Carbon dioxide diffuses out of the tissues and into the blood, where it is dissolved in the plasma. While some of the carbon dioxide remains dissolved in the plasma, most carbon dioxide diffuses into our red blood cells.
A screencast is a digital movie in which the setting is partly or wholly a computer screen, and in which audio narration describes the on-screen action. It's not a new idea.
With our easy-to-use, free screen recorder for Windows and Mac you can capture any area of your screen with the option to add narration from your microphone and video from your webcam. You can record lectures, webinars, demos, games, Skype calls, etc and share free on Screencast-O-Matic.com, YouTube, or save directly to a video file.
