The importance of the Respiratory system is quite obvious given that as human beings we need this system to help us with our most fatal tasks of breathing. Although the importance is assumed and acknowledged, many do not really get the whole concept of the Respiratory system. For example, how it works? Why it works? And what all is involved. These questions and others will be strategically answered in the following work.

The Respiratory System delivers oxygen to the body and takes the carbon dioxide away. This system is made up of organs that allow you the ability to breath. These organs are the Lungs, Trachea, Bronchi, and the Diaphragm. The lungs are considered the main organ of the system. It takes in the oxygen and releases the carbon dioxide. How this happens is the red blood cells take oxygen to the body and take the carbon dioxide to the lungs, and this allows us to breath. The trachea cleans the air that we breathe in, it works as a filter. This filter flows into the bronchi, which is the next organ. The bronchi carries the air into the lungs, this is the two tubes that are coming of the trachea. The diaphragm is where everything begins, your breathing starts here. This is the muscle in this system used when breathing. Respiratory Homoeostasis is the movement of blood gas composition. If anything moves out the homeostatic range the change is noticed by the chemoreceptor, which is a sense organ. This then alerts the repertory response that a change in the alveolar ventilation. This happens by a lot of oxygen pressure put in the alveoli either by oxygen-enriched gas mixtures or improving the alveoli ventilation. (Clancy J., McVicar A.) The interaction with the respiratory system and the organ system is vital. Communication allows our body’s to adjust the function of each organ according to the needs of the whole body. Oxygen is most important as it keeps us alive as body cells need it for energy and growth. With each inhalation, air fills a large portion of millions of alveoli; this is called diffusion, oxygen then moves from the alveoli to blood through capillaries (Campbell & Reece, 2008). The hemoglobin in red blood cells then picks up the oxygen in the bloodstream then flows back to the heart, which in turn pumps it through arteries to tissues throughout the body. With this function alone, it is vital to the human body, the respiratory system controls the oxygen intake and carbon dioxide release and it feeds the blood cells in our bodies for the other organs to function. Without this we would not produce oxygen and keep the blood flow moving. The respiratory system is comprised of organs that all work together for the common good, our goal is to insure that we breathe. For without this, we couldn’t. I don’t think we can say which organ has the most important part. For without one, the others wouldn’t work. Our respiratory system starts with the nose. In the nose there is a substance which is called mucus. The mucus and the tiny hairs that are located in the nose trap the dust and germs. If these passages would become clogged, you most likely will sneeze, thus opening up once again the nasal passages. After the air travels through the nose, it will start to warm. This warm air, which is also now clean, will then travel down to a tube which is called the trachea. Located at the top of this or the beginning of this would be the larynx. The larynx is also called the voice box. The muscle walls of this are comprised of cartridge and of muscles. At the bottom of the trachea there are two tubes which are called the bronchial tubes. These tubes will then deposit the air into the lungs. The lungs are comprised of something called bronchioles. These will then lead into the end into the tiny sacs of air which are called alveoli. The airs will then pass through these and pass thru the blood vessels finally ending up in the blood stream. While all of this...
