Nasal passages:
-air enters the body through the nasal passages during normal breathing.
Larynx:
-air passing over the larynx produces sounds for speaking.
Trachea:
-air passes down the trachea to the lungs, the trachea is a flexible tube, stiffened by rings of cartilage.
Bronchi:
-the trachea splits into two bronchi's, carrying air to each of the lungs.
Brochioles:
-the bronchi split inot t smaller tubes called bronchioles that distribute air to the alveoli.
Alveoli:
-aire eventually reaches millions of tiny air sacks in the lungs called alveoli, there walls are so thin thats gasses can pass through
Ribs:
-the rib cage protects the lungs, but is mobile enough to allow the chest to expand and contract during breathing
Intercostal muscles:
-the muscles between the ribs help your chest to expand when you breathe in.
Diaphram:
-this is the sheet of muscle inder the lungs, it contracts and moves down to expand the chest cavity you breathe in.
