Emphysema
This condition is known as emphysema. It is characterized by damage to the alveoli in the lungs, leading to a loss of elasticity in the alveolar walls. Over time, this can result in the alveoli becoming over-inflated and eventually rupturing, causing difficulty breathing and other respiratory issues.
The loss of elasticity of the alveoli is caused by high pressure in the bladder causing an unsafe drop in blood pressure which will cause alveoli to lose their elasticity. It can also be caused by being overweight, underweight, or eating feces.
The alveoli lose their elasticity and thus when you breathe in, not as much oxygen is taken in and transferred to the red blood cells, this is why people who have lung disease or smoke get out of breath easily
this could be cause by a condition called fibrosis where the alveoli walls scar and thicken making a larger diffusion distance. also causing the walls to lose elasticity. this could be cause by a condition called fibrosis where the alveoli walls scar and thicken making a larger diffusion distance. also causing the walls to lose elasticity. this could be cause by a condition called fibrosis where the alveoli walls scar and thicken making a larger diffusion distance. also causing the walls to lose elasticity.
The Alveoli itself can not be 'lost', but it is possible to lose their function. Alveoli can lose their ability to exchange Oxygen and Carbon Dioxide with Blood. They can lose their elasticity and eventually rupture. Once they have ruptured it is impossible to reverse, and the damage is permanent.
EmphysemaA disease whereby the elastin in the walls of the alveoli is broken down by an imbalance between the production of neutrophil elastase (elevated by cigarette smoke) and alpha-1-antitrypsin (the activity varies due to genetics or reaction of a critical methionine residue with toxins including cigarette smoke).The resulting loss of elasticity in the lungs leads to prolonged times for exhalation, which occurs through passive recoil of the expanded lung.This leads to a smaller volume of gas exchanged per breath.
Emphysema mainly affects the alveoli within the lungs. Over time, the alveoli lose their elasticity and become damaged, causing difficulties in breathing and decreased oxygen exchange. This leads to symptoms like shortness of breath and coughing.
because elasticity of alveoli is diminished in patient with COPD therefore administering more than 4liters/minute will collapse alveoli and patient may die.
Type II alveolar cells in the lungs secrete surfactant, which is a specialized fluid that lowers surface tension in the alveoli. This reduces the tendency for the alveoli to collapse during exhalation and helps maintain the elasticity of the lungs for efficient gas exchange.
