Question 12

Pharynx

Answer 12

Throat
Hollow muscular structure starting behind the nasal cavity
Lined with epithelial tissue

Question 13

Three sections of pharynx

Answer 13

Nasopharynx, oropharynx, laryngopharynx

Question 14

Nasopharynx

Answer 14

Uppermost section
Lined with respiratory mucosa

Question 15

Oropharynx

Answer 15

Centre section of pharynx, behind oral cavity
Air, food, and liquid pass through

Question 16

Laryngopharynx

Answer 16

Lower most part of pharynx
Connects the larynx and esophagus
Water, food, and air pass through the laryngopharynx

Question 17

Larynx

Answer 17

Voice box
Cartilage connected by muscle and ligaments the provide movement of the vocal cords to control our speech

Question 18

Trachea

Answer 18

From the vocal cords, air enters the trachea, or windpipe
Largest pipe

Question 19

Brochi

Answer 19

Trachea branches at the centre into left and right stem bronchi

Question 20

bronchioles

Answer 20

Branching continues getting more numerous and smaller, deep into the lung segments
Smooth muscle in their walls

Question 21

Alveoli

Answer 21

Air sacs
Alveoli are covered with capillaries, where gas exchange occurs, oxygen goes into the blood

Question 22

Mediastinum

Answer 22

A region of separation, contains the esophagus, heart, great vessels, and trachea

Question 23

Pleura

Answer 23

Prevent irritation of lungs moving against the thorax, each lung is warped in a double layer sac

The rib cage Sternum Thoracic vertebrae to which each rib attaches

Question 28

Medulla oblongata

Answer 28

Control centre of the brain

Question 29

Diaphragm

Answer 29

Is sent singalong through a nerve from the brain causing it to contract and flatten

Question 30

Process of breathing

Answer 30

Inspiration is a active process Exhalation is a passive act

Question 31

Accessory muscles

Answer 31

Used to help pull up your rib cage to make an even larger space in the thoracic cavity

Question 32

Accessory muscle if exhalation

Answer 32

More forceful and active exhalation by increasing abdominal pressure Abdominal muscles

Question 33

Respiratory rate

Answer 33

Breathing rate is controlled by the level of carbon dioxide in our blood

Question 34

Pneumonia

Answer 34

Lung infection results in inflammation of infected area with an accumulation of call debris and fluid

Question 35

COPD

Answer 35

Chronic obstructive pulmonary disease Lung damage that blocks gas exchange

Question 36

Asthma

Answer 36

Difficult to get air in, more difficult to get air out resulting in inability to get enough fresh, oxygenated air in The inflammatory process causes increased secretions, blocking of the airways and further reducing the passage of air to the alveoli

Question 37

Cilia

Answer 37

Hairlike projections that moves microbes and debris up and out of the airways
