Breathing, coughing, sneezing… All these actions are controlled by the fascinating respiratory system. Your respiratory system does all sorts of things in order to keep the intake of oxygen and exhale carbon dioxide running smoothly. After reading this piece, maybe you will think differently of the respiratory system.
When you inhale, the air travels from the mouth and nose to the larynx and down the trachea, a tube that is right next to the passage foods take. The trachea stretches down to the chest cavity, and splits into two tubes called the bronchi. The bronchi then splits into bronchial tubes which then split into more smaller tubes, connecting to small sacs called alveoli. The oxygen in the alveoli diffuses into the bloodstream while carbon dioxide, the waste from the body’s tissues, would diffuse into the alveoli to be exhaled out. The alveolar walls are extremely thin, in order to make the gas exchange efficient and fast. Because alveoli have lots of capillaries around them, the oxygen would be quickly transferred into the bloodstream, which also means carbon dioxide in the bloodstream would also be quickly transferred into the alveoli. The rib cages and diaphragm play a key role in the respiratory system. The rib cage is raised by external intercostal muscles when breathing in, and lowered by internal intercostal muscles when breathing out. The rib cage would also protect the lungs and the heart so that when the person falls the fragile organs would be protected.
There are many crucial parts and functions of the respiratory system that keep the system and the body healthy and normal. Cartilage plays a huge role in the respiratory system. A flap of cartilage called epiglottis prevents food from entering the trachea....
