How does contaminated air reaches the heart?

Contaminated air can reach the heart through the respiratory system when pollutants, such as particulate matter and toxic gases, are inhaled. These harmful substances enter the lungs, where they can penetrate into the bloodstream and trigger inflammatory responses. This can lead to the development of cardiovascular diseases by causing arterial damage, increasing blood pressure, and promoting plaque buildup in the arteries. Ultimately, the heart is affected as it works harder to pump blood through narrowed or damaged vessels.
