Circulatory System:

• Heart
• Blood

Noise pollution affects both our blood and heart in different ways. It affects our heart by giving us heart disease, this speeds up the aging process of hearts causing a high rate of of myocardial infraction. In other words this is known as a heart attack. Long term exposure to noise pollution can lead to high blood pressure, especially in the night because the rate is a lot higher. E.g. Moving cars and people shouting in cities.
