Trachea – Your windpipe
Epiglottis – A flap of skin that drops over the opening to your larynx. It stops any food from going down your windpipe.
Cartilage – Rings around your windpipe, that keep it from collapsing. They are C – shaped.
Pleural Membrane – Your lungs are surrounded by the pleural membrane. It makes a slippery fluid, what makes the lungs spongy.
