Respiratory system Lungs pt. 2 (EXAM 1)

Question 1

Upper cavity

Answer 1

Thorax (chest)
thoracic cavity is the space within the ribcage
contains the lungs and the heart
mediastinum (middle of lungs) houses the heart, multiple blood vessels, and esophagus

Question 2

Lungs

Answer 2

located within rib cage/Thoracic cavity
has 2 thin delicate CT pleural membranes:
1. Parietal pleural membrane
2. Visceral pleural membrane

Question 3

Parietal Pleural membrane

Answer 3

Inner surface of T.C.. (outside/surrounding/around)

Question 4

Visceral pleural membrane

Answer 4

Outer surface of lungs (Vicinity)

Question 5

Ribcage

Answer 5

Surrounds lungs, connected with lungs via pleural linkage

Question 6

Pleural potential “space”

Answer 6

Is not actually a cavity type of space
filled with pleural fluids
Fluids link together the 2 membranes (ST)
Allows for lubrication/smooth movement

Question 7

Pleural linkage

Answer 7

Visceral and parietal pleural membranes are linked together via:
1. Surface Tension
2. Negative Intrapleural linkage

Question 8

Surface Tension

Answer 8

Potential space between membranes actually filled with fluid, ST attracted to each other

Question 9

Negative Intrapleural linkage

Answer 9

VACUUM
Based on Magde burg principles
Suction cups
resists the pulling apart of the lungs and ribcage
links lungs and TC

Question 10

Pulmonary apparatus and thoracic unit

Answer 10

Lungs and T.C. are linked by pleural linkage, functions as single unit
lungs at rest want to collapse (air sacs) without T.C., T.C. at rest wants to expand without lungs
together: perfect
As a result, when T.C. moves, lung move as well

Question 11

Pleurisy

Answer 11

Inflammation of pleural membrane
rubbing of membranes hurt, hurts more with deeper breath

Question 12

Punctured lungs

Answer 12

Breaking pleural linkage
lungs naturally collapse, T.C. naturally expands
