Final answer:
The correct medical term for the nostrils is nares, which are the openings in the nasal cavity that allow for air passage.
Step-by-step explanation:
The medical term for the nostrils is nares. This term refers to the openings of the nasal cavity, which allows the passage of air into the respiratory system. The nasal cavity is lined with mucous membranes and is divided by the nasal septum. The nasal conchae are the bony structures that extend into the nasal cavity and serve to increase the surface area, aiding in warming and humidifying the air as it passes through. Moreover, the nares contain hair follicles and sebaceous glands, playing a role in filtering out large debris.
Adenoids, also known as the pharyngeal tonsils, are located at the superior portion of the nasopharynx and are part of the lymphatic system, while polyps are benign growths that can occur in the nasal cavity but are not synonymous with nostrils. Consequently, the final answer to the student's question is clearly A) nares.
