Tiny hairs called cilia (SIL-ee-uh) protect the nasal passageways and other parts of the respiratory tract, filtering out dust and other particles that enter the nose through the breathed air.
The diaphragm, a dome-shaped sheet of muscle that separates the chest cavity from the abdomen, is the most important muscle used for breathing in (called inhalation or inspiration). The diaphragm is attached to the base of the sternum, the lower parts of the rib cage, and the spine.
Larynx is part of your respiratory system. It's a hollow tube that lets air pass from your throat (pharynx) to your trachea on the way to your lungs. It also contains your vocal cords and is essential to human speech, so it's often called the voice box.
In your lungs, the main airways (bronchi) branch off into smaller and smaller passageways — the smallest, called bronchioles, lead to tiny air sacs (alveoli).
Mucosae line the paranasal sinuses and help to warm and humidify the air we inhale. When air enters the sinuses from the nasal cavities, mucus formed by the muscosae drains into the nasal cavities.
