Q

The lungs are divided into

A

lobes

21
Q

Right lung has three lobes

A

superior lobe, middle lobe and inferior lobe

22
Q

Left lung has only two lobes;

A

superior lobe and inferior lobe

23
Q

the openings of the nose where the air enter first

A

Nostrils

24
Q

the pair of passages way inside the nostrils which is separated from each other by a bony partition called Nasal Septum.

A

Nasal Cavity

25
Q

the nostrils which is separated from each other by a bony partition called

A

Nasal Septum

26
Q

hairlike projections which lined the nasal cavities

A

Cilia

27
Q

filter the air and trap dust and other particles

A

Cilia

28
Q

also called throat

A

Pharynx

29
Q

Passageway that is divided into two smaller passages

A

Pharynx

30
Q

Commonly known as voice box

A

Larynx

31
Q

Located between the pharynx and the trachea

A

Larynx

32
Q

Place where voice is produced through vocal cords

A

Larynx

33
Q

The space between the vocal cords is called

A

glottis

34
Q

A flap of elastic tissue that forms a cover on top of the larynx

A

Epiglottis

35
Q

This structure ensures that food and air enter the body through different pathways

A

Epiglottis

36
Q

also called windpipe

A

Trachea

37
Q

The main passageway of air into the lungs

A

Trachea

38
Q

It is supported by C-shaped rings of cartilage that prevent it from collapsing during inhalation

A

Trachea

39
Q

The two main stems which lead to the lungs

A

Bronchi

40
Q

Each bronchus enters the lung at a depression called

A

hilus or hilum

41
Q

Are the smallest conducting tubes inside the lungs

A

Bronchioles

42
Q

also known as air sacs

A

Alveoli

43
Q

Place where exchange of gases occur

A

Alveoli

44
Q

A respiratory disorder characterized by restriction in the movement of air due to recurring episodes of contractions of the bronchial smooth muscle.

A

Asthma

45
Q

An inflammation of the bronchi that may result in swelling of the bronchial lining, narrowing of the air passages, and shortness of breath

A

Bronchitis

46
Q

Often referred to as chronic obstructive pulmonary disease.

A

Emphysema

47
Q

Results from the gradual destruction of walls of the alveoli

A

Emphysema

48
Q

As a result, gas exchange is decreased and air is retained in the lungs in most cases

A

Emphysema

49
Q

Uncontrolled or unregulated division of the cells lining the respiratory tract which resulted to tumors that can grow and multiply

A

Lung Cancer
