Some Endocrine hormones have an effect on the respiratory passages. This can affect the amount of oxygen that the lungs absorb. Your lungs are part of a group of organs and tissues that all work together to help you breathe. This system is called the respiratory system. The main job of the respiratory system is to move fresh air into and get waste gases out of the body. The nose (naval canal) and the mouth (oral cavity) are two ways outside air enters the respiratory system. The hairs in the nose are apart of the air-cleansing system. The throat (pharynx) collects air from the nose and mouth and passes it to the trachea. The voice box (larynx) is where the vocal chords are located.
In those cases, for example, national standards can be used. The harmonised standards are developed by international standards organisations (CEC, ISO), transformed into European standards by the European standards organisations (CEN, CENELEC) and then transposed into national standards.
This is a list of published International Organization for Standardization (ISO) standards and other deliverables. For a complete and up-to-date list of all the ISO standards, see the ISO catalogue.The standards are protected by copyright and most of them must be purchased.However about 300 of the standards produced by ISO and IEC 's Joint Technical Committee 1 (JTC1) have been made freely and publicly available.This is an incomplete list that may never be able to satisfy particular standards for completeness.
