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.
Anatomy of the Respiratory System. The respiratory system is responsible for gaseous exchange between the external atmosphere and the blood. It delivers oxygen to the circulatory system for distribution to all body cells and aids in the removal of carbon dioxide.The major organs of the respiratory system are the nose, pharynx, larynx, trachea, bronchi and their smaller branches, and the lungs that contain air sacs called alveoli.t delivers oxygen to the circulatory system for distribution to all body cells and aids in the removal of carbon dioxide.
