What is lung compliance?
Lung compliance = Lung expandability
What determines lung compliance?
Lung compliance is determined by the elasticity of the lung tissue and the surface tension of the alveoli. Compliance decreases with conditions that stiffen the lung tissue, such as fibrosis, or increase surface tension, such as pulmonary edema. Compliance also decreases with aging and certain diseases like chronic obstructive pulmonary disease (COPD).
What are some factors that increase the chance of lung cancer?
smoking.
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 effect does a deficiency of surfactant exert on lung compliance?
Increased compliance result
What causes static compliance to decrease?
Static compliance decreases due to factors like pulmonary fibrosis, lung tissue scarring, or poor surfactant function which results in reduced ability of the lungs to stretch and expand during inhalation, leading to decreased lung capacity and restricted airflow.
Ease with which lung tissue can be stretched?
Compliance
What is the difference between chest wall compliance and lung compliance, and how do they affect overall respiratory function?
Chest wall compliance refers to the ability of the chest wall to expand and contract during breathing, while lung compliance refers to the ability of the lungs to stretch and expand. Chest wall compliance can affect the pressure inside the chest cavity, while lung compliance affects the ease of lung expansion and air flow. Together, they determine how easily air can move in and out of the lungs, impacting overall respiratory function.
How do you develop lung cancer and what are the risk factors associated with it?
Lung cancer develops when abnormal cells in the lungs grow uncontrollably. The main risk factors for developing lung cancer include smoking, exposure to secondhand smoke, radon gas, asbestos, and air pollution. Family history, age, and certain genetic factors can also increase the risk. Early detection and avoiding these risk factors can help prevent lung cancer.
What factors increase the chances of a person developing byssinosis?
Smoking, impaired lung function, and a history of respiratory allergy increase a textile worker's risk of developing byssinosis.
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 disorders increase a person lung capacity?
Lung capacity can not be increased by a disorder.
