Respitory System

Primary functions of the repiratory system: Supplies oxygen throughout the body, gets rid of carbon dioxide, regulates the body's ph balance. There are three main stages of respiration.The first stage is the exchange of gases within the lungs large capillaries (external respiration). The next stage is internal respiration which is the exchange of gases between the cells and blood. The next stage of respiration is cellular respiration which is metabolic activity within the cells that use oxygen and makes carbon dioxide..

Steps of the Respiration Process
Air is breath in through the nostrils-passes through the nasal cavities. Next it goes to the pharynx then to the larynx then to the trachea. The trachea divides into the left and right bronchi. The bronchi's branch out many times until it finally get to the broncioles. That is where the exchange of gasses between the blood and the lungs occur. The final process of the respiratory system happens to the lungs.
