What is the main function of the respiratory system?

• To regulate body temperature through sweating.

• To facilitate gas exchange (oxygen and carbon dioxide) between the body and the environment.

• To produce hormones that control metabolism.

• To filter and purify blood before it circulates.

How does air pollution affect our health?

• Air pollution has no effect on health whatsoever.

• Air pollution negatively impacts health by causing respiratory and cardiovascular diseases, and increasing the risk of chronic health issues.

• Air pollution improves overall health and well-being.

• Air pollution only affects the environment, not human health.

What are some sources of air pollution?

• Solar energy

• Wind patterns

• Ocean currents

• Industrial emissions, vehicle exhaust, burning fossil fuels, agricultural activities, wildfires, volcanic eruptions

What is the Air Quality Health Index?

• A scale used to determine humidity levels in the air.

• A method to measure temperature variations in the atmosphere.

• A tool for predicting weather patterns based on air pressure.

• The Air Quality Health Index (AQHI) is a numerical scale that indicates the health risks associated with air quality based on pollutant concentrations.
