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.

Where does carbon enter the body from?

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.
