The latest research suggests your heart has a brain, and may be far more complex than imagined. This emotion, for example, boosts your heart attack risk five-fold, and your stroke risk three-fold.
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.
The respiratory system is made up of airways (your nose, mouth, voice box, windpipe and bronchial tubes) and the lungs and the muscles and blood vessels connected to them.he respiratory system's primary function is to supply oxygen to all the parts of your body. It accomplishes this through breathing: inhaling oxygen-rich air and exhaling air filled with carbon dioxide, which is a waste gas.
