Hey there! My name is Bubert Lung and my brother’s name is Theo Lung. Together we make up the lungs of the human body. You can probably guess that we are part of the most important body system in the Human Body System, the respiratory system. The respiratory system has the most essential role in the body, it gives us oxygen! Humans breathe about 20,000 times each day! This would not be possible without the respiratory system. This body system includes the nose, throat, windpipe, and lungs.
The respiratory system gives oxygen to the body’s cells while taking carbon dioxide out of the human body; if you have no oxygen, your body will not be able to take carbon dioxide out. It is also the process which allows humans to breathe with oxygen and many other elements. The air will then enter the bloodstream and flow throughout the body. Bob, the heart, always brags about how “important the circulatory system is” and he completely ignores the importance of the respiratory system- it helps you breathe! The primary organs of the respiratory system are the nose, pharynx, epiglottis, larynx, trachea, bronchi, and of course the lungs! The nose is the organ of smell and entrance to the respiratory tract. Air comes into the body via the nose and as it passed over the specialized cells of the olfactory system, the brain recognizes and identifies the smell. The pharynx-throat- is the passageway for food to the esophagus, a muscular tube connecting the pharynx with the stomach, to the larynx. The larynx controls the flow of air while you breathe and is made of cartilage. The Epiglottis has a lid like structure and covers the larynx during swallowing to prevent food from entering the airway. The trachea-windpipe- provides air from and to flow from the lungs for breathing uses. The trachea and larynx help prevent food going to me and Theo. The bronchi are two short branches located at the lower end of the trachea that carry air into the lungs. Last but not least, Theo and I’s jobs as lungs are to help oxygen from the air we breathe enter the red cells into the blood; the red cells then carry oxygen throughout the body. We are considered the hardest working organs in the whole entire body because we have to expel all the carbon dioxide in the body. Theo and I and also part of the circulatory system as well. The circulatory system transports the food nutrients and oxygen to the body cells, this helps the respiratory system but transporting nutrients to keep the lungs clean and healthy.
The respiratory does two very important things: it brings oxygen into the human body and helps get rid of carbon dioxide. If humans did not have oxygen in their bodies, their cells will not function properly. Oxygen is the most crucial thing for keeping humans alive because the body’s cells need it for energy and growth; with...
