1. List the functions of the respiratory system

Primarily function = gas exchange

pH balance

• Speech/vocalisation

angiotensin 1 to angiotensin 2 occurs in the lungs

1. Identify the main skeletal elements forming the roof, lateral wall and septum of the nasal cavity

the roof of the nasal cavity is formed by 3 main things

including = sphenoid bone, Frontal bone, ethmoidal bone/cribiform plate

the medial wall/septum of the nasal cavity is made up from 3 main things

including = vomer bone, septum cartillage and the perpendicular plate of the ethmoidal bone

the lateral wall of the nasal cavity is made up from

1. Describe the neurovascular supply of the nasal cavity and paranasal sinuses

the sympathetic supply of the nasal cavity = peri-arterial fibres

the parasympathetic supply = the facial nerve
