  Bronchus - Wikipedia, the free encyclopedia
There is hyaline cartilage present in the bronchi, present as irregular rings in the larger bronchi (and not as regular as in the trachea), and as small plates and islands in the smaller bronchi.
Bronchitis is viral or bacterial infection of the bronchi.
Asthma is hyperreactivity of the bronchi with an inflammatory component, often in response to allergens.

 Gray, Henry. 1918. Anatomy of the Human Body. Page 1100
The bronchial arteries supply blood for the nutrition of the lung; they are derived from the thoracic aorta or from the upper aortic intercostal arteries, and, accompanying the bronchial tubes, are distributed to the bronchial glands and upon the walls of the larger bronchial tubes and pulmonary vessels.
Those supplying the bronchial tubes form a capillary plexus in the muscular coat, from which branches are given off to form a second plexus in the mucous coat; this plexus communicates with small venous trunks that empty into the pulmonary veins.
The bronchial vein is formed at the root of the lung, receiving superficial and deep veins corresponding to branches of the bronchial artery.

One of the first effects of inflammation upon the bronchial mucous membrane is to cause some degree of swelling, which, together with the presence of a tough secretion closely adhering to it, tends to diminish the calibre of the tubes.
Occasionally a branch of a bronchial tube becomes plugged up with secretion, so that the area of the lung to which this branch conducts ceases to be inflated on inspiration.
In additon to the remedies already alluded to, stimulants are called for from the first; and should the cough be ineffectual in relieving the bronchial tubes, the administration of an emetic dose of sulphate of zinc may produce a good effect.

 University of Miami School of Medicine - Glossary - Asthma
Asthma is a chronic inflammation of the bronchial tubes (airways) that causes swelling and narrowing (constriction) of the airways.
Bronchial tubes that are chronically inflamed may become overly sensitive to allergens (specific triggers) or irritants (non-specific triggers).
Normal bronchial tubes allow rapid passage of air in and out of the lungs to ensure that the levels of O2 and CO2 remain constant in the blood stream.

 Bronchiectasis | Principal Health News
Bronchiectasis is a condition in which an area of the bronchial tubes is permanently and abnormally widened (dilated), with accompanying infection.
The bronchial tubes are the networks of branching tubes which deliver air to the tiny sacs of the lungs (alveoli).
When bleeding occurs from irritated bronchial tubes and overgrown bronchial blood vessels, surgery may be required either to remove an area of the bronchial tube, or to inject the bleeding blood vessel with a material to stop the bleeding.

 [No title]
Bronchial asthma is a chronic (long term) disease affecting the bronchial tubes (bronchi, breathing tubes, or airways) of the lungs.
This constriction is caused by bronchial tube muscle spasms and airway narrowing due to inflammation, which leads to swelling of the lining and increased mucous secretion.
Partial or total reversibility of bronchial tube spasm is a primary characteristic of bronchial asthma early in the course of the disease.

 What is Asthma
This disease causes the bronchial tubes to be overly sensitive to many different things; when exposed to these things, the bronchial tubes of persons with asthma narrow, making it difficult for air to pass freely in and out of the lungs.
Asthma is a chronic disease in that the tendency of the bronchial tubes to narrow abnormally in response to exposure to certain triggers is present day and night, day after day for months and years at a time and sometimes lifelong.
One example is seasonal variation in hyper-responsiveness of the bronchial tubes in persons with pollen allergy: during pollen season they become more sensitive to all of their triggers of asthma (not just to pollen); out of pollen season they gradually become less sensitive again.

Bronchial asthma is usually a episodic disease affecting the bronchial tubes (bronchi, breathing tubes or airways) of the lungs.
One of the major underlying causes of bronchial asthma is related to the phenomena of mast cell chemical mediator release.
Finally, obstruction to the inner passageway of the bronchial tube may result from the thick, sticky mucus and mucous plugs that are characteristically produced during an asthmatic attack.

 Acute Bronchitis
Acute bronchitis is an infection of the bronchial tree.
The bronchial (say: "brawn-kee-ull") tree is made up of the tubes that carry air into your lungs.
This is because your bronchial tree is already inflamed and damaged as the toxic smoke fumes paralyze and kill the cilia that line the bronchial tree and are important in helping clear the excess mucous from the bronchial tubes.

