How are the lungs protected from bacterial infection?

How are the lungs protected from bacterial infection?

Nose: The cilia in the nasal passages are the first line of defense. The lung itself has macrophages that also destroy invasive bacteria. ...Read more

Lung (Definition)

Deoxygenated blood enters the lungs from the right side of the heart and travels to the lungs. When you inspire, oxygen flows into the lungs, transverses the capilliares and attaches to hemoglobin down a gradient. At the same time, co2 diffuses into the capilaries and is expelled with exhalation. Oxygen rich blood then flows to the left side of the heart and into the ...Read more

How alveloe in lungs fills with fluid by bacterial infection during pneumonia?

How alveloe in lungs fills with fluid by bacterial infection during pneumonia?

Pneumonia: The fluid filling the alveolus, secondary to infection, is quite simply pus/ purulence that develops as white blood cells kill the infectant. A good amount of damage to alveolar cells also occurs due to proteins released from white blood cells designed to recruit more cells to area of infection, creating breaks in cell lining. This causes increased swelling/ fluid leak into air spaces. ...Read more

What causes lung bacterial infection I am a non smoker?

What causes lung bacterial infection I am a non smoker?

Bacteria!: By definition, bacteria cause bacterial lung infection. Bacteria respond to antibiotics while viruses do not. Viruses are more common than bacteria & cause typical cold which won't respond to antibiotics. Average cough illness lasts 18 days so be patient. Best way to avoid upper respiratory infections (uris) is to wash hands & avoid being sneezed/coughed upon. And don't smoke (which you aren't). ...Read more

What's the difference between bacterial pneumonia and a bacterial infection of the lungs?

What's the difference between bacterial pneumonia and a bacterial infection of the lungs?

Not much: Pneumonia is usually used to refer to an infection in the clusters of breathing sacs in the lung. I suppose you could say a bacerial infection of the entry of the lung (tracheitis) could be defined better that way but I have never used it that way. To me they would seem to mean the same thing. ...Read more

Is amoxicillin good for a bad cough and bacterial infection in my lungs and/or chest?, had cough for 2 weeks, on amoxicillin for 2 days now.

Is amoxicillin good for a bad cough and bacterial infection in my lungs and/or chest?, had cough for 2 weeks, on amoxicillin for 2 days now.

No: A bacterial infection in the lungs would be pneumonia. Amoxicillin would not be a good choice for this because many of the bacteria that cause pneumonia are resistant to amoxicillin. A quinolone like levoquin, a tetracycline like Doxycycline or a combination of a cephalosporin like vantin or Ceftin (cefuroxime) plus zithromax would all be effective for community acquired bacterial infection. ...Read more

An X-ray said I had a slightly collapsed lung, my gp said just a bacterial infection, to repeat X-ray in 6 weeks I was not given any medication?

Viral?: Viral infections are not treated with antibiotics and treatment of a bacterial infection would depend on the bacteria causing the problem. Partial atelectasis, or a slightly collapsed area of lung, is a common finding on xray. Followup chest xray is a good way to make sure it resolves or doesn't get worse. ...Read more

What does a bacterial infection come from?

Wrong place ; time: Bacteria are everywher. They protect us from bad bugs by crowding them out or not allowing them to take hold; produce bacteriocidal compounds; help us digest food ; make essential vitamins for us. Unfortunately some bugs are not 'friendly'. If our immune system isn't intact (skin breakdown, chemo, poor nutrition, burns, immune diseases) these bad bacteria overcome our immune system and attack us. ...Read more

Are bacterial infections contagious?

Not the "infections": All bacteria are contagious, meaning that one person can smear some of his bacteria onto another's skin or other body part. The bacteria can then die, multiply on the surface (colonize the surface), or damage the person's cells and body parts (start an infection). No infection occurs in many cases, meaning the "infection" did not spread to the person even though the "bacteria" did spread to him. ...Read more

What are the causes of a bacterial infection and can it keep you from concieving?

Right PH: Bv is due to heavy vaginal colonies that cause a basic ph. You need an acidic ph in the vagina achieved by the acidophillus bacteria. First take antibiotics for both of you. Than use a vinegar acidic douch, and then take acidophillus from a probiotic pill like provela or eat danactive yogurt. This will give you the right ph always. ...Read more
