The main function of the respiratory system is gaseous exchange. This refers to the process of Oxygen and Carbon Dioxide moving between the lungs and blood. Diffusion occurs when molecules move from an area of high concentration (of that molecule) to an area of low concentration.
Two of the major functions of the respiratory system (the lungs and the tubes through which air pass into and out of the body) are to: 1. Provide oxygen (O 2) to the tissues of body via the lungs.2. Eliminate carbon dioxide (CO 2) from the tissues of the body via the lungs.wo of the major functions of the respiratory system (the lungs and the tubes through which air pass into and out of the body) are to: 1.
