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 exchange of oxygen and carbon dioxide takes place in between the alveoli and capillaries. Oxygen moves through the cell membrane of the capillaries of the alveoli and thenâ¦ into the blood. Then oxygen is picked up by hemoglobin, and carried to all the body cells.
