Respiratory Physiology 2 Flashcards
inspiration reserve volume , size and place
about 3 litres, maximum intake from full tidal
tidal volume size and function
500ml, average breathing amount
inspiration capacity size and function
the total amount available to breathe in without exhaling fully first, is 3500ml, this includes tidal an inspiration reserve volume
expiration reserve volume, size and function
amount able to respire, about 1100 ml
vital capacitance size and function
Total lung volume able to breath in and out, 4.6 liters (tidal volume +inspiration reserve volume + expiratory reserve volume)
functional residual capacity size and function
Remaining lung capacity below tidal includes residual volume and expiratory reserve volume, about 1300ml
residual lung volume size and function
The remainder of the lung that cannot be exhaled, about 1200 ml
What is dead space volume, and how much of there is
150ml, air not able to be exchanged
Total lung volume size and function
vital capacitance+ residual volume about 5.8 l
pleural cavity
a very fin fluid filled sac that completely surrounds the lungs, about 3ml
visceral pleura
part of the plural membrane that is attached to the lungs
parietal pleura
Part of the membrane is attached to the exterior chest.
pneumothrax
whole in the plura, often caused by trauma, this lets air run in causing the rlung to collapse due to the outside pressure now equalling the lungs pressure , as the elastic rib mule cannot keep the chest open and pull it outwary
Boyles law
pressure is inversely proportional to the volume for a gas p = 1/v
