In order for us to understand how pollution affects our body, we must understand exactly what it is. The pollution that harms our respiratory system is known as particulate, they are the small solid particles that we can see through the ray of sunlight. Particulate are products of incomplete combustion in engines, an example would be automobile engines, and others particulate are road dust, and wood smokes. Simply taking a breath causes these particulate to our bodies. The damage begins when the particulates are inhaled into the small air sacs of our lungs called alveoli.

The particulate causes the inflation of the alveoli, which causes the body to produce agents in the blood that increase clotting ability, and leads to the decreased functional of the cardiovascular system, resulting in diseases. In the blood, carbon monoxide (CO) interferes with the supplying of oxygen to the tissues and organs, this included the brain and heart. If exposure to particulate continued, it will damage the lungs and increase a person's chances of developing conditions such as chronic bronchitis and emphysema. Among the most dangerous pollution to our health are carbon monoxide (CO), nitrogen oxides (NO), sulfur dioxide (SO), and ozone. Incomplete burning of fossil fuels, cars, trucks, gas furnaces and stoves, and some industrial processes produces these poisonous gases.
