Question

Answer

Panacinar emphysema(panlobular emphysema): is an abnormal weakening & enlargement of all alveoli distal to the terminal bronchioles, including respiratory bronchioles, alveolar ducts, alveolar sacs & alveoli the entire acinus is affected by dilation & destruction.

Answer

Answer

EMPHYSEMA IT IS RELATED TO CHRONIC INFECTION IN OUR II MANY IN PULMONARY PART IT IS IN FACT WHEN WE TAKE SNORTING SUBSTANCE LIKE SMOKING OR IN TAKING POLLUTED AIR OR EVEN THE WORKERS WHO ARE WORKED IN A UNDERGROUND HEAGY PROMINENT AREAS WHERE TOO MUCH DARK AND EVEN THE THE UNDERGROUND CONSTRUCTIONS THEY ARE MAYBE RELATED TO COAL OR EVEN DIGGING OF HISTORICAL SUBSTANCES SO.

WE CAN SIMPLY SAY THAT EMPHYSEMA IT IS RELATED TO CHRONIC INFECTION IN THE THE PULMONARY PART IT FIRSTLY AFFECT OUR LUNGS AND THEN FURTHER TO OUR DAMAGE THE LUNGS.

Answer

Emphysema is a pulmonary disease characterized by the destruction and enlargement of the air sacs (alveoli) in the lungs. It is a chronic obstructive pulmonary disease (COPD) that primarily affects the respiratory system.

Cause:
- Emphysema is most commonly caused by long-term exposure to irritants, particularly cigarette smoke.
- Other factors such as exposure to air pollution, occupational dust and chemicals, and genetic factors can also contribute to the development of emphysema.

Symptoms:
- The main symptoms of emphysema include shortness of breath, coughing, wheezing, and chest tightness.
- As the disease progresses, individuals may experience difficulty breathing even at rest and develop a barrel-shaped chest due to the increased lung volume.

Pathophysiology:
- Emphysema is primarily a result of damage to the alveoli, which are responsible for gas exchange in the lungs.
- Prolonged exposure to irritants leads to inflammation and destruction of the walls of the alveoli, causing them to lose their elasticity.
- This results in the collapse of the small airways and a decrease in the surface area available for oxygen exchange, leading to impaired lung function.

Effect on the Respiratory System:
- Emphysema causes a significant reduction in the lung's ability to take in oxygen and remove carbon dioxide from the body.
- The damaged alveoli are unable to effectively exchange gases, leading to hypoxemia (low oxygen levels in the blood) and hypercapnia (high carbon dioxide levels in the blood).
- The increased work of breathing and decreased lung capacity lead to progressive breathlessness and decreased exercise tolerance.

Treatment:
- While there is no cure for emphysema, management focuses on relieving symptoms, slowing disease progression, and improving quality of life.
- Treatment options include lifestyle modifications (smoking cessation, avoiding respiratory irritants), pulmonary rehabilitation, medications (bronchodilators, corticosteroids), and in severe cases, surgical interventions such as lung volume reduction surgery or lung transplantation.

Conclusion:
- Emphysema is a pulmonary disease that primarily affects the respiratory system. It is characterized by the destruction and enlargement of the alveoli in the lungs, leading to impaired lung function and symptoms such as shortness of breath. Understanding the causes, symptoms, and pathophysiology of emphysema is crucial for its proper diagnosis and management.
