Respiratory system: It is the anatomical system of an organism that introduces respiratory gases to the interior and performs gas exchange. In humans and other mammals, the anatomical features of the respiratory system include airways, lungs, and the respiratory muscles
What are the symptoms of acute bronchitis?
The symptoms of acute bronchitis can include:
What causes acute bronchitis?
Acute bronchitis is almost always caused by viruses that attack the lining of the bronchial tree and cause infection. As your body fights back against these viruses, more swelling occurs and more mucus is produced. It takes time for your body to kill the viruses and heal the damage to your bronchial tubes.
In most cases, the same viruses that cause colds cause acute bronchitis. Research has shown that bacterial infection is a much less common cause of bronchitis than we used to think. Very rarely, an infection caused by a fungus can cause acute bronchitis.
How do people get acute bronchitis?
The viruses that cause acute bronchitis are sprayed into the air or onto people’s hands when they cough. You can get acute bronchitis if you breathe in these viruses. You can also get it if you touch a hand that is coated with the viruses.
If you smoke or are around damaging fumes (such as those in certain kinds of factories), you are more likely to get acute bronchitis and to have it longer. This is because your bronchial tree is already damaged.
You should call your doctor if:
How is acute bronchitis treated?
Most cases of acute bronchitis will go away on their own after a few days or a week. It's a good idea to get plenty of rest, drink lots of fluids (for example, water and fruit juices) and increase the humidity in your environment. You can also take an over-the-counter pain reliever (such as ibuprofen or acetaminophen) to ease pain and lower fever. It is okay to take an over-the-counter cough suppressant if your cough is dry (not producing any mucus). It's best not to suppress a cough that brings up mucus because this type of cough helps clear the mucus from your bronchial tree faster.
If you smoke, you should quit. This will help your bronchial tree heal faster.
Some people who have acute bronchitis need medicines that are usually used to treat asthma. If you hear yourself wheezing, this indicates you may need asthma medicines. These medicines can help open the bronchial tubes and clear out mucus. They are usually given with an inhaler. An inhaler sprays the medicine right into the bronchial tree. Your doctor will decide if this treatment is right for you.
How long will the cough from acute bronchitis last?
Sometimes the cough from acute bronchitis lasts for several weeks or months. Usually this happens because the bronchial tree is taking a long time to heal. However, a cough that doesn’t go away may be a sign of another problem, such as asthma or pneumonia.
How can I keep from getting acute bronchitis again?
One of the best ways to keep from getting acute bronchitis is to wash your hands often to get rid of any viruses.
If you smoke, the best defense against acute bronchitis is to quit. Smoking damages your bronchial tree and makes it easier for viruses to cause infection. Smoking also slows down the healing process, so it takes longer for you to get well.
Boost your immune system.
What is chronic bronchitis?
Bronchitis is an inflammation (or irritation) of the airways in the lungs. Airways are the tubes in your lungs that air passes through. They are also called bronchial tubes. When the airways are irritated, thick mucus forms in them. The mucus plugs up the airways and makes it hard for air to get into your lungs. Symptoms of bronchitis include a cough that produces mucus (sometimes called sputum), trouble breathing and a feeling of tightness in your chest.
"Chronic" means that the condition last a long time. Chronic bronchitis is bronchitis that lasts longer than 3 months. Chronic bronchitis often occurs with emphysema, and together these diseases are called chronic obstructive pulmonary disease (COPD).
What causes chronic bronchitis?
Cigarette smoking is the main cause of chronic bronchitis. When tobacco smoke is inhaled into the lungs, it irritates the airways and they produce mucus. People who have been exposed for a long time to other things that irritate their lungs, such as chemical fumes, dust and other substances, can also develop chronic bronchitis.
How does my doctor know if I have chronic bronchitis?
Your doctor will ask you about your symptoms: Are you coughing up mucus? Are you having trouble breathing? Does your chest feel tight? How long have you had these symptoms? Do you smoke cigarettes? How many cigarettes do you smoke each day? How many years have you been smoking? Have you been breathing in other things that can irritate your lungs?
If your doctor thinks you have chronic bronchitis, you may be tested to find out if your lungs are damaged. You might have a pulmonary function test to see how well your lungs are working. During this test, you breathe into a machine that measures the amount of air in your lungs. Your doctor may also order blood tests and a chest X-ray.
What can I do to help my breathing and reduce my coughing?
If you smoke, the most important thing you can do is to stop. The more smoke you breathe in, the more it damages your lungs. If you stop smoking, you'll breathe
The symptoms of a cold develop slowly and can include:
What is H1N1 flu?
The H1N1 influenza (also called swine influenza or swine flu) is a respiratory infection caused by a virus found in pigs. H1N1 flu can infect humans.
Cold symptoms are generally more mild than flu symptoms.
Flu symptoms usually appear suddenly and can include:
What causes colds and the flu?
Viruses cause the common cold and the flu. Over 200 different viruses can cause colds. There are not as many viruses that cause the flu.
What can I do to feel better?
There's no cure for the common cold. All you can do to feel better is treat your symptoms while your body fights off the virus.

Can I prevent catching a cold or the flu?
You can reduce your risk of catching a cold or the flu by washing your hands frequently, which stops the spread of germs. Eating healthy, exercising and getting enough sleep also play a part in preventing colds and the flu because they help boost your immune system.
If you are sick, make sure that you cover your mouth when you cough and wash your hands often to prevent giving your cold or flu to others.
What are sinuses?
Sinuses are the air chambers in the bone behind your cheeks, eyebrows and jaw. They make mucus, a fluid that cleans bacteria and other particles out of the air you breathe. Tiny hairs called cilia sweep mucus out of your sinuses so it can drain out through your nose.
What is sinusitis?
Sinusitis is the name for a condition in which the lining of your sinuses becomes inflamed.
What causes sinusitis?
Anything that causes swelling in your sinuses or keeps the cilia from moving mucus can cause sinusitis. This can occur because of changes in temperature or air pressure. Allergies can cause sinusitis. Using decongestant nasal sprays too much, smoking, swimming or diving can also increase your risk of getting sinusitis. Some people have growths called polyps that block their sinus passages and cause sinusitis.
When sinusitis is caused by a bacterial or viral infection, you get a sinus infection. Sinus infections sometimes occur after you’ve had a cold. The cold virus attacks the lining of your sinuses, causing them to swell and become narrow. Your body responds to the virus by producing more mucus, but it gets blocked in your swollen sinuses. This built-up mucus is a good place for bacteria to grow. The bacteria can cause a sinus infection.
What are the symptoms of sinusitis?
The symptoms of sinusitis include:
How is acute sinusitis treated?
Treatment for sinusitis depends on the cause.
You can use a saline nasal spray, which will clean our your nasal passages and help clear congestion. Your doctor may recommend a prescription nasal spray that helps treat inflammation.
If you have sinus pain or pressure, your doctor may prescribe or recommend a decongestant to help your sinuses drain. Decongestants are generally only recommended for short-term use.
If your case of sinusitis is very severe and your doctor thinks the cause is bacterial, he or she may prescribe an antibiotic. You may take an antibiotic for 10 to 14 days, but you will usually start feeling better a couple of days after you start taking it. It is important to take antibiotics exactly as your doctor tells you and to continue taking it until it is completely gone, even after you’re feeling better.
If allergies are causing your sinusitis, your doctor may treat the allergy. Then the sinusitis will usually clear up on its own.
Tips on taking care of sinusitis
Avoid alcohol, which can worsen swelling in the sinuses.
