How Does It Protect The Respiratory System?
a. Mucous Membrane
It traps dust, dirt, germs (allergens, viruses, bacteria, etc.). Also it keeps your insides from drying out.
b. Hair in the nasal cavity
It traps dust, dirt, germs (allergens, viruses, bacteria, etc). Also it keeps your insides from drying out
c. Epiglottis
It’s a flap that covers the opening to your lungs while you're swallowing so you don't inhale food.
d. Coughing
When you cough you are either releasing mucous or germs or some other irritant in the lungs.
e. Incomplete rings of Trachea
Prevent the trachea and bronchioles from collapsing and closing up.
f. Fat and protein film lining the inner wall of the alveoli
Surfactant in the alveoli causes them to effectively stay open during the whole respiration/breathing process. When there is lack of surfactant the alveoli can collapse on themselves causing less surface area for gas exchange, hence causing breathing difficulties/shortness of breath due to the decreased ability for oxygen exchange.
g. Pleura& lymph between the two layers
They play a critical role in immunological responses in both local and systemic diseases. It is positioned to respond to inflammatory changes in the lung parenchyma.
The pleura functions not only as a mechanical barrier, but also as an immunologically and metabolically responsive membrane that is involved in maintaining a dynamic homeostasis in the pleural space.
h. Rib cage
The rib cage are a set of bones radiating from the Thoracic region of the vertebral column (not to be confused with the vertebral cord which is located inside the vertebral column). These bones are the ribs and sternum (or
