Gas Exchange. Photo by: icholakov. Gas exchange is the process by which oxygen and carbon dioxide (the respiratory gases) move in opposite directions across an organism's respiratory membranes, between the air or water of the external environment and the body fluids of the internal environment.

Two important aspects of gas exchange in the lung are ventilation and perfusion. Ventilation is the movement of air into and out of the lungs, and perfusion is the flow of blood in the pulmonary capillaries. For gas exchange to be efficient, the volumes involved in ventilation and perfusion should be compatible.

Each alveoli connects with capillaries through a thin basement membrane. Gases such as oxygen and carbon dioxide diffuse across the thin basement membrane and are exchanged between the alveoli of the lungs and the capillaries. Gas exchange occurs by the process of diffusion.

~gas exchange organ in air-breathing vertebrates and other animals. ~made up of small chambers, each chamber having a huge respiratory surface for the diffusion of oxygen into the blood and the diffusion of carbon dioxide out of the blood. ~fills up a large part of the chest cavity.

Key Points. 1  The purpose of the respiratory system is to perform gas exchange. 2  Gases tend to equalize their pressure in two regions that are connected; in such a situation, the respective pressure of each gas is known as that gas's partial pressure..

Gas exchange. Gas exchange or respiration takes place at a respiratory surface; a boundary between the external environment and the interior of the body. For unicellular organisms the respiratory surface is simply the cell membrane, but for large organisms it usually is carried out in respiratory systems.

Quick Answer. In the respiratory tract, gas exchange takes place in the alveoli of both of the lungs. The alveoli are small sacs of air that are covered in a material known as surfactant. This substance allows the alveoli to expand and contract during inhalation and exhalation.
