Q

What are notable surface impressions on the right lung?

A 
azygous vein groove
right brachiocephalic vein
superior vena cava
esophagus
heart or cardiac impression
17
Q

What are some surface impressions of the left lung?

A

more prominent esophagus groove
thoracic aorta
left subclavian artery
heart

18
Q

What is the structure of the trachea?

A

15-20 c shaped cartilage rings that face anterior

the trachea branches into primary bronchi. the point of bifurcation is called carina

19
Q

Describe the right primary bronchi?

A

wider and more vertical than the left bronchus.

20
Q

Which primary bronchi are more likely to be experience aspiration?

A

the right primary bronchi

21
Q

Describe the left primary bronchi

A

slightly more horizontal and narrower

22
Q

How many secondary lobar for the right lung?

A

there are three:

superior, middle, and inferior

23
Q

How many secondary lobar for the left lung?

A

two superior and inferior

24
Q

How many teritary bronchi on the right?

A

10

25
Q

how many tertiary bronchi on the left

A

8

26
Q

What tissue lines the primary bronchi?

A

epithelium of pseudostratified columnar with goblet cells.

27
Q

What is a bronchopulmonary segment?

A

anatomical, functional, and surgical unit of the lungs. These are separated by a thin connective tissue that helps slow the spread of disease and also makes the segments easy to remove if diseased.

28
Q

What is the primary site of gas exchange?

A

is the alveoli, here capliaries form around the alveoli.

29
Q

What causes asthma?

A

the overstimulation of the parasympathetic system

30
Q

How do you treat asthma?

A

with drugs that mimic theh sympathetic response

31
Q

how does asthma occur?

A

parasymp overstimulation:

this leads to more blood flow, more basophils, more histamine, and more inflammation which leads to less air.

32
Q

How is lymph drained from the lungs?

A

the lymph nodes around the bronchi and connective tissue collect carbon, and other pollutants that are not filtered out already. this then travel reversely up the pulmonary tree and dumps into the veins.

33
Q

What is an important stage in lung development?

A

canalicular just know it grant.

34
Q

What is pneumonia?

A

infection of the alveoli where the alveolar walls swell. There is an increase in WBC. This reduces the capactiy for gas exhcangfe.

35
Q

What is emphysema

A

the main form of COPD.

elastic tissue is destroyed and therefore have less gas exchange.

Barrell chest is a common symptom.

36
Q

What are some symptoms of lung cnacer?

A

chronic cough, hemotysis (coughing blood), excess pulmonary muscus production and increased infections.
