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.
The capillaries near the alveoli contain blood low in oxygen and high in CO2. As the blood passes the alveoli gaseous exchange occurs. Oxygen from the alveoli diffuses into the blood in the capillaries and CO2 diffuses out of the blood into the alveoli then it is breathed out.
