Essays on Respiratory System
The respiratory system is an important organ system in the human body. It is responsible for taking in oxygen and releasing carbon dioxide. This process, known as respiration, is a vital part of staying alive. The respiratory system begins at the nose and mouth, where air enters the body through inhalation. From there it passes down the trachea (windpipe) to the lungs, which are filled with millions of tiny sacs called alveoli that allow oxygen to enter into blood vessels and carbon dioxide to exit into exhaled air. The primary organs involved in this process are the nasal cavity, pharynx, larynx, trachea, bronchi and lungs. In addition to these main parts of the respiratory system there are also several accessory organs such as diaphragm muscles that assist with breathing movements and glands such as mucus-producing cells that help keep your airways clear from germs or irritants. When you breathe in (inhale), your diaphragm contracts while your rib cage expands outward allowing more room for incoming oxygenated air; when you breathe out (exhale), your diaphragm relaxes while your rib cage contracts inward pushing out any residual unwanted carbon dioxide back into the atmosphere. Through this cycle of inhalation and exhalation we can maintain healthy levels of oxygen within our bodies necessary for proper functioning. In addition to assisting us with regular bodily functions like digestion and circulation, a healthy respiratory system helps protect us against infection by filtering out bacteria or other pathogens present in inhaled air before they have a chance to reach vulnerable areas around our heart and lungs via our bloodstreams ” hence why it’s important not just to get plenty of restful sleep but also stay away from secondhand smoke or heavily polluted environments.
