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 oesophagus 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

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 oesophagus 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.

Tobacco first attacks the trachea and cilia

With one drag on a cigarette over 4000 chemicals are released into almost every system of your body. Nicotine is only one of the many chemicals that are working against your entire body. When the chemicals enter the mouth and trachea, it irritates them and leaves minor chemical burns as it travels down. This is the reason many people complain about sore throats and pain when they first began smoking. Many of these chemical compounds have cancer-causing properties, as well as their harsh chemical make ups. Given enough burns on the trachea and voice box, it will scar them for life, giving the smoker the "smoker's voice" and cancer of the throat as these chemicals slowly burn a path. When this chemical cocktail spills into your lungs as a breath of air, it immediately attacks the cilia. These little hairs are burnt and stunted, and are no longer able to do their job.

Destruction of the lung

With the cilia unable to carry out the toxins, the full 4000 chemicals enter directly into the lungs. These chemicals immediately attack everything they come into contact with. With the vital cells damaged and dying, cancer fills in the holes. The alveoli, being also burnt and scarred, looses the ability to take in air and move air through the body. This is classic emphysema. The longer the chemicals are introduced, the more the lung will be eaten and burnt away. Finally, the lung looks like it has been chemically burnt, as it has been.
