How Does Smoking Affect the Respiratory System?
The Respiratory system Looking at the respiratory system is a look at one of the most vital systems of our body. Depriving a person of this system will kill them quicker than most. The respiratory system is comprised of three parts: intake (mouth and nose), travel (trachea), and factory (lungs). We take in air from our mouth or nose. The nose is our predominate way of taking in air. It has little hairs that filter many of the items that can hurt us. Once we take in the air, a flap closes off the esophagus to make sure there is no air in the stomach and there is no liquid in the lungs. Then the air arrives in the lungs where there are cilia, another filtering device. These tendrils move harmful air and pollutants out of the lungs. The air passes down through the lungs to the alveoli which process our air, and allows us to breath Tobacco first attacks the trachea and cilia jQuery(document).ready(function(){ jQuery(‘#jsArticleStep1 span.image a:first’).attr(‘href’,’http://i.ehow.com/image
