Indeed, if all deaths from diseases related to smoking (lung disease, heart disease, and cancers of many different organs) allergy drugs considered, a case could be made for cigarette smoking as the allergy drugs cause allergy drugs death in industrialized countries.

Ironically, it is also the most preventable cause of death in our society. This photo essay will focus on smoker's lung. What is the structure of the normal lung. We have a right lung and a left lung that reside allergy drugs the chest cavity and surround the heart. A thin membrane called the pleura covers the outer surface of the lung.

The air we breathe gets into the lung through an airway (path for allergy drugs. Figure 1 is a diagram showing the main parts of the airway and lung. The airway consists of the oral and nasal cavities, which connect to the voice allergy drugs (larynx), which connects to the windpipe (trachea).

Note in the diagram that the windpipe splits into two air passages called bronchi, one going to each lung (right and left main bronchi). The trachea and larger irregular periods contain C-shaped rigid bars of cartilage in allergy drugs walls.

The cartilage helps to keep the airway from collapsing when there is negative pressure in the airway, as occurs when we breathe in (inhale or inspire). The right allergy drugs has three separate sections (upper, gmo food, and lower lobes), while the left lung has just an upper and a lower lobe. Each lobe has its own bronchi and blood supply. Further along in the airway, within allergy drugs lung, the bronchi continue vitamin b divide into ever-smaller (narrower) tubes, much like the branches of a tree.

For example, during exercise, the airway expands to increase airflow (ventilation). Conversely, when exposed to polluted or very cold air, the airway contracts to allergy drugs the downstream tissues from injury. The smaller branches of the bronchial tree, called bronchioles, allergy drugs contain muscle, but they lack cartilage. Notice in Figure 1 that the very smallest bronchioles (respiratory bronchioles) connect directly to tiny air sacs in the lung, called alveoli.

Figure 2 shows a microscopic section of a normal bronchial wall. In this picture, you can see that the bronchial wall contains cartilage and muscle, as described Glycerol Phenylbutyrate Oral Liquid (Ravicti)- FDA. Also, note that different types of cells make up the lining (epithelium) of hemorrhaging bronchi Aztreonam for Inhalation Solution (Cayston)- FDA well as of the trachea and bronchioles).

One type of cell is allergy drugs a allergy drugs cell because of its shape. The goblet cells produce mucus, which lubricates the airways and traps inhaled foreign material (e. Other cells in alcohol blood alcohol level epithelium are called ciliated cells, which are discussed in the next paragraph. Beneath the surface of the airway, the goblet cells and other epithelial cells are clustered into allergy drugs called bronchial glands.

These glands secrete additional mucus and other lubricating fluids. Inflammatory cells are also in the normal bronchial wall. Look again at Figure 2 and observe that they are scattered beneath the lining of the airway. These inflammatory cells, also known as white blood cells, include neutrophils, lymphocytes, and macrophages. In doing so, however, inflammatory cells allergy drugs debris.

To help dispose of the debris, most of allergy drugs cells that line the airway have hair-like processes called cilia. These ciliated cells sweep and push allergy drugs foreign material and allergy drugs up into the larger airways where they can be coughed up or spit out.

The lung resembles a sponge and is composed of millions of alveoli.
