What is the Nasal Passage?
Air enters the body through the Nasal Passages during normal breathing.

What is the Larynx?
Air passing over the Larynx produces sounds for speaking.

What is the Epiglottis?
The Epiglottis is a flap of cartilage that sits beneath the tounge that closes over the Trachea while you're eating to prevent food entering your airways.

What is the Trachea?
Air passes down the Trachea to the lungs. The Trachea is a flexible tube, stiffened by rings of cartilage.
4 of 17
What are Bronchus?
The Trachea splits into two bronchi, carrying air to each of the lungs.
5 of 17
What are Bronchioles?
The Bronchi split into smaller tubes called Bronchioles that distribute air to the alveoli.
6 of 17
What are Alveoli?
Air eventually reaches millions of tiny air sacs in the lungs called alveoli. Their walls are so thin that gases can pass through.

What do the Ribs do?
The Rib cage protects the lungs, but is mobile enough to allow the chest to expand and contract during breathing.
8 of 17
What are the Intercostal Muscles?
The muscles between the ribs help your chest to expand when you breathe in.
9 of 17
What is the Diaphragm?
This is a sheet of muscle under the lungs. It contracts and mives down to expand the chest cavity when you breathe in.

What is Oxyhaemoglobin?
Haemoglobin combines with oxygen in the lungs to form a bright red chemical called Oxyhaemoglobin. When the blood gets to a place where oxygen is needed Oxyhaemoglobin releases its oxygen.

What is breathing rate?
Sometimes called Respiratory Rate, is the frequency of breathing measured in breaths per minute. Normal breathing rate at rest is approx. 12 breaths per minute.
12 of 17
What is Tidal Volume?
The amount you breathe in and out in one normal breath.
13 of 17
What is Minute Volume?
The volume of air you breathe in one minute.
14 of 17
What is Vital Capacity?
The maxium volume of air you can breathe out after breathing in as much as you can.
15 of 17
What is Residual Volume?
The amount of air left in your lungs after you have breathed out as hard as you can.
16 of 17
How can you calculate someones Minute Volume?
Minute Volume = Volume of air someone breathes in one breath x their respiratory rate
