The respiratory system is a collection of organs and tissues that assist in breathing. Your airways, lungs, and blood arteries are all part of it. The respiratory system includes the muscles that power your lungs. These components work together to transport oxygen throughout the body while also removing waste gases such as carbon dioxide.
The lungs and respiratory system allow oxygen from the air to enter the body while simultaneously allowing carbon dioxide from the air to leave the body. The diaphragm travels lower into the abdomen as you breathe in, while the rib muscles pull the ribs upward and outward.
