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.
External respiration is the process of exchanging oxygen and carbon dioxide between the air inside the alveoli and the blood in the capillaries of the lungs. Air inside the alveoli contains a higher partial pressure of oxygen compared to the blood in the capillaries.Conversely, blood in the lungs' capillaries contains a higher partial pressure of carbon dioxide compared to the air in the alveoli.ir inside the alveoli contains a higher partial pressure of oxygen compared to the blood in the capillaries. Conversely, blood in the lungs' capillaries contains a higher partial pressure of carbon dioxide compared to the air in the alveoli.
