Respiratory System

Question 1

Trachea

Answer 1

The tube that runs from your mouth down the front of your chest to connect to the bronchi in the lungs.

Question 2

Bronchi

Answer 2

Tubes that branch from the trachea into smaller tubes called bronchioles, which carry oxygen into the lungs.

Question 3

Bronchioles

Answer 3

Tiny tubes branching from the larger bronchi that bring oxygen to alveoli in the lungs.

Question 4

Alveoli

Answer 4

Small air sacs at the end of the bronchioles, which are the site of gas exchange in the lungs

Question 5

Pulmonary arteries

Answer 5

Blood vessels that carry blood lacking oxygen from the heart to the lungs.

Question 6

Capillaries

Answer 6

The smallest blood vessels in the body, which are responsible for gas exchange in cells and at the alveoli.

Question 7

Pulmonary veins

Answer 7

The blood vessels that carry oxygen rich blood from the lungs back to the heart

Question 8

List the organs of the Respiratory System

Answer 8

Nose
Nasal cavity
Pharynx
Larynx
Trachea
Bronchi
Lungs

Question 9

Define the Function of the Respiratory System

Answer 9

Supplies body with oxygen and removes carbon dioxide
Provides an airway for respiration
Moistens and warms inhaled air
Filters and cleans inhaled air
Serves as resonating chamber for speech
Houses olfactory receptors

Question 10

Define the Function of the Pharynx

Answer 10

Passageway for air and food

Question 11

Define the Function of the Larynx

Answer 11

Air passageway
Prevents food from entering lower respiratory tract
Voice production

Question 12

Define the Function of Surfactant

Answer 12

Reduces surface tension

Prevents the alveoli from collapsing

Question 13

Asthma

Answer 13

A chronic inflammatory disease of the airways that causes the airways to spasm and swells periodically so that the airways narrow.

Question 14

Bronchitis

Answer 14

Inflammation of the bronchial membranes

Question 15

Carbon dioxide

Answer 15

Odorless, colorless gas formed in the tissues as a waste product, and expelled from the lungs

Question 16

Diagphram

Answer 16

Separates the thoractic cavity from the abdominal cavity.

Question 17

Expiration or exhalation

Answer 17

Breathing out

Question 18

Inspiration or inhalation

Answer 18

Breathing in

Question 19

Influenza

Answer 19

Highly infectious respiratory disease caused by airborne viral droplets occurring in epidemics

Question 20

Laryngitis

Answer 20

Inflammation of the larynx

Question 21

Oxygen

Answer 21

A colorless, odorless, tasteless gas essential to respiration used by all cells of the body

Question 22

Pneumonia

Answer 22

Inflammation of the lung in which air sacs become filled with inflammatory cells and the lung becomes solid. symptoms are cough, chest pain, fever, headache

Question 23

Tidal volume

Answer 23

The volume of air inhaled and exhaled in a normal, resting breath, typically about 500 mL.

Question 24

Cilia

Answer 24

Hairlike projections that sweep particles towards the throat

Question 25

Inspiratory reserve volume

Answer 25

Additional amount of air that can be inhaled after a normal inhalation.

Question 26

Vital capacity

Answer 26

Maximum amount of air a person can expel from the lungs after a maximum inhalation.

Question 27

Expiratory reserve volume

Answer 27

Expiratory reserve volume is the amount of extra air above a normal breath.

Question 28

Residual volume

Answer 28

Amount of air that remains in a person’s lungs after fully exhaling.

Question 29

Total lung capacity

Answer 29

The maximum amount of air that can fill the lungs.

Question 30

What reduces surface tension and keeps alveoli from collapsing?

Answer 30

Surfactant.
