Acute bronchitis is the inflammation of mucous membranes of the bronchial tubes.

 The signs and symptoms of acute bronchitis.

The following are the most common symptoms for acute bronchitis, however, each individual may experience symptoms differently. The symptoms of acute bronchitis may resemble other conditions or medical problems. Please consult your doctor for a proper diagnosis.

  • runny nose
  • malaise

  • sore throat
  • early-dry, non-productive cough
  • later- abundant mucus-filled cough

Bronchitis is an inflammation of the breathing tubes (airways) that are called bronchi, which causes increased production of mucous and other changes. Although there are several different types of bronchitis, the two most common are acute and chronic.

Acute bronchitis is usually caused by infectious agents such as bacteria or viruses. If may also be caused by physical or chemical agents, dusts, allergens, strong fumes, and those from chemical cleaning compounds, or tobacco smoke. (Acute asthmatic bronchitis may happen as the result of an asthma attack, or it may be the cause of an asthma attack.)

Acute bronchitis is usually a mild, and self-limiting condition, with complete healing and return to function.

Acute bronchitis may follow the common cold or other viral infections in the upper respiratory tract. It may also occur in people with chronic sinusitis, allergies, or those with enlarged tonsils and adenoids. It can be serious in people with pulmonary or cardiac diseases. Pneumonia is a complication that can follow bronchitis.

What makes up the respiratory system?

  • nose
  • pharynx
  • larynx
  • trachea
  • bronchi
  • lungs
  • The upper respiratory tract includes the : nose, nasal cavity, ethmoidal air cells frontal sinuses, maxillary sinus larynx  and the trachea.
  • The lower respiratory tract includes the : lungs, bronchi and alveoli.

Respiration is the act of breathing: inhaling (inspiration - taking in oxygen and exhaling (expiration) - giving off carbon dioxide.

The function of the lungs take in oxygen, which cells need to live and carry out their normal functions. The lungs also get rid of carbon dioxide, a waste product of the body's cell. When you have acute bronchitis, it becomes very hard for your lungs to carry out their proper function.

The lungs are a pair of con-shaped organs made up of spongy, pinkish-gray tissue. They take up most of the space in the chest, or the thorax (the part of the body between the base of the neck and diaphragm). The lungs are enveloped in a membrane called the pleura.

The right lung has three sections, called lobes. The left lung has two lobes. When you breath, the air:

  • enters the body through the nose or the mouth
  • travels down the throat through the larynx (voice box) and trachea (windpipe)
  • goes into the lungs through tubes called main-stem bronchi. (One main-stem bronchus leads to the right lung and one to the left lung.
