Lungs are the most delicate organs of the human body and are made up of tiny passage ways and air chambers which help in breathing. When humans breathe in they inhale fresh air rich in oxygen which is a life sustaining element and when they exhale carbon dioxide is expelled from the body. When oxygen reaches the tiny chambers of the lungs it is sent to the red blood cells to replace carbon dioxide. To breathe properly the passage ways in the lungs should be free from any kind of sediments which can block the ways thus hampering the normal breathing process. Inside the lungs there are numerous tiny hair-like stalks known as cilia which aid to keep the lungs free from sediments and impurities thus preventing clogging. When a person smokes, harmful chemicals accumulate in the lungs thus causing a blockage in the passage ways. If a person is a heavy smoker then the cilia fails to do its function properly. Heavy smoking often causes damage to the delicate cilia thus severely hampering the cleaning process. This result in nasty coughing, an effort made by the body to clean the lungs. In order to stop the person from excessive coughing a simple combination of vitamins and food supplements can be taken to clean and prevent lungs from blockage caused by the accumulation of toxins.
