Thorax and Lungs Flashcards
mediastinum and lungs lined by pleural membrane
thoracic cavity
flexible, 10-12cm long with C-shaped hyaline cartilage
trachea
Linus thoracic cavity
pleura
lines chest cavity
parietal pleura
covers the external surface of the lungs
visceral pleura
fluid; stop lung sounds due to friction
pleural space
decrease in oxygen and increase in respiration
hypoxemia
increase in CO2 in blood
hypercapnia
percussion tone, flat tone in scapula
resonance
higher on left bcoz of liver
disphragm
normal breathing sound of bronchovesicular
medium pitch and muffled
normal breathing sound of bronchial
high pitch and loud
normal breathing sound of vesicular
low pitched
adventitious lung sounds
crackles and wheezes
from the base of neck through diaphragm
thorax
the distal portion of the trachea, elastic and not symmetric
lungs
thoracic cage
sternum
12 pairs of ribs
12 thoracic vertebrae
muscles and cartilage

sternum
sternum is divided into 3:
manubrium
body
xiphoid process
connects laterally with clavicles and two pairs of ribs
manubrium
third to the seventh rib
body (sternum)
the inferior part of the sternum
xiphoid process
U-shaped indentation
suprasternal notch
bony ridge
sternal/angle of lovis
location of 2nd rib which is referred for counting ribs/spaces
sternal/angle of lovis
costal margins meeting at xiphoid process
costal angle
the 11th and 12th rib
not conected to sternum, but in vertebra
floating ribs
abnormal rapid breathing
tachypnea
difficulty breathing
dyspnea
breathing slowly than normal
bradypnea
sunken sternum/breastbone
pectus excavatum
breastbone protruded forward
pectus carinatum
