What separates the lungss?

A

Mediastinum

28
Q

What enters through the Helium to the lungs?

A

Bronchi
Vessels
Nerves

29
Q

What disease happens at the Apex of the đŸ« . Just above the clavicle?

A

Tuberculosis

30
Q

What’s it called at the apex ?

A

Apical TB

31
Q

What’s it called when TB spreads throughout the lungs ?

A

Milliary TB.

32
Q

What exposes he lungs exactly underneath the sternum

A

Cardiac knotch

33
Q

What lies in the helium what goes in through to the lungs.
Hint: Nodes

A

Bronchus
Pulmonary artery
Pulmonary vein
Lymph nodes

34
Q

What is the basic unit unit of gas exchange?

A

Alveolis

35
Q

What do alveolar cells produce ?

A

Surfactant

36
Q

From the nasal passage name everything orderly up until the alveoli.

A

Nasal cavity > pharynx > Larynx > primary bronchus > secondary bronchus > bronchiole > terminal bronchiole > respiratory bronchiole > alveolar duct > Alveoli

37
Q

Where does the heart sit?
Hint: it’s not the mediastinum 😜

A

Cardiac knotch

38
Q

What two circulations does the lungs receive from the blood?

A

Systemic and pulmonary circulation

39
Q

How do the lungs get their oxygenated blood from which artery ??
Hint: use lung related words

A

Bronchial arteries

40
Q

Which veins carry the deoxygenated blood from the lungs to the ❀?
Hint: Use lung related words

A

Bronchial veins

41
Q

What are the lobules supplied by?

A

Bronchioles

42
Q

What is pneumothorax ?

A

Air building-up in lung area

43
Q

What is a Heamothorax

A

Build-up of đŸ©ž in lungs

44
Q

what type of muscle is the diaphragm ?

A

Skeletal muscle

45
Q

Which scientist said: Air can go from high to lower pressure.

A

Dalton

46
Q

Is it a passive process when expiration occurs?
Why is this

A

Yes it’s passive
Why? Because there is no involvement of muscle contraction

47
Q

Blowing / forceful breathing is passive or active process and why?

A

Active process
Why? Because there are muscles being contracted.

48
Q

What is Tidal volume ?

A

Volume of aid which enters the body in each breath !

49
Q

What is minute volume

A

Volume of air that is inhaled each minute

50
Q

In a healthy adult how many breaths do they do in 1 minute

A

12-15 per/min

51
Q

How many mls is inhaled per breath

A

500mls

52
Q

How many is 500mls in litres

A

6-8L/min

53
Q

What is the partial pressure of gases at sea level ?

A

760 mmHG

54
Q

What does CPAP stand for

A

Continuos possitive airway pressure

55
Q

Why is surfactant so important ?

A

Prevents complete collapse of the lungs

56
Q

What is surface tension?
Explain the bubble theory

A

Surface tension is the water on the outside of the bubble trying to burst the bubble.
Surfactant anatomically prevents the collapse of the alveoli

57
Q

What happens with near drowning patients. And the surfactant??

A

Surfactant is washed out and causes the collapse of lungs đŸ«

58
Q

What’s secretes surfactant ?

A

Alveolar cells

59
Q

Why can’t we expire completely ??

A

Because surfactant prevents the full collapsing of alveoli

60
Q

What causes hypercarbia

A

Metabolic disorders like hyperthyroidism and hypothyroidism

61
Q

What causes acute respiratory distress syndrome

A

Surfactant not being present

62
