The Various Organs Involved In The Respiratory System

Respiratory System The respiratory system is the bodies way to inhale and exhale air and diffuse oxygen. This system consists of several organs such as the trachea, lungs, larynx, pharynx, etc. All of these organs work together to help us breathe and are formed to their function. There is two different ways of respiration; external respiration which is the exchange of gases between the alveoli and the blood, and internal respiration which is the exchange of gases between the blood and tissue cells. The first step in the respiratory system is inhaling hair through the nasal cavity, which is the primary external opening for air flow. The nasal cavity is a hollow space within the nose that is lined with capillaries and cilla. The main function is to warm and filter air before it passes to the lungs, secrete mucus, and the cilia prevents debris from getting into the
It's a muscular funnel divided into three parts nasopharynx, oropharynx, and laryngopharynx (Respiratory System 4). It's main function is to pass inhaled air to the next parts in the respiratory tract from the nasal cavity, this is why it is shaped as a funnel so that the expected air is delivered properly. Next, before the air descends to the trachea it interacts which a flap of connective tissue called the epiglottis. The epiglottis closes the opening to the esophagus to prevent air passing into the stomach, then it closes the opening to the trachea during swallowing to prevent aspiration. It's shape as a flap is due it needing to cover different pathways. Thirdly, the air passes through the trachea, the trachea is a five inch, hollow tube surrounded by tough, flexible, C-shaped cartilage rings lined with cilia. It's main function is to allows air to pass from the pharynx into the lungs. The cartilage rings allows the trachea to remain open the entire time to provide a clear
