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.
So blood that is pumping through the capillaries in the lungs has a lo â¦ w concentration of O2 and a high concentration of CO2, in the alveoli it is high concentration O2 low concentration CO2. Therefore the 2 gases exchange across the alveoli membrane by diffusion trying to establish a concentration gradient.
