Question

nervous system, endocrine system

Answer 1

Of what species?  There is some variation in the structure and functioning of these systems depending upon the animal to which you are referring!

For example the respiratory organs of an insect would be the spiracles and tracheal tree.

For a fish, it would be primarily the operculum, gills, and circulatory system.

For mammals, nares, nasal pharynx, epiglottis, glottis, larynx, trachea, bronchi, bronchial tree, lungs, alveoli, capillary beds.

You need to be more specific with shorter, concise questions!
