Verified step by step guidance

Understand the question: The problem asks which structure is part of the respiratory system and located in the head and neck. The correct answer provided is 'Pharynx.'

Review the anatomy of the respiratory system: The respiratory system includes structures involved in breathing and gas exchange, such as the nasal cavity, pharynx, larynx, trachea, bronchi, and lungs.

Focus on the pharynx: The pharynx is a muscular tube located in the head and neck. It serves as a passageway for both air (to the respiratory system) and food (to the digestive system). It connects the nasal cavity and oral cavity to the larynx and esophagus.

Compare the other options: The thyroid gland is part of the endocrine system, the mandible is a bone of the skeletal system, and the parotid gland is part of the salivary glands in the digestive system. None of these are part of the respiratory system.

Conclude why the pharynx is correct: The pharynx is the only structure listed that is part of the respiratory system and located in the head and neck. It plays a critical role in directing air from the nasal cavity to the larynx.
