22 Respiratory System The Respiratory System Respiratory System Consists of the respiratory and conducting zones Respiratory zone: Site of gas exchange Consists of bronchioles‚ alveolar ducts‚ and alveoli Respiratory System Conducting zone: Conduits for air to reach the sites of gas exchange Includes all other respiratory structures (e.g.‚ nose‚ nasal cavity‚ pharynx‚ trachea) Respiratory muscles – diaphragm and other muscles that promote ventilation Major Functions of the Respiratory

Respiratory System Respiration: The primary function of the respiratory system is to obtain oxygen gas for cell metabolism and remove carbon dioxide waste. Describe each of the following general processes of respiration. Ventilation- air is moved into and out of the lungs so the gases there are continuously changed and refreshed external respiration- oxygen diffuses from the lungs to the blood‚ and carbon dioxide diffuses from the blood to the lungs gas transport- oxygen is transported

The regions where the pain is coming from are where the sinuses are located. If the sinuses remain blocked for a long time‚ a secondary infection may result. This secondary infection is caused by bacteria‚ which are normally present within the respiratory tract. These bacteria multiply and cause a secondary infection in the paranasal

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

he Respiratory System Fig 4. Horse’s respiratory system The functions of the respiratory system are to provide the body with oxygen‚ to remove carbon dioxide from the body‚ to control temperature (breathing out warm air and breathing in cool air)‚ to eliminate water‚ to communicate (Voice production) and sensory input (Smell/ touch- nose hairs). The respiratory system consists of the nostrils‚ pharynx‚ larynx‚ Nostrils The nostrils expand to allow air to enter the respiratory system‚ hairs within

Air enters the nose by passing through the external nares or nostrils. The mucosa lining the nasal cavity‚ called the respiratory mucosa‚ warms the air as it flows pa Respiratory physiology The major function of the respiratory system is to supply the body with oxygen and to dispose of carbon dioxide. To do this‚ at least four distinct events‚ collectively called respiration‚ must occur: 1. Pulmonary ventilation Air must move into and out of the lungs so that the gases in
