Functions Of The Respiratory System

The respiration system is the process of supplying oxygen to the cells so that cells can metabolise energy. The main functions of the respiratory system are to maintain oxygen supply to cells, to remove water from the body, and to remove carbon dioxide from the body.

The respiratory and cardiovascular systems work together to supply oxygen to the body’s cells, remove carbon dioxide and regulate the Ph of the body’s fluids. This system of regulation is called homeostasis. (www.wiki.answers.com, 2013)

• Pulse Oximetry - Tests the percentage of oxygen in the blood. 95% or more is a normal level,

The respiratory system consists of the nose, mouth, pharynx, larynx, trachea, bronchi and lungs. These provide a passageway to allow air in and out of the body. Every cell in the body requires oxygen to survive.

The respiratory system is a complex organ structure of the human body anatomy, and the primary purpose of this system is to supply the blood with oxygen in order for the blood vessels to carry the precious gaseous element to all parts of the body to accomplish cell respiration. The respiratory system completes this important function of breathing throughout inspiration. In the breathing process inhaling oxygen is essential for cells to metabolize nutrients and carry out some other tasks, but it must occur simultaneously with exhaling when the carbon dioxide is excreted, this exchange of gases is the respiratory system's means of getting oxygen to the blood (McGowan, Jefferies & Turley, 2004).

The Respiratory system is an integrated system of organs involved in the intake and exchange of oxygen and carbon dioxide between an organism and the environment. Your Respiratory system is made up of the organs in your body that help you breathe. The Respiratory system is the system of the body that deals with breathing. The trachea is a wind pipe. The trachea is a pipe shaped by rings of cartillage. A Bronchi are two tubes that carry air into the lungs. The Respiratory system consistes of many different organs. The organs are the lungs, trachea, bronchi, alveoli, diaphragm, nose, mouth, and pharynx. In the Respiratory system the right lung is larger and has more lobes that the left lung becuase the heart is normally located on the left side, and takes up space where the lung would had been. The functions of the Respiratory system is to supply the blood with oxygen in order for the blood to deliver oxygen to all parts of the body. The Respiratory system is also used for the of exchange gases. The importance of the Respiratory system is that it allows for the exchange of gases; meaning carbon dioxide and oxygen. These gas exchanges occur in the alveoli's and the capillaries. This gas exchange of gases is the Respiratory system's means of getting oxygen to the blood. The goal of breathing is to

Oxygen enters the respiratory system through the mouth and the nose. The oxygen then passes through the larynx (where speech sounds are produced) and the trachea which is a tube that enters the chest cavity. In the chest cavity, the trachea splits into two smaller tubes called the bronchi. Each bronchus then divides

The nose has two nostrils that provide an opening through which air can enter and leave the nasal cavity. There are many hairs in the opening to help prevent the entry of large particles that are in the air.

The respiratory system consists of the lungs and air passages. The system functions to bring in air and extract oxygen and remove carbon dioxide*. The body can hold 4 to 6 minutes worth of oxygen so the respiratory system must work at all times to prevent death. There are multiple parts to the respiratory system for example, the nose has nostrils or nares. It contains a nasal septum which divides the nose into hollow spaces called nasal cavities. The nose filters the air with the mucus produced. Also located in the nose are the olfactory receptors, and nasolacrimal ducts. The sinuses which are resonating chambers of cavities located in the skull. A larger part of the respiratory system is the pharynx also known as the throat. It is located directly behind the nasal area, divided into three parts; nasopharynx(upper portion), Oropharynx(middle portion), Laryngopharynx (lower portion). The larynx also known as the “voice box” located between the trachea and pharynx. Trachea also known as the windpipe extends from the larynx to the center of the chest; its functions to carry air between the pharynx and bronchi. The bronchi function to carry air to the lungs. The right bronchus is more vertical, shorter, and wider compared to the left.Bronchi continue to branch off into smaller bronchioles, the smallest is called terminal bronchioles which deliver air to the alveoli. 500 million alveoli, which have a rich network of capillaries needed for exchange of oxygen and CO2( taken place

Consist of the nasal passage, pharynx, esophagus, larynx, trachea, lungs, diaphragm, bronchi, and pulmonary artery and vein.

The main organs of the respiratory system are the lungs – they are the location where the gas exchange between oxygen and carbon dioxide takes place. The lungs therefore expand when you breathe in, and retract when you breathe out. This is done through the diaphragm – a sheet of muscle that is positioned under the lungs. As one inhales, their diaphragm contracts and moves itself downward, increasing the space for your lungs to expand to. The ribs also move to enlarge the possible area the lungs can expand to. This pressure causes air to be sucked through the body to the lungs. When one exhales, the opposite takes place – the diaphragm moves upwards and returns to normal, allowing the process to happen again.

The mouth is the secondary external opening for the respiratory tract. It does not have the hair and sticky mucus that filter air passing through the nasal cavity but its shorter distance and bigger space allows more air to quickly enter the body.

The human body comprises of two respiratory sponges called lungs. The left lung is slightly smaller than the right as it makes room for placement of the heart. Due to this slightly smaller size, it only contains two lobes whereas the right lung has 3 lobes. Both lungs are host to the network of air sacs or alveoli which transport the air from the outside environment to the external and internal respiration processes.

To deliver oxygen to the body, air is breathed in through the nose, mouth or both.

This concept is taken from Block 4, Module 6 which is entitled as ‘Assessment of respiratory system’. The respiratory system comprises of different organs used in respiration. Respiration involves inhalation and exchange of oxygen and carbondioxide between living organisms and the environment. The organs of respiration include; the nose, pharynx, larynx, trachea, 2 bronchi, bronchioles, 2 lungs and muscles of breathing (the intercostal muscles and the diaphragm).
