Create an analogy of the respiratory system to compare it with a non-living system.

An analogy that can link with the process of respiration can be a factory. For example, the way that the factory processes raw goods to make manufactured goods is similar to how the respiratory system takes in molecules and breaks it down into energy.

Is there any answer choices?

answer: - b cells

explanation: -

there are many types of white blood cells present in our body. one such class of white blood cells are the lymphocytes. the b cells belong to the lymphocyte class of wbcs. the b cells perform their action against the pathogen by producing specialised proteins called as antibodies. these antibodies are produced as and when the b cells encounter pathogens in response to the antigens present on the surface of the pathogen. these antibodies bind to the antigens present on the pathogen and then, target them for destruction by other cells of the immune system.

so, the b cells mediate their action by identifying the antigens present on the surface of the pathogens and then producing antibodies in return to mediate its effect.
