Verified step by step guidance

Begin by understanding the levels of organization in the human body, which include: chemical, cellular, tissue, organ, organ system, and organism levels.

Recognize that the human respiratory system is composed of multiple organs working together, such as the lungs, trachea, and bronchi.

Identify that an organ system level involves a group of organs that work together to perform complex functions necessary for the survival of the organism.

Consider the function of the respiratory system, which is to facilitate the exchange of oxygen and carbon dioxide between the body and the environment, a task that requires coordination among various organs.

Conclude that the human respiratory system fits the organ system level of organization, as it involves multiple organs working in concert to achieve a common physiological function.
