16
Q

What is the venous drainage of the intercostal areas?

A 
Azygos system (drains into the superior vena cava)
Some into the internal thoracic vein
17
Q

What is the main muscle of Inspiration?

A

The diaphragm

18
Q

What are the 3 openings of the diaphragm?

A

T8 for the vena cava
T10 for the oesophagus
T12 for the Aorta

19
Q

What are some of the accessory muscles to respiration?

A

Sternocleoidmastoid

Pectoralis major

20
Q

What does the parietal pleura cover?

A

Bony thorax
Diaphragm
Mediastinum

21
Q

What does the visceral pleura cover?

A

The lungs

22
Q

Where do the 2 layers meet?

A

At the Hilum

23
Q

What is the pleural seal?

A

The parietal and visceral pleura sit close to each other and the tension between the 2 resists them being pulled apart, pulls lung with it

24
Q

What innervates the diaphragm? & sensory supply there

A

C3, C4, C5

25
Q

What is the Costodiaphragmatic recess?

A

An extra space inferior to the lung for very deep inspiration

26
Q

How can you define the lower respiratory tract?

A

Below the cricoid cartilage

27
Q

What is the Carina?

A

Where the trachea divides into 2

Can expand due to enlarged lymph nodes & lung carcinomas

28
Q

Which Bronchi is shorter? Why is this important?

A

The right one, it is also more vertical. Important as it is more likely to have foreign bodies stick in it when inhaled

29
Q

How many lobar bronchi are there on each side?

A

3 on the right

2 on the left

30
Q

What is a bronchopulmonary segment?

A

An area of lung supplied by its own segmental bronchi and segmental branches of the pulmonary artery and vein

31
Q

How many lobes make the right lung?

A

3 lobes (superior, middle, inferior)

32
Q

How many lobes make the left lung?

A

2 lobes (superior and inferior)

33
Q

What fissures are on the right lung?

A

Horizontal

Oblique

34
Q

What fissures are on the left lung?

A

Horizontal only

35
Q

Where is the phrenic nerve and vagus nerve in relation to the hilum of the lung?

A

Phrenic infront of

Vagus behind

36
Q

What are the surface markings of the pleural cavity?

A

8th rib at the front
10th rib mid axillary line
12th rib posteriorly

37
Q

What is the surface marking for the oblique fissure?

A

T2 –> 6th costal cartilage

38
Q

What is the surface marking for the horizontal fissure?

A

4th rib and costal cartilage
