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 alveoli are the primary gas exchange units of the lung quite simply they are the point where the gas blood barrier is thin enough to permit rapid gas exchange to get into the blood oxygen is diffused through the alveolar epithelium a thin interstitial space and the capillary endotheliumhe alveoli are the primary gas exchange units of the lung quite simply they are the point where the gas blood barrier is thin enough to permit rapid gas exchange to get into the blood oxygen is diffused through the alveolar epithelium a thin interstitial space and the capillary endothelium
