What is the Respiratory System?
The respiratory system is the organ system in which your intake of oxygen and expiration are monitored. Your respiratory system is a very crucial part of your body. Your Respiratory system consists of a multitude of organs. These organs are your mouth, nose, pharynx, larynx, trachea, lungs, and bronchioles. All of these seven organs play important roles for your body.
What is the main role of the Respiratory System?
The main role of the Respiratory System is to keep you breathing in oxygen, and breathing out carbon dioxide. The role of your nose and nasal cavity is to stop allergens from invading your lungs, these allergens are pollen and some more. There are small hair that line the nasal cavity, and they stop any allergens from entering into your system, and causing harm. The job of the oral cavity, or more commonly known as the mouth. The nose is the body’s primary source of breathing, but if for any reason there is a problem or obstruction in the naval cavity, your oral cavity will take charge of breathing. The pharynx is divided up into three main sections, these sections are the nasopharynx, oropharynx, laryngopharynx. The pharynx is between the nasal cavity, is the top end of the esophagus. Then comes the larynx, or also known as the voice box. The larynx is a small section that is adjoined with the end of the pharynx, known as the laryngopharynx. You have a pair of lungs (2) these lungs are used to contract when exhaled and expand when you inhale. The left lung is actually smaller than the right lung.
Overall, one of the 12 systems of the human anatomy is your Respiratory system. It is also an important system that keeps your body working/functioning properly. If your respiratory system does not function properly it could lead to death, considering you would not be able to breathe in the oxygen that is necessary for survival.
