Human Respiratory System

According to biologists, Human Respiratory system is not simply the system of gaseous exchange; it encompasses a lot more, like transport of oxygen through blood, energy production by ETC (Electron Transport Chain) mechanism, and so on. It consists of the whole cycle of the intake, transfer, utilization and release or exhalation of respiratory gases.

Owing to rising levels of global air pollution, a number of severe respiratory diseases have evolved. To cope with such fatal maladies, you need to have a comprehensive understanding of the subject.

For this purpose, a detailed description of parts, functions, diseases and other related topics on “What is human respiratory system?” is given in the respective sections.

Different parts, like lungs, respiratory tract, pulmonary blood circulation, and accessory body organs of the respiratory system work with coordination to carry out a number of functions like a gaseous exchange, metabolism, cooling effect, and vocalization. The mechanism of its execution is involuntary with perfect check and balance on any of the processes to be undertaken. Respiration works at external as well as internal level and, at cellular stage, is further divided into aerobic and anaerobic types.
