Emphysema is a form of Chronic Obstructive Pulmonary Disease (COPD), a condition that affects the lungs, making it difficult for a person to breath.
The part of the lungs that are affected are the alveoli.
The alveoli start to explode, which causes big air spaces to form.
Because of the large air spaces, the surface area is smaller and so is the amount of oxygen received.
The respiratory system is responsible for the gas exchange that provides the body with oxygen (O2) and eliminates Carbon Dioxide (CO2) from the body. This exchange of gases happens through a process called diffusion, where O2 diffuses into the capillaries, and CO2 diffuses into the lungs. This point of diffusion is the alveoli, located at the end of bronchioles.
This process of diffusion relies on moist, thin, large surface areas.

The result of this is that air becomes trapped in the alveoli, and prevents O2 rich air from entering the lungs.
Due to the inability of the lungs to exchange gases and air, those suffering from emphysema experience a chronic cough, difficulty breathing, and an increased risk of lung infections.
The main causes of this damage to the alveoli are air pollutants and tobacco, and particles of chemicals and dust.
In this image, you can see the damage present in the alveoli. Here the alveoli walls have been damaged by emphysema, and as a result, the surface area of the lungs is reduced. The alveoli become one large sack rather than a collection of tiny air sacs.
Above is an actual image of a male rat’s lung with emphysema. This image demonstrates the decreased surface area present within a lung with emphysema.
There are several ways in which emphysema can be diagnosed. Some of these include chest X-rays, computerized tomography—a collection of X-ray images, and blood
The presence of fluid in the alveolar space could potentially cause the lung capacity to be effected as well.
heart problems the damaged of alveoli lead to decrease the amount of oxygen in bloodstream because of that the heat will pump strongly to allow blood to reach the lungs. Emphysema also may increase the pressure on blood vessels that connect the lungs and heart, in addition, it can affect a section, which response for contractile and relaxing of the heart, called cor pulmonale. Moreover, pneumothorax, which called also collapsed lung. At this case,, Lager holes, or giant bullae, it is form when empty spaces is develop. Large holes may be as big as half of the lungs. These giant bullae may burst , as a result, the lung deflation will

As a result of emphysema there is a significant loss of alveolar attachments, which contributes to peripheral airway collapse. There are two major types of emphysema according to the distribution within the acinus and they are; (i) centrolobular emphysema which involves dilatation and destruction of the respiratory bronchioles; and (ii) panlobular emphysema which involves destruction of the whole of the acinus. According to theory, centrolobular is the most common type of emphysema in COPD and is more prominent in the upper zones, while panlobular predominates in patients with alpha-1 antitrypsin deficiency and is more prominent in the lower zones. In relation to patients D.Z. with emphysema, the walls between the tiny air sacs in the lungs are damaged due to long-term cigarette smoking effect on his lungs as evidenced by patient c/o difficulty breathing at rest and productive cough with thick yellow-green sputum r/t a
Emphysema affects the parenchyma of the lung through destruction of the alveolar walls, leading to permanent enlargement of air spaces distal to the
A person with COPD has damaged alveoli and bronchi. This means they have weakened and ruptured air sacs that are unable to efficiently perform the exchange of gases (oxygen and carbon dioxide). As the disease progresses, damage increases to the air sacs to the point of a person feeling breathless even when
Many elderly people in the U.S. have the medical condition of emphysema, a respiratory disease. It affects millions of Americans each year. Read below for information on the disease, courtesy of expert home health care provider Champion Home Health Care.
Emphysema is the third leading cause of death in the United States. It is a chronic, progressive disease that affects the morbidity and mortality of life. Like many chronic diseases, diagnosis is affected by numerous variables. There is no cure; however, there are effective treatment methods which can slow the progression of the disease and allow for a normal life. In short, the diagnosis of emphysema is not a death sentence. Rather, it is an illness that should prompt a person diagnosed with it to take the lead in the management of the disease. The primary risk factor for this disease that can be controlled is the smoking of cigarettes. Smoking cessation is the most beneficial first step to preventing or stopping the development or progression
The Lung Pulmonary Function Test measures the amount of air that is inhaled and exhaled with each breath, it also measures the amount of oxygen that blood receives from the lungs. A Chest X-Ray tests the lungs for emphysema, which can be further diagnosed as COPD. A CT Scan can also be used in order to detect emphysema and determine if you’re eligible for surgery. This scan can also show different types of lung cancer that may have developed. The Arterial Blood Gas Analysis is another form of testing that can be used to diagnosis this disease. This test measures how well your lungs bring in oxygen and release carbon dioxide. In order to check for an Alpha-1 deficiency, a Laboratory Test can be performed. Although there are many forms of diagnosing this disease, there is no actual cure. However, there are many ways to reduce the symptoms which include medicines that can help with specific symptoms, an increase of physical activity, prevention of flare-ups, quitting smoking and inhalation of other harmful substances, and pulmonary
Emphysema is common, yet serious condition that is a type of chronic obstructive pulmonary disease. It is so serious because it can enlarge and eventually destroy air spaces within the lungs. This disease effects millions of people in the United States, and is the third leading cause in the United States. Smoking is the leading cause of this condition. Understanding how COPD works, it helps to know how the lungs work as well. When you inhale air, that air is sent down your windpipe, or trachea, into tubes called bronchi. These bronchial tubes then branch into the lungs by getting smaller, thinner and by the thousands, these are
The bronchi and bronchiole tubes are loosely wrapped with muscle. During regular breathing, the muscles around these airways are relaxed (5). This allows air to flow freely through these passageways to the alveoli. However, during an asthma attack, air has trouble reaching the alveoli, which prevents the body from receiving oxygen. This is because the airways become smaller. Firstly, the muscles around the airways spasm and contract. This then causes inflammation of the bronchioles and bronchi themselves, which causes a mucus to be produced.
Emphysema is a condition of the lungs that involves the over-inflation of the air sacs, otherwise known as the alveoli. Normal functioning of the alveoli helps breathing in normal respiration. Unlike other lung diseases this one can be inherited. This is a disease that can affect people of all ages and genders. In 1994, the number of males with emphysema outnumbered the females by fifty four percent. However, in the two years that followed the difference between males and females decreased by ten percent.
Within the alveoli, the oxygen is transferred to the blood whilst simultaneously collecting waste carbon dioxide for excretion as we breath out. This transference is known as diffusion and is linked to the cardiovascular system.
Emphysema Emphysema is a condition in which there is over-inflation of structures in the lungs known as alveoli or air sacs. This over-inflation results from a breakdown of the walls of the alveoli, which causes a decrease in respiratory function (the way the lungs work) and often, breathlessness. Early symptoms of emphysema include shortness of breath and cough. Emphysema and chronic bronchitis together comprise chronic obstructive pulmonary disease (COPD).
The simple act of breathing is often taken for granted. As an automated function sustaining life, most of us do not have to think about the act of breathing. However, for many others, respiratory diseases make this simple act thought consuming. Emphysema is one such disease taking away the ease, but instead inflicting labored breathing and a hope for a cure.
