The Larynx:
• Part of the vocal cords and is located between the pharynx and the
trachea.
• It is made up of cartilage.
The Lungs:
• There are two and they are surrounded by the plural membrane.
• The lungs are divided up into lobes; two on the left and three on the
right.
The Trachea:
• Connects the larynx with the bronchus and progressively into the
smaller dimensions called the bronchiole.
• It is a flexible fibro elastic and muscular structure which allows the
neck to move.
• Allows the transport of oxygen from the atmosphere to the lungs and
carbon dioxide from the lungs into the atmosphere.
• It is strengthened by rings of cartilage to prevent it come collapsing.
• Contains cilia and mucus, which are hair like structures which traps
dust and bacteria which is within the air, as it passes down the
trachea.
Ciliated Lining:
• A collection of fine hairs that cover the inside of the trachea.
