Systems of the Human Body!

The Respiratory System

The respiratory system is in charge of breathing. Through the nose or mouth we obtain oxygen, which passes through the pharynx, larynx, and trachea to the lungs.

In the lungs, oxygen is exchanged for carbon dioxide.

The red blood cells are responsible for carrying oxygen to all parts of the body.

Carbon dioxide is a harmful substance that we have to eliminate from our body by going back out the way we came in, from the lungs to the nose or mouth.

Carbon dioxide is eliminated from the body without us even realizing it.
