Larynx

The respiratory system is composed by a set of organs that are involved when breathing. The anatomy of the respiratory tract includes the nose, nasal cavity, pharynx, larynx, bronchi, lungs, alveoli and the diaphragm. There some organs of the respiratory system that are responsible for the process of breathing. The nose, pharynx, larynx, trachea, bronchi, and lungs permit the gas exchange to happen at the cellular level. The air enters through the nose and mouth and it goes into the lungs to…

It ensures that air passes into the trachea and consumable substances into the esophagus. Larynx- Located below the pharynx the larynx (voice box), aside from the ability of speech, acts as a form of defensive mechanism, any food passes the epiglottis into the trachea a strong cough reflex forces it back towards the pharynx. Trachea- The main respiratory function…

It sits posterior to the nasal and oral cavities and posterior to the larynx. It is divided into nasal, oral, and laryngeal parts.

The two nasal cavities condition the air to be received by the other areas of the respiratory tract. Owing…

cells excrete during this process. Upper Respiratory Tract Lower Respiratory Tract Nose Larynx Nasal Cavity Trachea Paranasal Sinuses Bronchial Tree Pharynx Lungs In the upper respiratory tract as air is breathed in and passes through the nasal cavity it is filtered, warmed, and moistened. This air passes through the nasopharynx, the oropharynx, and into the larynx through the epiglottis. The larynx, commonly called the voice box, is the passageway for air between the pharynx above…

Posterior vena cava: The Posterior vena cava is found in the lower body below the heart and extending to the heart. It is much smaller than the anterior vena cava. This vein brings nonoxygenated blood from the lower part of the body to the right atrium. The posterior vena cava is part of the circulatory system. Heart: The heart is a thick muscle located near the center of the chest between the lungs. It looks like a quenched fist, pinkish in color and is surrounded by the pericardium. Its…

and larynx. The pharynx serves, as an air and food passage but cannot be used for both purposes at the same time, otherwise choking would result. The air is also warmed and moistened further as it passes through the pharynx. The larynx is a short passage connecting the pharynx to the trachea and contains vocal chords. The larynx has a rigid wall and is composed mainly of muscle and cartilage, which help prevent collapse and obstruction of the airway. The larynx…

or both. Organic voice disorders are broken down even further into structural and neurogenic types. Structural voice disorders pertain to the a problem in the physical structure of the larynx, while neurogenic voice disorders are the result of a problem within the nervous system that interacts with the larynx. A common neurogenic voice disorder…

Smoking and the Respiratory System The respiration system is one of the prime systems in human body because its function is to deliver oxygen to the lungs in order to exchange gases. Many reasons can cause the function of the respiration system not to perform well and cause the diseases; smoking is one of the main reason and the most dangerous cause that can cause diseases in human body.
