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
