Lungs and Pleura

Question 1

Mediastinum

Answer 1

Inserted between the right, and left lungs and their pleura

Question 2

visceral pleura

Answer 2

Line the lungs

Question 3

parietal pleura

Answer 3

Line the walls of the thoracic cavity

Question 4

where does the visceral and parietal pleura come together?

Answer 4

They come together, and become continuous at the root of the lung

Question 5

parietal pleura parts

Answer 5

Costol pleura- lining thoracic walls
Diaphragmatic pleura- lining of the diaphragm
mediastinal pleura- lining of the mediastinum

Question 6

right lung

Answer 6

Three lobes, superior, middle and inferior

Lobes are separated by horizontal and oblique fissures

Question 7

Left lung

Answer 7

two lobes superior and inferior

lobes are separated by an oblique fissure

Question 8

Bronchial tree

Answer 8

each lung receives a primary or principal bronchus from the trachea

Each principal bronchus divides into lobar bronchi which supplies a lobe of the lung

each lobar bronchus divides into tertiary segmental bronchi, which supplies a specific bronchopulmonary segment

Question 9

what supplies venous blood to the lungs of the aeration?

Answer 9

The branches of the pulmonary arteries

Question 10

pulmonary arteries run with

Answer 10

The bronchi and lie posterior to them

Question 11

there are no arterial anastomoses between

Answer 11

Bronchopulmonary segment

Therefore, removal of a pulmonary segment of the lung will not in danger of the viability of the adjacent segments

Question 12

The pulmonary veins drain

Answer 12

Oxygenated blood to the left atrium of the heart

Question 13

superior and inferior pulmonary veins are formed at

Answer 13

hilus of each lung

Question 14

superior pulmonary veins receives tributary’s from

Answer 14

The superior and middle lobes of the right lung
and superior and lingula lobes of the left lung

Question 15

Inferior pulmonary veins received tributaries from

Answer 15

The lower lobes of the right, and left lungs

Question 16

hilum of the lung

Answer 16

Or Root

attachment point of the lung

Connects the lungs to the heart and trachea
Surrounded by the reflection of parietal to visceral pleura

Provide highway for the main bronchus, pulmonary vessels, bronchial vessels, lymph vessels, and nerves

Question 17

Lymphatic drainage

Answer 17

Superficial lymphatic drains to the surface and runs along the visceral pleura to the hilum

lymphatic drainage follows the bronchi and collects at the hillum

at hillum, lymphatic drainage is filtered by the tracheobronchial nodes

Question 18

parietal pleura, and thoracic wall superiorly

Answer 18

pleura extends through the thoracic inlet it is called a cupula of the pleura

Question 19

parietal pleura and thoracic wall inferiorly

Answer 19

pleura related three ways

Anterior- 7 costal cartilage
Midaxillary- 10th costal cartilage
Posterior- 12 vertebral level

Question 20

Costodiaphragmatic recess parietal pleura and thoracic wall

Answer 20

Separation of parietal pleura from visceral pleura for the costal and diaphragmatic pleura meet

Question 21

Lungs to thoracic wall superior

Answer 21

Lung extends through the thoracic inlet as the apex of the lung

Question 22

lungs to thoracic wall anterior

Answer 22

The lung extends down to the sixth costal cartilage

Question 23

lungs to thoracic wall midaxillary

Answer 23

The lung extends down to the eighth costal cartilage

Question 24

Lungs to thoracic wall posterior

Answer 24

Lung extends down to the 10th or 11th rib

Question 25

Bronchopulmonary segment

Answer 25

Largest subdivisions of a lobe

Pyramid shaped segments

apexes facing the root of the lung
base at the pleural surface

Separated from adjacent segments by connective tissue septa

Supplied independently by segmental bronchus in a tertiary branch of the pulmonary artery

Named according to the segmental bronchi supplying them

Drained by intersegmental parts of the pulmonary veins that live in the connective tissue between and drain adjacent segments

usually 18 to 20 in number
10 in the right lung, 8 to 10 in the left lung

Surgically resectable

Question 26

Posterior
Anterior

Question 27

middle lobe segment, right lung

Answer 27

Lateral
medial

Question 28

anterior lobe segments, right lung

Answer 28

Superior
Anterior basal
Medial basal
lateral basal
Posterior basal

Question 29

apicoposterior part of superior lobe segments for left lung

Answer 29

apical
Posterior
Anterior

Question 30

superior lobe segments for left lung

Answer 30

superior lingular
Inferior lingular

Question 31

anteromediobasal part of the inferior lobe segments of the left lung

Answer 31

Anterior basal
Medial basal

Question 32

inferior lobe segments of the left lung

Answer 32

superior
Lateral basal
Posterior basal
