MICROANATOMY

Detailed explanation-1: -Pneumonia is an infection that inflames the air sacs in one or both lungs. The air sacs may fill with fluid or pus (purulent material), causing cough with phlegm or pus, fever, chills, and difficulty breathing. A variety of organisms, including bacteria, viruses and fungi, can cause pneumonia.

Detailed explanation-2: -Pneumonia is an infection of the lungs that may be caused by bacteria, viruses, or fungi. The infection causes the lungs’ air sacs (alveoli) to become inflamed and fill up with fluid or pus. That can make it hard for the oxygen you breathe in to get into your bloodstream.

Detailed explanation-3: -If a person has pneumonia, the alveoli in one or both lungs fill with pus and fluids (exudate), which interferes with the gas exchange. This is sometimes known as ‘consolidation and collapse of the lung’.

Detailed explanation-4: -Common symptoms of pneumonia include: a cough – which may be dry, or produce thick yellow, green, brown or blood-stained mucus (phlegm) difficulty breathing – your breathing may be rapid and shallow, and you may feel breathless, even when resting.

Detailed explanation-5: -Immune cells attack the germs and may cause inflammation of your air sacs, or alveoli. Inflammation can cause your air sacs to fill up with fluid and pus and cause pneumonia symptoms.
