The diaphragm moves down, and the intercostal muscles pull the ribs up and out. Both movements increase the volume of the chest cavity, thus reducing the pressure in the lungs. Air flows in from the outside to equalise the pressure.

Birds typically have nine air sacs: two cervical air sacs, two anterior thoracic air sacs, two posterior thoracic air sacs, two abdominal air sacs, and one interclavicular air sac. These air sacs help birds efficiently exchange gases during respiration and aid in maintaining their lightweight body structure for flight.
Two ways to reduce air pollution and improve air quality are to use public transportation or carpool to reduce vehicle emissions, and to support clean energy sources like solar and wind power to reduce reliance on fossil fuels.
don't hit your body that's how you can respect your body
The element CARBON enters the body in two NATURAL ways. First is through eating and drinking. Almost all food that we eat contain the element carbon. As the ingested food reaches the digestive system, food is broken down into smaller pieces up until the molecular level. Some molecules are taken into the circulation, while others are excreted down as feces. Second is by breathing. Certain air molecules contain carbon. One major air molecule is CARBON DIOXIDE. Some molecules are inhaled, but usually, CARBON DIOXIDE should be excreted from the body. Unnatural ways when CARBON could enter the body is by medical intervention, as in intravenous injections, surgery, etc.