 British Lung Foundation - Bronchiectasis
Air is carried into the lungs through a series of branching tubes- the 'bronchi'.
When the bronchial tubes get damaged, they can no longer clean themselves and the mucus accumulates in the tubes, spilling over to adjacent tubes.
If live bacteria persist in the tubes, inflammation occurs and white blood cells are recruited from the blood to kill the bacteria.

 Bronchitis   (Site not responding. Last check: 2007-10-19)
Bronchitis is an acute inflammation of the respiratory tract, particularly the bronchi (often referred to as the tracheobronchial tree).
Chronic Bronchitis suggests a weakness of the bronchial tree or chronic infection in the bronchi, sinuses, lungs, allergies and in children, enlarged tonsils or adenoids may predispose to recurrent bronchitis.
As cells that line the bronchial passages die they are shed into the bronchial tubes along with a watery to thick sticky mucous which is generally produced in response to the irritation.

 Blair County Respiratory Disease Society
When the bronchi are inflamed and/or infected, less air is able to flow to and from the lungs and a heavy mucus or phlegm is coughed up.
The bronchial tubes of people with chronic bronchitis may also have been irritated initially by bacterial or viral infections.
Once the bronchial tubes have been irritated over a long period of time, excessive mucus is produced constantly, the lining of the bronchial tubes becomes thickened, an irritating cough develops, air flow may be hampered, and the lungs are endangered.

 Information about Bronchiectasis
Bronchiectasis is caused by various types of infections which damage and weaken the bronchial walls and interfere with the action of the cilia.
Certain pneumonias which may be associated with measles and whooping cough, usually occurring in childhood may predispose to this condition by weakening the walls of the bronchial tubes and causing pockets of infection to form.
When this happens the wall of the tube is injured and air is prevented from passing beyond the obstruction.

 Diseases of the Bronchi
This disease occurs in two forms: hemorrhage into the bronchial tubes, called bronchorrhagia, in which the bleeding is into the bronchial tubes and is expectorated; and the form known as apoplexy of the lungs, called pneumorrhagia, the hemorrhage taking place into the aircells and the lung tissue.
If relief could not be had through the bronchial tubes, there is a possibility that the pus would burrow down into the peritoneal cavity or into the pericardium.
Where it breaks through into the bronchial tubes and is expectorated from the lungs, the disease is often mistaken and treated as such.

In the majority of patients who have blockage of the windpipe or large bronchial tubes from a tumor, this type of treatment brings immediate relief of shortness of breath.
When these tubes are blocked or squeezed shut by a tumor, symptoms such as shortness of breath, coughing up blood and collapse of the lungs may occur.
Sometimes the bronchial tubes or windpipe become narrow after recovery from breathing failure that required a tube to be placed in the windpipe (e.g., a tracheostomy tube).

Asthma is characterized by a reversible narrowing of the bronchial tubes in the lungs.
This narrowing is caused both by constriction of the muscles along the bronchial tubes and the accumulation of inflammatory cells within the tubes.
With asthma, bronchial tubes narrow too much, too often and too easily in response to a variety of substances that ordinarily wouldn't cause changes to the lungs.

This injury is a tear or break in the trachea (windpipe) or bronchial tubes, the major airways leading to the lungs.
The trachea or bronchial tubes can be damaged by a penetrating wound like a gunshot, or a blunt trauma like an automobile accident, but these are uncommon.
Injuries to the trachea or bronchi also may occur during medical procedures (e.g., fiberoptic bronchoscopy, placement of a breathing tube), but this is also very uncommon.

 What is Asthma? Inflammation of the Bronchial Tubes
Asthma is a disease of the bronchial tubes.
In an asthma attack, the bronchial tubes become inflamed, reducing the diameter of the bronchial tubes and restricting the amount of air going into and out of the lungs.
If left untreated, the bronchial tubes can become further irritated so that normal breathing is restricted.

The lungs consist of airways (also known as bronchial tubes, or bronchi), and air sacs (also known as alveoli).
The inner lining of your bronchial tubes would start to produce mucous — to trap any soot and ash that got down there.
These chemicals cause the bronchial muscle constriction, mucous secretion, swelling of the bronchial tube inner lining, and coughing.
