Verified step by step guidance

Step 1: Begin by identifying the primary function of the lungs, nose, and trachea. These structures are involved in the process of breathing, which includes the intake of oxygen and the removal of carbon dioxide.

Step 2: Understand the role of the respiratory system. It is responsible for gas exchange, allowing oxygen to enter the bloodstream and carbon dioxide to be expelled from the body.

Step 3: Compare the functions of the listed organ systems (nervous, circulatory, digestive, and respiratory) to determine which one aligns with the function of the lungs, nose, and trachea. For example, the nervous system controls communication and coordination, the circulatory system transports blood, and the digestive system processes food.

Step 4: Recognize that the lungs, nose, and trachea are specialized structures for air passage and gas exchange, which are key components of the respiratory system.

Step 5: Conclude that the correct organ system for the lungs, nose, and trachea is the respiratory system, as it matches their function and anatomical role.
