Thorax & lungs Assessment Flashcards
- lungs, trachea, bronchi
LOWER RESPIRATORY SYSTEM
extending base of neck to the diaphragm; contains the
lung portion of the trachea
THORAX
cone shape; support & protection; outer
structure; Sternum, 12 pairs of ribs & 12 thoracic vertebrae,
muscles, cartilage
THORACIC CAGE
breastbone
a. STERNUM -
connects to the clavicle & first 2 pairs of
ribs
MANUBRIUM -
articulates with 3-7th ribs
BODY OF STERNUM
main structure of the thoracic cage
RIBS
1-6
- true ribs; connected to manubrium
7-10
- false ribs; connected to cartilage
11-12 -
floating ribs; connected to spine
spine or backbone; 33 vertebrae
VERTEBRAL COLUMN
5 REGIONS
- C1-C7 - cervical
- TH1-TH12 - thoracic
- Lumbar
- Sacral
- coccygeal
- Vertebra prominens
- Scapula
- Spinous process
- 12th rib
Posterior thoracic landmark
space that contains respiratory components
THORACIC CAVITY
space b/w lungs
Mediastinum -
windpipe
➢ TRACHEA -
c shaped
Hyaline cartilag
major organ suspended in thoracic cavity; apex- up
base- lower; base of neck to diaphragm
➢ LUNGS -
- narrow
a. Left lung
- broad bc of the liver under the ribcage
Right lung -
double layered
PLEURAL MEMBRANE -
lines chest cavity
PARIETAL PLEURA
ines intercostal spaces
. VISCERAL PLEURA
- allow movement of layers ; 3rd space
for fluid storage
PLEURA SPACE
diaphragm contracts
. Vertical expansion
intercostal muscle lift sternum
Horizontal expansio
- diaphragm rises and recoils; dome shape
EXPIRATION
increase in CO2 level
HYPERCAPNIA
decrease in O2
Hypoxemia
