lower and upper respiratory system
Pulmonologists treat the lower respiratory system, and otolargyngologists treat the upper respiratory system.
Acute= severe. Lower Respiratory Tract= Respiratory system below the larynx. This refers to a pneumonia or a bronchitis.
The lung is the gateway between the air and the circulatory system. It takes oxygen out of the air, and releases carbon dioxide into it.
The upper respiratory system removes gross particles from the air, warms and humidifies it, and passes it to the lower respiratory system.
No, the nose and throat are the upper respiratory system; they are above the lungs (when you are standing up).
The lungs are intimately in contact with the cardiovascular system. The alveoli in the lungs is where gas exchange occurs from the cardiovascular system and the respiratory system.
The upper respiratory system employs several mechanisms to filter out dust and bacteria before they reach the lower respiratory system. Cilia, tiny hair-like structures lining the nasal passages and trachea, sweep mucus and trapped particles upward toward the throat, where they can be swallowed or expelled. Additionally, mucus traps dust, pathogens, and other debris, preventing them from entering the lungs. The rich blood supply in the upper respiratory system also helps warm and humidify the air, further protecting the delicate tissues of the lower respiratory system.
The main parts of the lower respiratory tract are the trachea, two bronchial tubes, the bronchioles, and the lungs. The upper and lower respiratory tracts come together to make up the entire respiratory system.

Lung cancer is cancer of the lungs. Lung cancer that has not metastasized affects the lower respiratory system and different parts of the lungs.
