Every cell in an animal requires oxygen to perform cellular respiration cellular respiration is the process by which animals take in oxygen and exchange it for carbon dioxide and water as waste products animals have specialized systems that help them do this successfully and efficiently even a. 1 abnormal ventilation, abnormal gas exchange ventilation and gas exchange objective: to achieve adequate tissue oxygenation and remove metabolically.
The purpose of the respiratory system is to perform gas exchange pulmonary ventilation provides air to the alveoli for this gas exchange process.

Gas exchange or respiration in humans is the means by which getting oxygen from air into the blood and carbon dioxide out of the blood into the air. Gas exchange exchanging gases with theenvironment: animals and plants. During the flutter phase of discontinuous gas exchange cycles, spiracles open slightly and close in rapid succession as a result of the negative pressure within the tracheal system, created during the closed phase, a small amount of air from the environment enters the respiratory system each time the spiracles are opened.

Gaseous exchange is the diffusion of the oxygen and carbon dioxide that takes place in the alveoli part of the lungs.
Gas exchange occurs in the alveoli of the lungs in these alveoli, carbon dioxide moves from the red blood cells into the alveoli, and oxygen moves from the alveoli into the red blood cells oxygen enters the body through the act of inhaling oxygen molecules travel through the nose down the. Respiratory surface: a surface over which gaseous exchange takes place (by diffusion) efficient respiratory surfaces have the following properties (refer back to cell structure and function for info on diffusion and fick's law) : large surface area high permeability very thin (typical thickness 1 mm) kept moist (o2 and co2 diffuse more rapidly. The field of pulmonary gas exchange is mature, with the basic principles developed more than 60 years ago arterial blood gas measurements (tensions and concentrations of o2 and co2) constitute a mainstay of clinical care to assess the degree of pulmonary gas exchange abnormality.
