Question

Quizplus · Accepted Answer

Anatomic dead space refers to the airways of the respiratory system that conduct air without participating in gas exchange. These include the nose, mouth, pharynx, larynx, trachea, bronchi, and bronchioles up to the terminal bronchioles. Therefore, the boundaries of anatomic dead space are from the nose and mouth through the terminal bronchioles. Choices B, C, and D include areas beyond the terminal bronchioles where gas exchange occurs, and are not considered part of the anatomic dead space.
