Final answer:
B. Nasal Cavity
The answer to the question is the Nasal Cavity (Option B), which is a multi-functional space used for respiratory functions and also contains chemoreceptors for smell and taste.
Step-by-step explanation:
The cavity described in the question, made up of two irregular-shaped spaces separated by cartilage and used as a hidden injection point for tissue building the face, is the Nasal Cavity (Option B). The nasal cavity is divided at the midline by the nasal septum. It is an air-filled space within the skull, located above and behind the nose in the middle of the face. The nasal cavity warms and humidifies as well as helps trap particles in the inhaled air. It contains chemoreceptors that contribute to the sense of smell and taste. The cavity also has a connection to the paranasal sinuses, which are air-filled spaces in the frontal, maxilla, sphenoid, and ethmoid bones, contributing to the structure and function of the nasal cavity.
