Interstitial Lung Disease Life Expectancy, A Brief And Critical Analysis


Interstitial lung disease life expectancy, Lungs are the organs of the body which are concerned with breathing. Breathing is the method used by the body to take in the air and extract oxygen from it. This oxygen is essential for life.

Interstitial Lung Disease Life Expectancy What do the lungs do?

Interstitial Lung Disease Life Expectancy

The lungs form part of the respiratory system and their function is essential to sustain life and to protect from ILD. They make the breathing in of oxygen from the air possible, as well as the exhaling of carbon dioxide.

 Lungs are the organs of the body which are concerned with breathing. Breathing is the method used by the body to take in the air and extract oxygen from it. This oxygen is essential for life.

It passes from the lungs into the bloodstream, where millions of red blood cells hold the oxygen and carry it to all the tissues of the body. Without oxygen, the tissues would die.

The tissues use oxygen to release energy for their various functions. Carbon dioxide produced by these chemical reactions enters the bloodstream and would be harmful if it were allowed to accumulate in the body. The lungs also have the task of extracting excess carbon dioxide from the blood and allowing it to be expelled when the air is breathed out of the chest.

interstitial lung disease causes

There are two lungs in the chest cavity, set around the heart and the main blood vessels which lead away from, and into, the heart. The right lung is slightly bigger than the left. From the back of the throat, the trachea (tubular windpipe) goes down inside the neck to reach the lungs. At its lower end, it splits into two branches, known as the right and left bronchus, which enter the lungs.

How To Protect lungs From Interstitial Lung Disease Life Expectancy?

The lungs do not themselves create breathing movements. Air is drawn into them or expelled from them by the actions of some of the chest muscles. These are the muscles between each rib and its neighbor and also one dome-shaped muscle called the diaphragm, which stretches across the base of the chest space, separating it from the abdominal cavity below.

When breathing in (inspiration), the rib muscles contract, causing the chest wall to move up and outwards. At the same time, the diaphragm contracts and flattens its dome downwards. These muscle actions increase the space inside the chest. The resulting pressure change draws air through the windpipe into the lungs, which expand.

When breathing out (expiration), the rib muscles relax at the same time as the diaphragm, whose dome bulges up again. The chest walls subside and the chest resumes its former shape. Consequently, the volume of the chest space decreases. The natural elasticity of the lungs causes them to decrease in size, and therefore expel their contents through the windpipe into the atmosphere.

What is the average breathing rate?

The normal rate of breathing for an adult is about 12 times a minute. At complete rest, such as when sleeping, the rate may decrease to about nine or ten times a minute. During any vigorous activity which makes the heart beat faster, such as running, the body’s need for oxygen is high, and the breathing rate could rise to about 20 times a minute or more. It is not only physical activity which alters the breathing rate; experiencing strong emotions can cause the breathing rate to increase.

What happens inside the lungs?

After entering the lung, each bronchus divides many times, with the ‘tubes becoming thinner and thinner at every division.

Finally, these microscopically small tubes (bronchioles) lead into clusters of minute air sacs (alveoli).

These sacs have extremely thin walls and are covered with a dense network of fine blood vessels with walls just as thin. From the air inside the sacs, oxygen passes through both walls and enters the bloodstream.

At the same time, any excess carbon dioxide in the blood moves through the blood vessel walls into the air sacs and will be breathed out.

How do the lungs protect the body and Interstitial Lung Disease Life Expectancy?

The air we breathe is not always as clear and pure as it should be. The trachea and each bronchus are lined with quantities of tiny hair-like threads (cilia) which trap and hold back solid particles in smoke or very fine granules of dust to prevent them entering the lungs.

The sticky mucus produced by some of the cells lining the walls of the airways also helps in this filtering process by trapping foreign particles.

Smoking can damage the delicate, hair-like cilia of the air tubes which filter

out any irritating or foreign particles we breathe in. If damaged, the protection they provide to the lungs is reduced and the rate of  ILD increased.
