The tractor or windpipe has special rings of cartilage to keep it open at all times so you can breathe if you are lying down asleep or on a trampoline. The oxygen molecule now travels down the trachea and they will go into either the left or the right lung via a tube called the bronchus. This bronchus then splits into smaller tubes called bronchioles and finally the oxygen molecule will make its way into a tiny air sac called an alveolar, these alveoli are surrounded by tiny blood vessels called capillaries and the oxygen molecule now passes across from the air into the blood via a process of diffusion. At the same time the carbon dioxide molecule goes the other way coming out of the blood and into the alveoli as you exhale. As you exhale the carbon dioxide will take the journey back up the bronchioles a bronchus the trachea and out of the mouth. This happens to millions of molecules with each breath have about 300 million alveoli in each lung. On average, you breathe like this 12 to 16 times a minute. Unlike your digestive system the respiratory system is a dead end. If something bad gets into your lungs it's very hard to get it back out. As usual the body has an answer to look very closely at the cells lining the tracker and the bronchi some of them have tiny little hairs on called cilia and in between these cells are other cells called goblet cells that are secreting mucus. This mucus traps dirt dust and bacteria before entered the lungs. The cilia then what this mucus up into the mouth where it can be swallowed to be killed by your stomach acid. There are many things that can go wrong with your lungs such as asthma, pneumonia and diseases associated with smoking such as emphysema and chronic bronchitis. However, if you have a problem a doctor may perform a bronchoscopy. This is when they put a tube with a light and the camera on it into your Airways and look for signs of inflammation or bleeding.
