- nasal cavity
- pharynx
- larynx
- trachea
- bronchi
- bronchioles
- terminal bronchioles
What parts of the respiratory system to the respiratory zone contain?

- alveoli ducts
- alveoli
What are five functions of the nasal structure? (why do we have a nose)
- Smell
- Filter - hairs, sneezing
- Moistens - mucus
- Warms - warms the air, highly vascularised

Yes - although mens are larger and protrude more
What are the main structures within the Larynx?
- Thyroid Cartilage

What is the epiglottis?
A thin elastic cartilaginous structure located at the roof of the tongue, which folds over the glottis to prevent food and liquid from entering the trachae during swallowing
What is the trachea?
- C-shaped rings of smooth muslce cartilage that is lined with a pseudostratified ciliated columnar epithelium.
What is the purpose of the rings of C-shaped cartilage in the trachea?
To keep the airway open when the oesophagus takes bolus of food downward
How many branches are thre in the bronchial tree?
23
what are the first six branches in the bronchial tree?
