Question 5

nasal cavity

Answer 5

large air filled space above and behind the nose, each nostril leads to its own nasal cavity

Question 6

what does conchae mean

Answer 6

any spongy bone found outside the nasal cavity

Question 7

Function of nasal cavity (2)

Answer 7

warm and filter air, provide a place for air to enter the body

Question 8

Function of sinuses (3)

Answer 8

1. keeps nasal cavity moist
2. protects from dust partials/bacteria to enter the body
3. Warms incoming air

Question 9

3 parts of the pharynx (throat)

Answer 9

Nasopharynx, laryngopharynx, oropharynx

Question 10

Nasopharynx connects the

Answer 10

Pharynx to the nose

Question 11

oropharynx connects the

Answer 11

mouth to the pharynx

Question 12

Laryngopharynx function

Answer 12

helps guide food and air

Question 13

Point out the parts of the pharynx

Answer 13

Nasopharynx, laryngopharynx, oropharynx (on photo)

Question 14

label the nasal cavity (8)

Answer 14

Frontal sinus, middle nasal concha, inferior nasal concha, external naris, spheroid sinus, internal naris, nasopharyx

Question 15

larynx function

Answer 15

produce sound

Question 16

what is the larynx made of?

Answer 16

muscles and cartilage

Question 17

how the larynx produce sound?

Answer 17

When air travels it uses it to create pressure that vibrates the vocal cords

Question 18

label the muscles on the larynx

Answer 18

Epiglottis, vocal cords, trachea, cartilage

Question 19

Why is the Epiglottis important?

Answer 19

It allows food and liquids to enter the digestive tract

Question 20

Where is the trachea

Answer 20

leads to the lungs from the larynx

Question 21

why is it important that the trachea is fileable?

Answer 21

allows for airflow when breathing

Question 22

what is the bronchi?

Answer 22

the passageways that connect your windpipe to your lungs

Question 23

what is the function of the
small bronchi within the lungs?

Answer 23

to increase the rate which oxygen leads into the lungs/bloodstream

Question 24

label components of the bronchi (8)

Answer 24

Larynx, trachea, primary, secondary, tertiary bronchi, pulmonary artery, vain and alveolar duct

Question 25

The lungs are divided into systems called

Answer 25

lobes

Question 26

why does the right lung have 3 lobes, but the left lung has 2?

Answer 26

the left lung is smaller due to the location of the heart

Question 27

label the lungs (11)

Answer 27

superior lobe, middle lobe, inferior lobe, trachea, superior lobe, primary, secondary, tertiary bronchus, cardiac notch, inferior lobe

Question 28

terminal bronchioles

Answer 28

the last conducting airway

Question 29

terminal bronchioles lead to the alveoli which is

Answer 29

Small air sacs

Question 30

Alveoli are covered in

Answer 30

capillaries, tiny blood vessels which lead to the veins

Question 31

label the bronchiole

Answer 31

Alveolar sacs, Alveoli, pulmonary artery, bronchiole, pulmonary vein

Question 32

respiratory membrane

Answer 32

the surface where gas exchange between the alveoli and blood occurs in the lung

Question 33

respiratory membrane function

Answer 33

allows gases to cross by simple diffusion

Question 34

The diaphragm function

Answer 34

The diaphragm is a muscle that helps you inhale and exhale (breathe in and out)

Question 35

the diaphragm

Answer 35

The major muscle of respiration.

your diaphragm contracts (tightens) and flattens, moving down towards your abdomen

Question 36

Inspiratory capacity

Answer 36

The max volume of air that can be inhaled normally

Question 37

Expiratory reserve volume

Answer 37

amount of extra air above normal that you exhale during a forceful breath out

Question 38

explain Boyle’s law

Answer 38

as volume increases, pressure decreases, as volume decreases, pressure increases.

Question 39

tidal volume

Answer 39

the amount of air that moves in or out of the lungs with each respiratory cycle.

Question 40

inspiratory reserve volume

Answer 40

the amount of air that enters the lungs when a person inhales past the tidal volume.

Question 41

residual volume

Answer 41

the volume of air remaining in the lungs after maximum forceful exhale

Question 42

vital capacity

Answer 42

Max volume of air that can be exhaled after taking the deepest breath

Question 43

Functional residual capacity

Answer 43

Volume remaining in lungs after a normal exhale

Question 44

Total lung capacity

Answer 44

total volume the lungs can hold

Question 45

Explain how air and blood exchange gasses using partial pressure and diffusion

Answer 45

the partial pressure of oxygen is lower in the blood entering the lungs than it is in the alveolar gas, oxygen diffuses into the blood

Question 46

Describe how oxygen and carbon dioxide are transported in the blood

Answer 46

dissolved directly in the blood, bound to plasma proteins or hemoglobin, or converted into bicarbonate.
