Flashcards in lungs Deck (28):
1

trachea

has 16-20 rings of cartilage for support

2

carina

where trachea bifurcates

3

primary bronchi

one to each lung

4

secondary bronchi

one to each lobe

5

tertiary bronchi

one to each segment

6

ant border of lungs

sharp edge

7

oblique fissure

divides lunges into upper and lower lobes on the left and upper and middle on the right

8

lingula

on the left lung, tounge like, covers the heart

9

horizontal fissure

on the right lung, divides upper lobe into upper and middle

10

difference between bronchopulmonary segments on right and left lung

right: has middle lobe with medial and lateral segments
left: has superior and inferior lingular segments in the upper lobe

11

hilum

where the vessels enter the lungs

12

bronchi on right lung

post and sup

13

pulm v's on both lungs

ant and inf

14

right pulmonary artery on right lung

more superior to vein

15

left pulmonary artery on left lung

most superior

16

pulmonary arteries

bring unoxygenated blood to the lungs
travel with bronchial tree

17

pulmonary veins

bring oxygenated blood from heart to lungs
travel separate from tree

18

bronchial arteries

supply bronchi, smaller than pulmonary, travel with bronchi

19

pleura

double layered sac, fluid secreting membranes

20

parietal pleura

lines the inner surface of the thoracic cage

21

innervation of parietal pleura

central diaphragmatic: phrenic, C345
remainder: intercostal
*somatic pain, sharp and localized

22

visceral pleura

attaches to lungs
no pain

23

pleural cavity

space btw pleura
serous fluid
hydrothorax: excess fluid in space
pneumothorax: air in space
both collapse lung

24

costal reflections at

8th rib, midclavicular line
10th rib mid axillary line
12th rib at midpt of shaft

25

lungs end at

6 8 10

26

pleura ends at

8 10 12

27

difference in pleural endings and lung endings result in

recesses

28

recesses

space not filled during normal inspiration
in full inspiration it can be filled
