Respiratory System The respiratory system is the system that helps humans breathe and allow every single human to perform everyday tasks. As researchers say the respiratory system consists of organs. The organs that make up the system are the nose, nasal cavity, oral cavity, pharynx, larynx, trachea, bronchi, lungs, and muscles of the respiration. All these organs play a major role in the respiratory system. Scientists say every human breathe 20,000 times everyday. The respiratory system is a system that we all need for our body to function. It provides many wonderful help for everyone. As some can be happy with their respiratory system, many can also have problems

Another organ from the respiratory system is the oral cavity, in simpler terms the mouth. It is the external component of the respiratory system. The oral cavity lacks hair and mucus membranes to filter. Air can also be inhaled through the oral cavity if breathing through the nasal cavity is difficult. The pharynx is also part of the respiratory system and it is known as the throat in simpler words. It is a tube that leads to the stomach and lungs. The larynx has three main divisions the nasopharynx, oropharynx, and the laryngopharynx. The nasopharynx is where air passses, oropharynx is where food and air pass through, and lastly the laryngopharynx is also where the air and food pass through. Another part of the respiratory system is the larynx which is also known as the voice box. The larynx is anterior to the neck. It is connected to the upper part of the trachea and pharynx. It is formed by nine cartilages and eight muscles. Besides the larynx the trachea is also part of the system. The trachea is branch like tubes that carry oxygen to each individual body cell. It also transmit air from the larynx to the bronchioles. Added to trachea

One of the most common disease that affects the respiratory system is asthma. Asthma is a long duration disease that diminishes the airways of your lungs. It makes you have further difficulty breathing. The cause of the disease is not known. Researchers consider that some of the causes for asthma could be inherited or the environment could also have been something that affects your lungs and made it hard for you to breathe. Although the cause is not known yet, article of National Heart, Lung, and Blood Institute scientists hypothesize that the cause can be “... that our Western lifestyle—with its emphasis on hygiene and sanitation—has resulted in changes in our living conditions and an overall decline in infections in early childhood.” (NIH) The symptoms for asthma
