Which of the following part of human body is severely affected by air pollution? 

The correct answer is Lungs.

Explanation-

Air pollution has a significant impact on our lungs. Here's how:

• Inflammatory reactions: When we breathe in polluted air, small particles and harmful gases can reach deep into our lungs, causing inflammation. Over time, exposure to air pollution can lead to chronic respiratory diseases, such as asthma and chronic obstructive pulmonary disease (COPD).
• Respiratory Infections: The small toxic particles found in polluted air can also enhance the risks of bacterial and viral infections in the lungs, which can lead to pneumonia or bronchitis.
• Aggravation of existing conditions: Air pollution can worsen pre-existing conditions, such as asthma or lung disease, making the symptoms more severe.
• Lung cancer: Long-term exposure to certain air pollutants, like fine particles and toxic gases, has been directly linked with lung cancer. Many of these harmful substances in polluted air are known carcinogens.
• Reduced lung function: Chronic exposure to air pollution can cause significant reductions in lung function, leading to difficulties in breathing, fatigue, and other related health issues.
• Allergies: Air pollution contributes to higher concentrations of allergens in the air, which can trigger allergic reactions that impact the lungs, such as allergic asthma.

Conclusion- Lungs are severely affected by air pollution
