Pharynx
The part of the throat that = behind the oral cavity and nasal cavity
Larynx (voice box)
the organ in the neck involved in breathing and sound production
Windpipe
A cartilaginous tube that connects the pharynx and larynx to the bronchi
Bronchi (singular: bronchus)
Two airways that conduct air from the windpipe into the bronchioles
Bronchioles
Tiny side branches of the bronchi that connect the alveoli
Alveoli (singular: alveolus)
Microscopic air sacs at the end of bronchioles, where gas exchange takes place
Ciliated cells
Hair-shaped cells that sweep mucus to your pharynx
Olfactory cells
Sensory receptors high up in the nasal cavity that can detect odours
Uvula
A small flap at the back of the throat that closes the nasal cavity when you swallow
Epiglottis
A thin plate of flexible cartilage on front of the windpipe that folds back over and closes the windpipe when you swallow
Vocal folds
Elastic folds of tissue in the larynx which produce sound when exhaled air causes them to vibrate
Pitch
A measure of how high a sound is
Amplitude
