Respiratory System Practical Nursing

Front 1

The order in which oxygen passes from the environment through the respiratory system is

Back 1

Nasal cavities, pharynx, larynx, trachea, lungs

Front 2

What substance reduces surface tension and prevents the alveoli from collapsing?

Back 2

Surfactant

Front 3

The respiratory membrane serves an important function. It:

Back 3

Separates the air in the alveoli from the blood in surrounding capillaries

Front 4

True or False:The respiratory mucosa is composed of pseudostratified ciliated epithelium

Back 4

True

Front 5

What is the respiratory tract composed of?

Back 5

Ciliated mucous membrane

Front 6

What is included in the conducting system of the respiratory system?

Back 6

Nose, pharynx, larynx, trachea, bronchii, bronchiole and terminal bronchioles

Front 7

What is included in the respiratory portion of the respiratory system?

Back 7

Respiratory bronchioles, alveolar ducts, alveolar sacs, alveoli

Front 8

What is another term for inhalation?

Back 8

Inspiration

Front 9

What is another term for exhalation?

Back 9

Expiration

Front 10

Explain how inhalation occurs?

Back 10

Occurs when air moves from the atmosphere of high pressure into the lower pressure of the lungs (lung volume increases and pressure in lungs decreases)

Front 11

Explain how exhalation occurs

Back 11

Occurs when air rushes down the pressure gradient and outside the body (volume decreases and pressure in lungs increases)

Front 12

How does exhalation occur?

Back 12

When the diaphragm pushes against the lungs, which causes air pressure in the lungs to increase so that it is higher than the air pressure in the atmosphere

Front 13

What is tidal volume?

Back 13

The amount of air involved in one normal inhalation and exhalation

Front 14

What does IRV stand for?

Back 14

Inspiration Reserve Volume

Front 15

What is IRV?

Back 15

Inhale a normal volume of air, now inhale even more

Front 16

What does ERV stand for?

Back 16

Expiratory Reserve Volume

Front 17

What is ERV?

Back 17

Exhale a normal amount of air, now exhale as much as you can.

Front 18

What is residual volume?

Back 18

The amount of air that remains in the lungs after a forceful exhalation

Front 19

Describe the exchange of oxygen and carbon dioxide during external respiration?

Back 19

Exchange of gases between the air in the alveoli and the capillary blood in the lungs

Front 20

Describe the exchange of oxygen and carbon dioxide during internal respiration?

Back 20

Exchange of gases between the blood in the systemic capillaries and the cells of the body

Front 21

Where are central chemoreceptors located?

Back 21

In the medulla

Front 22

What do the central chemorecptors do?

Back 22

Respond to changes in hydrogen ions or carbon dioxide

Front 23

What are peripheral chemoreceptors sensitive to?

Back 23

Low concentrations of O2 and increased levels of hydrogen ions

Front 24

Describe how blood transports oxygen and CO2

Back 24

Transports them either as solutes or combined with other chemicals.

Front 25

What other compounds can oxygen and CO2 be chemically bonded with to better aid in transport?

Back 25

Hemoglobin, plasma protein, or water

Front 26

What is the primary gas transport molecule of the blood?

Back 26

Hemoglobin

Front 27

What are the alveoli coated in that prevents them from collapsing during gas exchange?

Back 27

Surfactant

Front 28

The opening of the larynx is partially covered by what?

Back 28

Epiglottis

Front 29

What are the two basic functions of the respiratory system?

Back 29

Air distribution and gas exchange

Front 30

Gas exchange occurs in the?

Back 30

Alveoli

Front 31

How many lobs in total for both lungs?

Back 31

5

Front 32

How many lobes in each lung?

Back 32

Left has 2 and cardiac notch, right has 3

Front 33

What are the accessory structures of the respiratory system?

Back 33

Oral cavity, rib cage, and things such as the intercostals and the diaphragm.
