-The human respiratory system allows one to obtain oxygen, eliminate carbon dioxide. -Your trachea (windpipe) splits up into two bronchi tubes. These two tubes keep splitting up and form your bronchiole -Breathing consists of two phases, inspiration and expiration -The Diaphragm is a muscle under lungs that controls breathing. -When you Inhale, the diaphragm contracts and moves down and air rushes in. -The diaphragm relaxes and moves up and air gets pushed out when you exhale. -Red blood cells pick up the oxygen and drop of carbon dioxide at the alveoli. -The alveolus is only one cell thick. -Covered with capillaries. -So oxygen and carbon dioxide can be exchanged. -When the air comes into your nose it gets filtered by tiny hairs and it is moistened by the mucus that is in your nose.
Covered with capillaries. So oxygen and carbon dioxide can be exchanged.

-Breathing consists of two phases, inspiration and expiration
-The Diaphragm is a muscle under lungs that controls breathing.
-When you Inhale, the diaphragm contracts and moves down and air rushes in.
-The diaphragm relaxes and moves up and air gets pushed out when you exhale.
-Red blood cells pick up the oxygen and drop of carbon dioxide at the alveoli.
-The alveolus is only one cell thick.
-Covered with capillaries.
-So oxygen and carbon dioxide can be exchanged.
-When the air comes into your nose it gets filtered by tiny hairs and it is moistened by the mucus that is in your nose.
