The epithelium of the respiratory tract contains mucous cells which adds moisture and there are blood vessels close to its' surface that add warmth to the air.
ciliated mucous membranes
The nasal cavity warms and moistens air as it enters the body.
They don't really are related because it says "what is the function of the nasal cavity and these differ", the nasal cavity is used for us to breathe through the two openings on our nose called the "nostrils".
The pharynx, most commonly known as the throat, serves duel purposes. Not only does it move the air into your lungs, but it also moves food into your stomach. About five inches long, the pharynx is separated into three distinct regions, chosen by location and function: the nasopharynx, the oropharynx, and the laryngopharynx

The pharynx is part of two systems, the digestive and the respiratory. It moistens, filters and warms the air taken into the lungs.

During respiration it is the nose or nasal cavity that filters the air using mucous and hair within the nose, warms the air and moistens. This is performed when inhaling.
Warms the air, clears the air of dirt and dust, and moistens the air.
The nasal cavity warms and moistens air as it enters the body.
The respiratory system warms the air to body temperature as it passes through the nasal cavity to prevent damage to the delicate lung tissues. The system humidifies the air by adding moisture to it through the mucous membranes in the respiratory tract, making it easier for oxygen to pass through the respiratory membrane in the lungs. It filters the air by trapping particles and pathogens in the mucus lining of the respiratory tract and then removing them through processes like coughing and swallowing.
The Nostrils or the Nose.
The upper respiratory system removes gross particles from the air, warms and humidifies it, and passes it to the lower respiratory system.
That would be the nose. It warms, filters, and humidifies room air. Its our built in heat and moisture reclaimer.
