A

Pneumothorax

25
Q

Procedure to obtain fluid sample, or to drain blood/pus

A

Thoracentesis

26
Q

During a thoracenteses, what does the clinician need to do?

A

.

27
Q

Where is the needle inserted for a thoracentesis?

A

.

28
Q

lung which has a groove for the esophagus

A

right lung, although a small area on the left does exist

29
Q

Seperates the sup and inf lobes of the lungs

A

Oblique fissure

30
Q

Lung which has a horizontal fissure

A

the left lung, since it has three lobes

31
Q

lung which has a large groove for the aorta

A

the left lung,

32
Q

which lung has a present groove for the subclavian a. and the brachiocephalic vein?

A

Left lung

33
Q

Which lung has a large, inferior cardiac notch and impression?

A

Left lung

34
Q

Which lung has a lingula?

A

Left lung

35
Q

Which lung has a large groove for the esophagus, and the azygos vein?

A

The right lung

36
Q

Which lung has a large impression for the thymus?

A

The left lung

37
Q

Describe the branching of the tracheobranchial tree

A

From superior to inferior..

the trachea bifurcates at the sternal angle into the Right and Left main bronchi.

the R main bronchus branches into the R Sup, middle, and inf bronchus (3)

the L main bronchus branches into the Sup. lobar bronchus and the L inf lobar bronchus

38
Q

Which lung has a middle lobar bronchus?

A

The Right Bronchus/thus R lung ONLY, the left side only has two branches which correspond to its TWO LOBES

39
Q

The trachea bifurcates into the L and R main Bronchi at what anatomical level

A

At the sternal angle

40
Q

The trachea splits at the level of the sternal angle, the bifurcation is marked by an internal structure which divides the two resulting bronchi called _______

A

Carina

41
Q

The three bronchopulmonary segements from sup to inf are ?

A

Main bronchus –> Lobar bronchus –> segmental bronchus

42
Q

Why are segments of the lungs relevant? (2)

A

For understanding blood supply,, ventilation, and lymphatic drainage

Also for managing infection and cancer

43
Q

If one is to aspirate a small material (i.e. a dental dam retainer, damn things), where is it most likely to end up and why?

A

The Right internal segment because the Right Main bronchus is more vertically in line with the trachea than is the L side

44
Q

The Pulmonary trunks into (2), these then go –> ______ –> _____

A

The pulmonary trunk splits into the R and L pulmonary arteries which go to the lobar arteries –> segmental arteries

45
Q

The pulmonary vein drains into where?

A

the left atrium

46
Q

The lobar veins converge onto the pulmonary veins, what converged on the lobar veins before that?

A

Segmental veins –> lobar veins –> pulmonary veins –> Left atrium

47
Q

Segmental veins –> –> –> –> Finish this

A

Segmental veins –> Lobar veins –> pulmonary veins –> LA

48
Q

At the root of the lung, you will see how many pulmonary arteries on each side? Pulmonary veins?

A

.

49
Q

Describe the hilum of the Right Lung

A

Sup to inf

Bronchus
Artery
Vein

50
Q

Describe the hilum of the left lung

A

From sup to inf

Artery
Bronchus
Vein

51
Q

Which lung has a hilum in which the pulmonary vein is the most inf structure?

A

BOTH

52
Q

Which lung has a hilum in which the bronchus is the most sup structure?

A

The R lung

53
Q

What accessory things to the normal hilum may be present in the lungs?

A

lymph nodes

54
Q

Describe the lymphatic drainage of the lungs (collects where… drain where)

Left and right

A

Collects in the pulmonary nodes –> bronchopulmonary nodes (hilar nodes) –> tracheobronchial nodes (sup and inf)

from here…
1. drainage may pass sup or lateral (to bronchomediatinal trunk)

–> deep cervical nodes —> supraclavicular nodes may recieve multiple

NOW left or right

Right –> R lymphatic duct
LEFT –> Thoracic duct

–> all drain into the subclavian vein along the bronchomediastinal trunk

55
Q

All the lymphatics of the lungs drain where which is situated where

A

the subclavian vein which is along the bronchomediastinal trunk
