Why does the bird flu only attack the lower part of the human respiratory system and not the upper respiratory system?
Bird flu primarily targets the lower respiratory system due to the presence of specific receptors in the cells of the trachea and lungs that are more compatible with the virus. These receptors, known as avian-type sialic acid receptors, are more abundant in the lower respiratory tract, allowing the virus to efficiently enter and infect those cells. In contrast, the upper respiratory system has different receptor types that are less suited for avian influenza viruses, which may explain the virus's limited impact in that area.
What else can I help you with?
What is the two main division of the respiratory system?
lower and upper respiratory system
What are the two medical specialist for the respiratory system?
Pulmonologists treat the lower respiratory system, and otolargyngologists treat the upper respiratory system.
Acute lower respiratory tract infection?
Acute= severe. Lower Respiratory Tract= Respiratory system below the larynx. This refers to a pneumonia or a bronchitis.
What is the gateway to the lower respiratory system?
birds
Which body system would be most affected by a lower than normal atmospheric pressure?
The respiratory system would be most affected by a lower than normal atmospheric pressure. Decreased atmospheric pressure can lead to reduced oxygen levels in the blood, which can impact lung function and overall respiratory health.
What is the primary responsibility of the upper respiratory tract?
The upper respiratory system removes gross particles from the air, warms and humidifies it, and passes it to the lower respiratory system.
Do the nose and throat make up the lower respiratory system?
No, the nose and throat are the upper respiratory system; they are above the lungs (when you are standing up).
Which part of the lower respiratory tract is intimately in contact with the cardiovascular system?
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.
What is the laryngeal cartilage that keeps swallowed materials out of the lower respiratory system?
epiglottis
What is the body system involved in lung cancer?
Lung cancer is cancer of the lungs. Lung cancer that has not metastasized affects the lower respiratory system and different parts of the lungs.
What parts are in the lower respiratory tract?
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.
Which tissue maintains open airways in the lower respiratory system?
hyaline cartilagehyaline cartilage
