Which respiratory structure acts as an "exit" for air leaving the respiratory system?Multiple Choicealveolitracheabronchinasal cavity

Break Down the Problem

1. Identify the respiratory structures involved.
2. Determine which structure serves as an exit for air.

Relevant Concepts

• The respiratory system consists of several structures that facilitate the process of respiration, including the nasal cavity, trachea, bronchi, and alveoli.

Analysis and Detail

3. • Alveoli: These are tiny air sacs where gas exchange occurs; they do not serve as exits for air.
   • Trachea: This is a major airway that conducts air to and from the lungs, but it's not the final exit for air leaving the body.
   • Bronchi: These are the passageways that branch from the trachea into each lung but, like the trachea, they are not the final exit.
   • Nasal Cavity: This structure is involved in filtering and humidifying the air entering the respiratory system, and serves as an exit route when exhaling air.

Verify and Summarize

4. The structure that serves as an "exit" for air leaving the respiratory system is the nasal cavity.

Final Answer

The nasal cavity acts as an "exit" for air leaving the respiratory system.
