Question 1

Ventilation

Answer 1

The amount of gas reaching the alveoli

Question 2

Respiratory system

Answer 2

Supply blood with oxygen for cellular respiration and dispose of carbon dioxide

Question 3

Chemical equation

Answer 3

C6H12O6 + 6O2 —> 6CO2 + 6H2O + ATP

Question 4

Respiratory System Processes

Answer 4

Pulmonary ventilation (breathe): movement of air into and out of lungs

External respiration: exchange of O2 and CO2 between lungs

Question 5

Circulatory System Processes

Answer 5

Transport of O2 and CO2 in blood

Internal Respiration: exchange of O2 and CO3 between capillaries and tissues

Question 6

Proper terms for inhale and exhale

Answer 6

Inhale: inspiration

Exhale: expiration

Question 7

Upper respiratory system organs

Answer 7

Nose and nasal cavity

Paranasal sinuses

Pharynx (throat)

Question 8

Nose and Paranasal sinuses

Answer 8

Provides airways for respiration

Moistens and warms entering air

Filters and cleans inspired air

Serves as resonating chamber for speech

Houses olfactory System

Question 9

2 regions of the nose

Answer 9

External nose

Nasal cavity

Question 10

Nasal conchae/ turbinates

Answer 10

During inhalation, conchae and nasal musical filter, heat, and moisten air

During exhalation these structures reclaim heat and moisture

Question 11

Nasal cavity

Answer 11

Within and posterior to external nose

Collated cells sweep contaminated mucus posterior your towards throat

Contains sensory nerve endings that causes sneezing

Question 12

Nasal cavity division

Answer 12

Divided by midline nasal septum

• septal cartilage, comer bone, and ethmoid bone
• serous mucus nasal glands contain mucus secreting mucous cells and serous cells

Question 13

Paranasal sinuses

Answer 13

Form ring around nasal cavities

Located in frontal, sphenoid, ethmoid, and maxillary bones

Lighten skull

Secrete mucus

Help warm and moisten air

Question 14

4 Paranasal sinuses

Answer 14

Frontal

Ethmoid

Nasal

Maxillary

Question 15

Pharynx

Answer 15

Funnel-shaped, muscular tube that runs from base of skull to vertebra C6

• connects nasal cavity and mouth to larynx and esophagus
• composed of skeletal muscle

Question 16

3 regions of the pharynx

Answer 16

Naso-

Oro-

Laryngo-/hypo-

Question 17

Mucous membrane

Answer 17

Moistens air as it passes through the nasal cavity

Question 18

Nasopharynx

Answer 18

Posterior to nasal cavity

Lining contains pseudo stratified columnar epithelium

Soft palate and uvula close it during swallowing

Question 19

Nasopharynx tubes

Answer 19

Pharyngotympanic Tubes/Eustachian tubes/auditory tubes

Drain and equalize pressure in middle ear and open into lateral walls

Question 20

Oropharynx

Answer 20

Passageway for food and air from level of soft palate to epiglottis

Lining consists of stratified squamous epithelium

Question 21

Laryngopharynx

Answer 21

Food and air passageway

Posterior to upright epiglottis

Extend to larynx, where it is continuous with esophagus

Lined with stratified squamous epithelium

Question 22

The 5 Arteries

Answer 22

Superior labial artery

Sphenopaltine Artery

Internal carotid artery

External carotid artery

Anterior labial artery

Question 23

Bones of the nose

Answer 23

Perpendicular plate of ethtmoid bone

Vomerine bone

Nasal cartilage

Vomer

Palatine

Maxilla

Greater alar cartilage

Septal cartilage

Question 24

Rhinitis

Answer 24

Inflammation of nasal mucosa

Infections spread from nose to throat to chest because of respiratory tract

Spread to tear duct and Paranasal sinuses causing blockage of sinuses resulting in sinitis

Lead to absorption of air producing vaccines resulting in sinus headache

Question 25

Tonsillitis

Answer 25

Infected and swollen adenoids block air passageway In nasopharynx

Air is not properly moistened, warmed, or filtered before reaching lungs

Adenoids chronically enlarged disturbing speech and sleep
