Hey here is your answer,
breathing is the process in which air moves in and out of the lungs with the help of various respiratory organs. In other words, breathing is a simple give and take process. While breathing we take in oxygen-rich air from the atmosphere, in lieu of which, we give out air rich in carbon dioxide to the atmosphere. This is again utilized by the plants for photosynthesis. It is a continuous process and goes on all the time, throughout the life of an organism.
I hope it helps

The action of breathing in and out is due to the pressure inside the thorax in comparison to outside. This action is also known as external respiration.When we inhale the intercostal muscles and diaphragm contracts to expand the chest cavity. The diaphragm flattens and moves downwards an the intercostal muscle moves the ribcage upwards and out. This increase in size decreases the internal air pressure and so air from outside rushes into the lungs to equalise the pressure.
