Radial Traction Definition, Emphysema, COPD, Asthma, Pulmonary Fibrosis
The airway of lungs is composed of parenchyma. Parenchyma are the connective tissues which surrounds the lung airways. A scaffold is formed around airway due to parenchyma and this scaffold apply force on airways to make them open so that person may breathe easily. This force is known as radial traction. Whenever person inspires, the fibers of parenchyma connective tissues get stretched and make the airways wide open with the help of increased traction force. In case of expiration, the opposite phenomenon occurs in which fibers of parenchyma connective tissue contracts with the help of decreased traction force.
Emphysema is a condition in which person face shortness of breath and the elasticity of the cells of airways of lungs increases. As the elasticity increases, the cells stretch more and as a result the radial traction force of the airways increases leading to increased inhalation of air. But due to problem in the cells of air sacs present inside the lungs, person exhales immediately and less oxygen is absorbed leading to shortness of breath. Radial traction force increases during inspiration in emphysema but it is followed by sudden and increased contraction of parenchyma tissues during exhalation with decreased radial traction force.
COPD is abbreviated as chronic obstructive pulmonary disease. In this disease, there is an obstruction in the flow of air during breathing. Basically COPD is the group of diseases in which is an obstruction in the way of air during breathing. There are four main mechanisms occur during COPD. 1st one include the contraction of walls of airway which in other words is known as bronchoconstriction, Excess mucous production leading to obstruction, Inflammation of walls of airways leading to narrowing of airways and any other tissue destruction may lead to contraction of airways. All these mechanisms show narrowing of airways and loss of radial traction.
Asthma is a chronic lung disease, in which the walls of airways are inflamed and due to inflammation, the walls of airways become thick which leads to the narrowing of airways. Due to these structural changes, the radial traction force is also disturbed. Due to narrowing of airways, the radial traction force is also lost which is not good for person. Because due to lack of radial traction force, the airways may collapse during expiration phase and as a result patient may die.
Pulmonary fibrosis is a lot like emphysema, as in this disease, the tissues of lungs are damaged and scarred. These damaged and scarred tissues become thick more than a limit and causes problem during breathing. Due to thickening of cells of lungs, the airways become narrow and radial traction force is lost. When there is decreased radial traction force, the chances are high that the whole respiratory system may collapse. It is a life threatening condition. Patient try hard to inhale oxygen more during breathing but the airways does not support and all this leads to shortness of breath.
Radial Traction Emphysema
Emphysema is a condition in which person face shortness of breath and the elasticity of the cells of airways of lungs increases. As the elasticity increases, the cells stretch more and as a result the radial traction force of the airways increases leading to increased inhalation of air. But due to problem in the cells of air sacs present inside the lungs, person exhales immediately and less oxygen is absorbed leading to shortness of breath. Radial traction force increases during inspiration in emphysema but it is followed by sudden and increased contraction of parenchyma tissues during exhalation with decreased radial traction force.
