Pneumonia, pleurisy or bronchitis can be the result of respiration infections by a virus or bacteria.
The air passage
If bacteria are not trapped before air enters the lungs by the respiratory system's natural defenses (such as the mucous lining and cilia in the respiratory tract), they may reach the lungs and cause infection. This can result in conditions like pneumonia or bronchitis.
The lungs are protected from bacterial infection through various mechanisms, such as the mucociliary escalator, which helps to trap and remove bacteria from the respiratory tract. Additionally, the lungs have immune cells like macrophages that can engulf and destroy bacteria. The presence of antibodies in the respiratory tract also helps to neutralize and eliminate bacterial invaders.
Influenza is a virus. It is a respiratory virus that infects the nose, throat, and sometimes the lungs. It is not caused by bacteria or fungi.
it is the bacteria that causes whooping cough and is found in the upper respiratory tract of the lungs.
Respiratory system
lungs is respiratory organ of cow
If cilia are paralyzed then mucus-containing particles, including bacteria, will remain in the lungs and may cause a respiratory infection.
Mucus enters the lungs through tiny hair-like structures called cilia that line the respiratory tract. It helps to trap and remove harmful particles, such as bacteria and dust, from the air we breathe. This helps to protect the lungs from infections and maintain respiratory health.
Chronic high blood pressure combined with heart failure can push fluid into the lungs.
The respiratory system. The alveoli are air sacs in the lungs.
The lungs are the major organs of the respiratory system. The respiratory system consists of nose, nasal passages, nasopharynx, larynx, trachea and lungs.
