What is lung compliance?
Lung compliance = Lung expandability
What effect does a deficiency of surfactant exert on lung compliance?
Increased compliance result
Ease with which lung tissue can be stretched?
Compliance
What determines lung compliance?
Alveolar surface tension
What happens to amp draw as static pressure increases?
As your static pressure increases your Amp draw will drop
What characteristics of normal lung tissue are missing from diseased tissue?
the two main characteristics of normal lung tissue that may be affected in diseased individuals are either Compliance or Elasticity. compliance is the characteristic of lung tissue that allows it to expand elasticity is the characteristic of lung tissue that allows it go back to its former shape and size. elasticity is usually affected in chronic obstructive conditions like emphysema compliance is usually affected in restrictive lung dysfunctions like pulmonary fibrosis.
What happens to lung compliance with aging?
In aging there is usually a gradual INCREASE in the compliance of the lung tissue (i.e. a decrease in tissue elasticity). This means that the lung is more easily distended but then has more difficulty in recoiling to it's original state and so exhalation can become difficult. The compliance of the chest wall is decreased in aging, and respiratory muscles weaken, adding to this effect.
What is the effect of execersing on the rate of inhalation on lung capacity?
Exercising increases the lung capacity.
What causes static compliance in the lungs to decrease?
well .. the cause is if there is no air movement the Cst will decrease .
What happens to lung capacity as a result of long term training?
Increases
What happen to the static friction force as the mass is increased?
It increases. Static friction is the friction that opposes an object at rest to begin moving, given the following formula :- Fs = MsN, where ms is the coefficient of static friction, and n is the normal force, which is equal to mg if is at the x-axis. As the formula shows, the static friction increases with an increase in mass.
As the pull on a stationary object increases the force of static friction remains constant?
No. In order for an object to remain stationary, the forces on it must be balanced. If the pull on the object increases, the force of static friction must also increase.
