There is direct relationship between the habitat of the organism and the respiratory structures used for gas exchange. Animals that live in water use gills while those on land may use the tracheal or lungs for respiration.
The primary function of the respiratory system is to provide for the exchange of respiratory gases(O2, CO2) between the organism and the environment.
The lungs are part of the respiratory system. The respiratory system is involved in the intake and exchange of oxygen and carbon dioxide between an organism and the environment.
Gas exchange takes place at a respiratory surface-a boundary between the external environment and the interior of the organism.
Gas exchange takes place at a respiratory surface-a boundary between the external environment and the interior of the organism. For unicellular organisms the respiratory surface is governed by Fick's law, which determines that respiratory surfaces must have:a large surface areaa thin permeable surfacea moist exchange surface.

The respiratory system is the anatomical system of an organism that introduces respiratory gases to the interior and performs gas exchange. In humans and other mammals, the anatomical features of the respiratory system include airways, lungs, and the respiratory muscles. Molecules of oxygen and carbon dioxide are passively exchanged, by diffusion, between the gaseous external environment and the blood. This exchange process occurs in the alveolar region of the lungs.[1] 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. Plantsalso have respiratory systems but the directionality of gas exchange can be opposite to that in animals. The respiratory system in plants also includes anatomical features such as holes on the undersides of leaves known as stomata.[2]
A natural relationship in which one organism lives in or on another organism and benefits from the relationship while the other organism may be harmed is a parasitic relationship.
The respiratory system is the anatomical system of an organism that introduces respiratory gases to the interior and performs gas exchange. In humans and other mammals, the anatomical features of the respiratory system include airways, lungs, and the respiratory muscles. Molecules of oxygen and carbon dioxide are passively exchanged, by diffusion, between the gaseous external environment and the blood.
There are two place where this process occurs: i) the Lungs, and ii) the Capilliaries.
The term respiration denotes the exchange of the respiratory gases (oxygen and carbon dioxide) between the organism and the medium in which it lives and between the cells of the body and the tissue fluid that bathes them.
Because alveoli have to be able to exchange gases freely like oxygen and get rid of carbon dioxide. Also, oxygen must have moisture to benefit breathing.
