The respiratory system (called also respiratory apparatus, ventilatory system) is a biological system consisting of specific organs and structures used for the process of respiration in an organism. The respiratory system is involved in the intake and exchange of oxygen and carbon dioxide between an organism and the environment.

In the environmental context, 'respiratory' refers to the effects of environmental pollutants on the respiratory system, which includes the lungs, airways, and other structures involved in breathing. Exposure to environmental pollutants can cause a range of respiratory problems, including irritation, inflammation, and damage to the lungs and airways. Here are some examples of respiratory issues related to environmental pollutants:

1. Asthma: Asthma is a chronic respiratory disease that is often triggered by exposure to environmental irritants such as air pollution, pollen, and dust. Asthma can cause inflammation and narrowing of the airways, making it difficult to breathe.

2. Chronic Obstructive Pulmonary Disease (COPD): COPD is a group of lung diseases that cause breathing difficulties and can lead to chronic bronchitis and emphysema. Exposure to tobacco smoke, air pollution, and other environmental pollutants can increase the risk of developing COPD.

3. Respiratory infections: Exposure to environmental pollutants can weaken the immune system and increase the risk of respiratory infections, such as pneumonia and bronchitis.

4. Lung cancer: Exposure to environmental carcinogens, such as asbestos and air pollution, can increase the risk of lung cancer. The carcinogens can damage the lung tissue and trigger mutations in the DNA of lung cells, which can lead to cancer.

5. Silicosis: Silicosis is a lung disease caused by exposure to silica dust, which can be found in industries such as mining, construction, and agriculture. Silicosis can cause inflammation and scarring of the lungs, making it difficult to breathe.

6. Black lung disease: Black lung disease, also known as coal workers' pneumoconiosis, is a lung disease caused by exposure to coal dust. It can cause inflammation and scarring of the lungs, leading to breathing difficulties.

Overall, respiratory problems related to environmental pollutants can have a significant impact on public health. Reducing exposure to environmental pollutants through proper regulation and control measures can help prevent these respiratory issues and improve overall public health.
