SSL (Secure Sockets Layer) is a standard security protocol for encrypting connections between a server and a client. This ensures all communications between the client and the server remain confidential. In most online implementations, the 'client' is an internet browser and the 'server' is a website to which the browser is connected.
Introductionâ¢ Oxygen and carbon dioxide diffuse between the alveoli and pulmonary capillaries in the lungs, andbetween the systemic capillaries and cells throughout the body.â¢ The diffusion of these gases, moving in opposite directions, is called gas exchange.Page 2.
it is made up of the alveoli's because they have very thin walls, only one cell thick to allow exchange/diffusion of gases through it and interchange of these gases with the blood, the capillary network means the gases can be easily delivered to the lungs and absorbed into the blood at the lung surface.est Answer: Alveoli are the actual sites of gas exchange between the lungs and the blood. They are incredibly thin to allow easy diffusion of gases (oxygen and carbon dioxide) back and forth.
