Flashcards in Respiratory System Deck (104):
1

The exchange of gases (oxygen and CO2) at the lung capillaries (external respiration) and at the tissue capillaries (internal respiration). The mechanical process of breathing.

Respiration

2

Opening through the nose carrying air into the nasal cavity

Nares

3

Thin hairs that line the nasal cavity passageways and tubes of the respiratory tract to filter out foreign bodies and warm and moisten the air

Cilia

4

Hollow, air-containing spaces within the skull that communicate with the nasal cavity. They have a mucous membrane lining and produce mucus, lighten the bones of the skull, and help produce sound

Paranasal Sinuses

5

Throat

Pharynx

6

What are the three divisions of the pharynx?

1. Nasopharynx
2. Oropharynx
3. Laryngopharynx

7

What are found in the nasopharynx?

Pharyngeal tonsils (adenoids)

8

The exchange of air between the lungs and the outside environment

External respiration

9

What are adenoids?

Small masses of lymphatic tissue in the throat (nasopharynx); aka pharyngeal tonsils

10

Two rounded masses of lymphatic tissue in the oropharynx

Palantine Tonsils

11

Referring to the roof of the mouth

Palantine

12

Exchange of gasses between individual body cells and the capillaries that surround them

Internal Respiration

13

Serves as a common passageway for food from the mouth and air from the nose. Has two divisions

Laryngopharynx

14

What are the two divisions of the laryngopharynx

Larynx and the esophagus

15

What is the larynx?

Voice box

16

Tube that leads to the stomach and carries food to be digested

Esophagus

17

A flap of cartilage attached to the root of the tongue that covers the larynx and prevents choking or aspiration of food by blocking entry to the larynx and trachea during swallowing

Epiglottis

18

Windpipe; tube leading from the larynx (voice box) to the bronchial tubes

Trachea

19

Region between the lungs in the chest cavity. it contains the trachea, heart, lymph nodes, aorta, esophagus, and bronchial tubes

Bronchi

21

smallest brnches of the bronchi

bronchioles

22

Alveoli

23

Erythrocytes

24

Double-layered membrane surrounding each lung

Pleura

25

What are the two layers of the Pleura?

1. Parietal Pleura
2. Visceral Pleura

26

What are the differences btw the lungs?

The right lung is slightly larger and has three lobes while the left has two

27

Uppermost part of the lung

Apex

28

Lower portion of the lung

Base

29

The midline region of the lung in which blood vessels, nerves, lymphatic tissue, and bronchial tubes enter and exit

Hilum

30

Muscular partition separating the thoracic from the abdominal cavity. Contracts to pull air in the lungs and relaxes to push air out

Diaphragm

31

Pathway of air from the nose to the capillaries of the lungs

Nose (nares) - Nasal cavity and paranasal sinuses - Pharynx - Larynx - Trachea - Bronchi - Bronchioles - Alveoli - Lung Cappilaries

32

Gas produced by the body when oxygen and carbon atoms from food combine

Carbon Dioxide

33

Slit-like opening to the larynx

Glottis

34

Gas that makes up 21% of the air

Oxygen

Space between the folds of the pleura
