Summary:
A new report shows that living close to major roads may impact kidney function. Over 1100 stroke patients were tested to find their glomerular filtration rate, or GFR, by measuring a metabolic by product called serum creatinine. The results show that those who live 50 meters away from a major road had a much lower GFR compared to those who lived 1000 meters away from a major road. The GFR can help indicate how efficiently the kidneys are working. Therefore, a lower GFR suggests that the kidneys are not working as efficiently compared to a higher GFR. The chances of cardiovascular death go up by approximately 4% due to living within 50 meters of a major road compared to living 1000 meters away from a major road. The risk increase, as well as the lowering of the GFR, are being associated to the air pollution caused by traffic. Exposure to a major roadway may affect the kidney, as it is highly sensitive to the build up of plaque.

Connection:
We have been studying the human body and the circulatory system. This article relates to the circulatory system because plaque build up can damage the kidneys. Additionally, we have also learned about various cardiovascular diseases which may cause death. In addition to the circulatory system, the article also talks about various parts of the excretory system which shows how various systems in our bodies work together and are intertwined.
