This exchange process occurs in the alveoli (air sacs) in the lungs. In fish and many invertebrates, respiration takes place through the gills. Other animals, such as insects, have respiratory systems with very simple anatomical features, and in amphibians even the skin plays a vital role in gas exchange.Plants also have respiratory systems but the directionality of gas exchange can be opposite to that in animals.ee also: Respiratory tract. The respiratory system (called also respiratory apparatus, ventilatory system) is a biological system consisting of specific organs and structures used for the process of respiration in an organism.
