, bronchioles and alveoli

Lower Air Way

4

Lateral walls of the nasopharynx contain three bony ridges

Conchae

5

How many lobes are in the right lung.

Sits higher, larger bronchi tube

3 upper, Middle, and lower

6

Left lung has how many lobs and what is the tiny one called?

2 / Lingula

7

Medication that is designed to improve lung functions

Bronchodilator ( albuterol)

8

Constriction of the airways passages of the lungs that accompanies muscle spasms

Bronchospasm

9

Ducts formed from divisions of the respiratory bronchioles in the lower airway; each duct ends in clustes know as alveoli

Alveolar ducts

10

tiny sacs of lung tissue in which gas exchange takes place

Alveoli

11

The very thin membrane consisting of only one cell layer, that lies between the alveolus and capillary, through which respiratory exchange between the alveolus and the blood vessels

Alveolocapillary membrane

12

Fine subdivision of the bronchi that give rise to the alveolar ducts

Bronchioles

13

The process by which a gas dissolves in a liquid

Diffusion

14

Destruction of the walls of the alveoli, which creates resistance to expiratory airflow

Emphysema

15

external openings to the nasal cavity; also called the nostril

External Nares

16

Opening into the lower airway made up of the true vocal cords and the opening between them

Glottis

17

Posterior opening from the nasopharynx into the pharynx

Interior Nares

18

Structure that separates the nasal cavity into two parts

Nasal Septum

19

Nasal cavity, which extends from the internal nares to the uvula

Nasopharynx

20

Pleural membrane that lines the pleural cavity

Parietal Pleura

21

Membranes of connective tissue that cover the lungs and line the inner borders of the ribs

Pleura

22

The cavity formed by the inner borders of the rib cage

Pleural cavity

23

Potential space between the visceral and parietal pleura

Pleural Space

24

The volume of air remaining in the respiratory passages and lungs after a forceful expiration

Residual Volume

25

Organs and structures associated with breathing, gas exchange, and the entrance of air into the body

respiratory System

26

A device used in pulmonary function testing that measures air entering and leaving the lung over a specific period of time

Spirometer

27

The pleural membrane that covers the lungs

Visceral Pleura
