Respiration consists of transportation of oxygen from the atmosphere to the body tissues and the release and carriage of carbon dioxide formed in the tissues to the atmosphere.
The human respiratory system is a series of organs responsible for taking in oxygen and expelling carbon dioxide. We can list the primary organs of the respiratory system as nose, pharynx, larynx, trachea, bronchi, and lungs which carry out this exchange of gases as we breathe.

During inspiration air passes through respiratory passages due to the pressure differences formed in chest and trunk muscles. The ‘respiratory tract’ consists of these passageways and the lungs. We call the air passage from the nose through the larynx as the upper respiratory tract and the airway from trachea through the

The oxygen in the lungs spreads out into the blood and carbon dioxide in the blood spreads out into the lungs.
Internal respiration is the gasesous exchange in the body tissues. in contrast to these physiological processes, ventilation or breathing is a mechanical process that takes in and takes out air in to the and out pf the lungs. It consists of 2 steps: inspiration and expiration.

In human body respiratory system takes place at the same time but it’s practical to think as it includes number of steps.

To make sure that our respiratory system is healthy and working correctly or to find out simply what’s wrong(diagnosing lung diseases) we can do several tests as pulmonary function tests which measure the efficiency of our lungs in transferring oxygen into the blood and how well they inspire and expire the air.
There are several types of tests you can take to measure the function of your lungs: 1)Spirometry 2)Body Plethysmography 3)Lung diffusion capacity test 4)Bronchial provocation test 5) Exercise test

Lung function tests are safe and can take 15 to 30
