    Emphysema is a long-term lung disease, which occurs when alveolar walls are destroyed, which causes the capillary blood vessels to be destroyed as well. Alveoli are air sacs in the lung. Emphysema not only causes trouble breathing, chronic coughs may be experienced as well. Emphysema are caused when the walls of air sacs are destroyed due to smoking. The air sacs are destroyed when the smoke affects the white blood cells and then cause the destruction of lung tissue. Once the walls of the air sacs break there is less surface area for gas exchange and breathing is hard. People with emphysema can usually only walk 2 or 3 meters before becoming breathless! More specifically, smoking triggers inflammatory cells inside the lung. The inflammation causes the bronchioles to swell; proteases (type of enzymes) to be activated, which attacks or destroys the alveolar wall structures. The air sacs in the lungs are not able to fill the sacs with fresh air, which affects the oxygen supply for the body.

    {Bronchitis.jpg} http://www.webmd.com/lung/understanding-bronchitis-basics
    If you continue to smoke, the damage may prevent the cilia from functioning normally, which increases the chances of developing chronic bronchitis or long-term bronchitis. Heavy smokers would have an inflamed membrane and cilia that stops working. The mucus is clogged, which the lungs become vulnerable to bacterial infections. These infections can permanently destroy the lungs’ airways overtime. The condition is called COPD or chronic obstructive pulmonary disease.

    How does smoking cause bronchitis?
    When cilia are destroyed more mucus is able to stay in the respiratory system. The mucus might contain microbes and dust which are able to move down into the lungs. The microbes and dust cause the person to cough a lot which inflames t3he lining of the bronchi.

    thoracic/rib cage.
    The nose and mouth is where air enters the body, with the nasal cavity behind the protruding nose. In the nostrils, the dense network of hairs filter particles in the air. The air then meets the walls of the nasal cavity, which is covered in a mucous membrane with a rich blood supply. Once air comes in contact with the mucous membrane, remaining air particles get stuck to it because the mucous membrane warms and moistens the air, allowing air to pass back and down, into the pharynx.
    The rood of the mouth/buccal cavity is formed by a hard and soft palate, ending bear the top of the lips and at the sides of the muscles by the cheek; the tongue forms and fills the floor of the mouth. It is because of muscular soft palate that hangs at the back of the hard palate that separates the mouth and the pharynx - the soft palate moves backwards to block the nasal cavity so that food cannot enter and block the airway.
    ...
    the larynx.
    The larynx can also be called the voice box, which is positioned in the neck behind the hyoid bone, connecting to the trachea. It specialises in voice production, and allows air into and out of the lungs. There are 5 cartilages that make it up: thyroid, cricoid, epiglottis, and 2 arytenoid cartilages. The largest, the thyroid cartilage, is commonly known as the Adam's apple, and protects the vocal chords.
    ...
    the stomach.
    The structure of the left and right principal bronchi is that it is similar to the trachea: incomplete rings of cartilage united by fibroblastic membrane. They travel in separate directions, enter the lung through the hilum, then divide into smaller lobar bronchi. The lobar bronchus branches then spread and divide into smaller segmental bronchi in each of the segments of the lungs. The combination of the divisions of the bronchi create the bronchial tree.
    The "last branches" of the bronchial tree are called the bronchioles, and are composed completely of a fibroblastic membrane and smooth muscle. The smallest of these bronchioles branch to form multiple alveolar ducts.
    The ducts lead into alveoli sacs, where the individual alveoli where gas exchange takes place. Hundred of millions of alveoli sacs make up the large surface area for the diffusion of gases. The alveoli, being only 1 cell wide, have very tiny and thin walls that surround the rich blood supply in the air sacs. There are capillaries that surround the alveoli, which means that the barrier for gasses to diffuse through is 2 cells thick, in order for it to get access to the blood stream. The inside of the alveoli wall is moist, which allows oxygen from the air we breath to dissolve on it, and because of the rich phospholipids and proteins, when we breath out, the alveoli don't collapse. Inside the alveoli, bacteria can be killed once it has entered the lungs and has been trapped on the moist walls.
