Inspiratory Capacity (IC)
The maximum volume of air that can be inspired after reaching
the end of a normal, quiet, expiration.
Functional Residual Capacity (FRC)
The volume remaining in the lungs after a normal, passive
exhalation.
Tidal Volume (TV)
The amount of air that moves in our out of the lungs with each
respiratory cycle.
Inspiratory Reserve Volume (IRV)
The extra volume of air that can be inspired with maximal effort
after reaching the end of a normal, quiet inspiration.
Expiratory Reserve Volume (ERV)
The extra volume of air that can be expired with maximum
effort beyond the level reached at the end of a normal, quiet
expiration.
Residual Volume (RV)
The amount of air that remains in a person's lungs after fully
exhaling.
12-16 breaths/min
,Average adolescent respiratory rate
Pneuomothorax
A collapsed lung, occurs when air leaks into the space between
lung and chest wall.
Acute sinusitis
A condition in which the cavities around the nasal passages
become inflamed.
COPD
Chronic inflammatory lung disease that causes obstructed
airflow from the lungs
H1N1
Aka Swine flu; primarily caused by the H1N1 strain of the flu
virus.
Astham
arteries
- elastic
- no valves
- carry blood away from the heart
- high blood pressure
- thick walls
- scalloped lumen (elastic fibers) so can expand/contract with
BP
veins
, - less elastic
- one way valves
- carries blood to the heart
- low blood pressure
- flat lumen (not elastic)
capillaries
- 5-10 micrometer diameter
- network of vessels superimposed on body tissue
- thin walls for gas/nutrient exchange
walls of arteries and veins
tunica intima, tunica media, tunica externa
structure of capillaries
- 2 layers
- comprised of endothelial cells surrounded by a basement
membrane
- simple to allow exchange
tunica intima
- innermost layer
- lines the lumen of the vessel
- made up of three sublayers
sublayers of tunica intima
endothelium, subendothelial layer, internal elastic membrane
endothelium of tunica intima
