The left and right main bronchi

22
Q

What are the vital organs of respiration

Main function of the lungs

A

To oxygenate blood

24

A

Cervical, costal, diaphragmatic and mediastinal

27
Q

What does the visceral pleura cover

A

The surface of the lungs

28
Q

WHat is the pulmonary ligament

A

The sleeve of pleura that hangs down below the lung root

29
Q

What are the different branches of the bronchi

Main, lober and segmental

30
Q

What do the bronchioles lack

A

Cartilage

31

A

Three

32
Q

How many lober bronchi are in the left lung

A

Two

33
Q

Main function of the bronchi

A

To transport air

34
Q

What are the respiratory surfaces within the lungs

A

The alveoli

35
Q

What are alveoli

A

Air-filled sacs that are in close association with capilaries of the lung

36
Q

What is the larynx composed of

A

Epiglottic cartilage, thyroid cartilage, arytenoid cartilage and cricoid carilage

37
Q

What makes up the Adams apple

A

Thyroid cartilage

38
Q

What happens when the thyroid cartilage expands

A

The vocal folds expands which causes the voice to deepen

39
Q

What carilage connects the larynx to the trachea
