Learning Outcomes. Discuss how gases move across the alveoli; In the body, oxygen is used by cells of the body’s tissues and carbon 2021-04-10 · Gas exchange is the process by which oxygen and carbon dioxide move between the bloodstream and the lungs. This is the primary function of the respiratory system and is essential for ensuring a constant supply of oxygen to tissues. This article will discuss the principles of gas exchange, factors affecting the rate of exchange and relevant clinical conditions.

Gas exchange occurs Gas exchange takes place at the surface of the fluid (the 'fluid/gas interface') at the ends of the finer tubes - tracheoles - where oxygen dissolves in the fluid and CO 2 leaves it. The fluid is in contact with a thin layer of liquid covering the internal muscles etc. and dissolved oxygen is passed to them by diffusion.

Alveoli are thin-walled, sac-like structures lined by a single layer of flattened squamous epithelial cells: type I pneumocytes. This extremely thin nature of the type I pneumocytes facilitates gas exchange across their surface. The alveolar wall, or septum, consists of capillaries and minimal connective tissue support. Gas exchange takes place in the millions of alveoli in the lungs and the capillaries that envelop them. As shown below, inhaled oxygen moves from the alveoli to the blood in the capillaries, and carbon dioxide moves from the blood in the capillaries to the air in the alveoli. Alveoli are lined by many capillaries. The surface of the alveolus is moist.

Alveoli and gas exchange

The surfaces of the alveoli are covered with capillaries. These are narrow blood vessels which are one cell thick. Oxygen is passed from the alveoli into the bloodstream, which then distributes it to cells where it is used to unlock energy from food. 6.4.3 Describe the features of alveoli that adapt them to gas exchange. Even though alveoli are so small there are huge numbers of them which results in a large surface area for gas exchange.
