Q
Dalton’s law
A
states that total pressure is exerted by the mixture of non reactive gases is equal to the sum of partial pressures of individual gases
1
Q
LaPlaces Law
A
a principle in physics that the tension n the wall of a sphere is the product of the pressure time the radius of the chamber and the tension is inversely relates to the thickness of the wall.
2
Q
type 1 alveolar cell
A
97% of the surface, very thin gas permeable component of the blood air barrier
3
Q
type 2 alveolar cell
A
interspersed throughout type 1 and are secretory cells that secrete surfacant
4
Q
surfactant
A
is a complex naturally occuring substance that is made of six lipids and four proteins that is produced by the lungs, helps reduce surface tension.
