Transcript of Respiratory System
Respiratory System functions
The respiratory system uses your mouth, nose, trachea, lungs and diaphragm.
How our system works with others.
This system helps the respiratory system by protecting the lungs. The circulatory system is very useful. This system transports the food nutrients, and oxygen to the body cells. It also delivers of carbon dioxide and waste products.

Supplies the body with O2 and CO2.
provides sound and speech making organs and tissue.
Primary function is to absorb oxygen and release carbon dioxide.
The Respiratory system affects the rest of the systems in the body.
You breathe with help of your diaphragm and other muscles in your chest.
These muscles literally change the space and pressure inside your body cavity to help with your breathing.
Diaphragm pulls down and makes room for your lungs to expand.
Lungs get bigger with air ad pushes the diaphragm relaxes and moves up, the cavity in your body gets smaller. Your muscles then squeeze your rib cage and your lungs begin to collapse as air is pushed out of your body.
The air humans breathe is Earth's atmosphere. The air we breathe out, however, is made up of approximately:
4.5% Carbon Dioxide
The respiratorys main function is to supply oxygen to all parts of your body. When we breathe we inhale oxygen and exhale carbon dioxide. The reason for the respiratory system doing this is to get oxygen to the blood.
The respiratory system helps the digestive system by giving oxygen to the digestive system.
The respiratory system has the lungs that deliver air to the muscles.
~Facts about the Respiratory System~
*The right lung is slightly larger than the left.
Hairs in the nose help to clean the air we breathe as well as warming it.
The highest recorded "sneeze speed" is 165 km per hour.
*The surface area of the lungs is roughly the same size as a tennis court.
*The capillaries in the lungs would extend 1,600 kilometers if placed end to end.
*We lose half a liter of water a day through breathing. This is the water vapor we see when we breathe onto glass.
*A person at rest usually breathes between 12 and 15 times a minute.
The breathing rate is faster in children and women than in men.
