18
New cards
What is inspiration?
Air is drawn into the lungs and the thoracic cavity expands, decreasing air pressure in the lungs
19
New cards
What is expiration?
Air is expelled from the lungs, the thoracic cavity contracts, increasing the air pressure in the lungs
20
New cards
Where is plueral linkage and what does it do?
between the lungs and the ribs; it enables the lungs to expand and contract as the thorax changes volume
21
New cards
Parietal Pluera
Lines the inner surface of the thoracic cavity
22
New cards
Viceral pluera
Lines the outer surface of lungs
23
New cards
Why are the pluera useful?
Provide friction free movement, protection, and link lungs to the walls of thorax
24
New cards
What is boyles law?
Pressure and volume are inversely related
25
New cards
What is the diaphragm the primary muscle of?

27
New cards
Which side of the diaphragm is higher?

28
New cards
What is the diaphragm innervated by?
Phrenic nerve
29
New cards
What is the white part in the middle of the diaphragm?
What is the white part in the middle of the diaphragm?
Central tendon
30
New cards
Where does the sternal portion of the diaphragm attach? (Muscular portion)
\
\n to xiphoid process
31
New cards
Where does the costal portion of the diaphragm attach? (Muscular portion)
to inner surface of cartilage of ribs 7 - 12
32
New cards
Where does the vertebral portion of the diaphragm attach? (Muscular portion)
to upper lumbar vertebrae (corpus of L1, transverse process of L1 – L5)
33
