The respiratory system.
Through nose.
The function of the respiratory system is to provide the body with oxygen. Oxygen enters the body through the respiratory system and is carried in blood throughout the body.
It is carried in air droplets so enters through the airway and then into the lungs where it thrives on warm, damp environment.
During the respiratory system, oxygen travels through the respiratory tract and diffuses to the red blood cells from alveoli which receives carbon dioxide from the RBC's. The carbon dioxide comes from cells in the body. When the RBC's travel through the body to transfer oxygen to the cells it receives carbon dioxide. The carbon dioxide enters the alveoli and travels through the respiratory tract and is breathed out.
