1

4 basic functions of the respiratory system

respiratory
ventilation
oxygenation (removal of carbon dioxide)
serves as buffer to maintain normal acid based balance

2

refers to the process of moving oxygen and carbon dioxide across membranes, in and out of alveoli, capillaries, and cells

respiration

3

is the form of respiration in which oxygen molecules move across a membrane from an area of high oxygen concentration to an area of low concentration

oxygenation

4

is the mechanical process by which air is moved in and out of the lungs

ventilation

5

the upper airway consists of 4 structures

nose and mouth
pharynx
nasopharynx
larynx

6

the lower airway consists of 4 structures

trachea
bronchi
bronchioles
alveoli

7

from the back of the nose or mouth the air enters the (WHAT), the common passageway for food and air

pharynx

8

air from the mouth enters through the oral portion of the pharynx or the (WHAT)?

oropharynx

9

air from the nose enters the nasel portion of pharynx known as?

nasopharynx

10

lower end the phaynx divides into two stuctures:

esophagus
trachea

11

esophagus leads to the ?

stomach

12

trachea leads to the ?

lungs

13

this houses vocaal chords and is superior to the trachea

larynx

14

"Adam's Apple" is the anterior cartliage that covers the larynx

thyroid cartilage

15

most inferior part of larynx

cricoid cartilage

16

the trachea is protected by a small leaf shaped flap, automatically covers entrance of larynx during swallowing to keep food and liquid from entering trachea and lungs

epiglottis

17

the distal portion of the trachea branches into 2 main tubes one branching off to each lung these tubes are called?

bronchi

18

each bronchus divides and subdivides into smaller ?

bronchioles

19

what r bronchioles lined with?

smooth muscle

20

at the end of the bronchioles lay (WHAT) that hosts thousands of tiny air sacs, eached enclosed with a network of capillaries

alveoli

21

pricipal organs of respiration involve

lungs

22

a thin layer of connective tissue which covers the outer surface of the lungs are called

visceral pleura

23

layer of thicker more elastic tissue which covers the internal chest wall

parietal pleura

24

between the visceral pleura and parietal pleura is the (WHAT) cavity

pleural

25

this is a powerful domed shaped muscle essential for breathing that seperates the thoracic cavity from the abdominal cavity

diaphragm

26

what is characterized by adequate respiratory rate and tidal volume?

adequate breathing

27

the number of breaths a patient takes in one minute refers to the

respiratory rate

28

this is the amount of air the patient breaths in and out with one regular breath

Tidal Volume

29

in adults what is the normal range of breaths per minute?
What is the average

8-24
12-20

30

Elderly bpm
children bpm
infant bpm

20-22
15-30
25-50
