The shape of the nose is determined by the ethmoid bone and the nasal septum.

The human pharynx is part of the digestive system and also the respiratory system.

The larynx is an organ in the neck involved in breathing, sound production, and protecting the trachea against food aspiration.

Voices produce sounds through a steady flow of air through the larynx, which causes vibrations and creates fluctuations in air pressure.

The trachea, or windpipe, is a tube that connects the pharynx or larynx to the lungs, allowing the passage of air.
