Smoking and Lung Cancer

Knowingly what harm does smoking possess to our body people still smoke every day and some of them are so addicted to smoking that they smoke half a dozen cigarettes in a day without any hesitation.  Smoking destroys the lungs at the tissue level that decreases the lung space which in turn results in transporting less oxygen to the body.  the inhalation process of the human body is quite simple, as it begins when as a person inhales the air that reaches the nasal cavity which is followed by the pharynx the larynx, and from the windpipe, it reaches bronchi which is gain passes on to the bronchioles and the air finally reaches the air sacs where the actual exchange of gases takes place.

The alveoli sac in the body is the smallest sac where the actual exchange of oxygen and carbon dioxide takes place. The air we inhale it passes through the above-mentioned passage and enters the alveoli sac, now to understand the transportation of oxygen to the body we have to take the heart into consideration as well. As both heart and lungs work together in complete synchronization, in order to provide oxygenated blood to the entire body maintaining its function. In the human heart, the blood enters the heart twice because of which is called double circulation as well. Firstly, the carbon dioxide-rich blood from the entire body reaches the heart through veins from there it reaches the lungs through pulmonary arteries where the actual exchange of gases takes place. In the alveoli sac, the carbon dioxide is absorbed and the oxygen is released in the blood which is sent o the pulmonary veins from where it reaches the heart again, hence, called double circulation. From the heart through the aorta and other capillaries the oxygenated blood reaches the entire body.

The above process of purification of blood was explained to how interconnected lungs and heart are and how smoking can affect the overall functioning of the body. People who smoke their lungs are damaged as the alveoli sacs are damaged slowly and slowly, so, there is less part of the lungs that helps in the exchange of gases and consequently, it causes various lung diseases and heart diseases.  The harmful chemicals, smoke, and toxins from the cigarette create tar that accumulates in the lungs that block the passage for air exchange and enters the blood and can cause any type of damage depending upon person to person.
