Answer 2

sensing odors

Question 3

Conducting zone

Answer 3

Moves air in of the lungs

Question 4

Respiratory system

Answer 4

Is the network of organs and tissues that help you breathe

Question 5

Nose

Answer 5

The major entrance

Question 6

Pharynx

Answer 6

Is the part of the throat situated immediately posterior to the mouth and nasal cavity

Question 7

Larynx

Answer 7

Is the cartilaginous structure that connects the pharynx to the trachea and helps regulate the volume of air that enters and leaves the lungs.

Question 8

Trachea

Answer 8

Is a tube that connects the pharynx or larynx to the lungs

Question 9

Alveolar duct

Answer 9

is a tube composed of smooth muscle and connective tissue, which opens into a cluster of alveoli.

Question 10

Alveolus

Answer 10

is one of the many small, grape-like sacs that are attached to the alveolar ducts.

Question 11

Alveolar sac

Answer 11

is a cluster of many individual alveoli that are responsible for gas exchange.

Question 12

Boyle’s Law(formula)

Answer 12

P1 P1= P2 V2

Question 13

Boyle’s law (text explanation)

Answer 13

Pressure and volume are inversely related.

Question 14

inspiration

Answer 14

The process of taking air into the lungs.

Question 15

Expiration

Answer 15

The process of letting air out of the lungs during the breathing cycle

Question 16

Medulla Oblongata

Answer 16

Diaphragm contract and flattens during inhalation air rushes in

Question 17

Eupnea

Answer 17

Is a mode of breathing that occurs at rest and does not require the cognitive thought of the individual

Question 18

Diaphragmatic breathing

Answer 18

A shallow breath, called costal breathing, requires contraction of the intercostal muscles. As the intercostal muscles relax, air passively leaves the lungs.

Question 19

Hyperpnea

Answer 19

Is a mode of breathing that can occur during exercise or actions that require the active manipulation of breathing, such as singing.

Question 20

Diaphragm

Answer 20

This contraction creates a vacuum, which pulls air into the lungs

Question 21

Atelectasis

Answer 21

A condition in which the air sacs of the lungs are either partially or totally collapsed.

Question 22

Pneumonia

Answer 22

Is a lung infection that can be caused by either viruses, fungi, protists, or bacteria

Question 23

Asthma

Answer 23

Lung condition in which the body reacts to an allergy by causing constriction of the airways of the lungs

Question 24

Emphysema

Answer 24

The alveolar air sacs are destroyed and the lung itself becomes “floppy”. As the alveoli are destroyed, it becomes more difficult for gases to diffuse between the lungs and the blood

Question 25

Chronic Bronchitis

Answer 25

Inflamed airways and large amounts of sputum are being produced. As inflammation occurs, the airways swell, and the inner diameter of the airways become smaller.

Question 26

Pneumothorax

Answer 26

A pneumothorax is a condition in which there is air inside the thoracic cavity and outside the lungs, often in the pleural cavity.

Question 27

Tuberculosis

Answer 27

Is a bacterial infection that thrives in areas of the body that have high oxygen content such as the lung.
