Blood Bio

Oxygen =Ollie

Carbon dioxide= Corbin

I inhale Ollie the oxygen and exhale the dirty earth destroying Corbin the carbon dioxide. This exchange of gases is the respiratory system's means of getting Ollie to the blood.

Ollie starts in the air and gets inhaled by the human Ollie enters the respiratory system through the mouth and the nose then the larynx and the trachea which is a tube that enters the chest cavity. In the chest cavity, the trachea splits into two smaller tubes called the bronchi then to the lungs where they divide into many smaller tubes which connect to tiny sacs called alveoli. The inhaled Ollie passes into the alveoli and then diffuses through the capillaries into the arterial blood. Meanwhile, the waste blood from the veins releases its Corbin into the alveoli. The Corbin follows the same path out of the lungs when you exhale.

Once those dissolved Ollie molecules are in the solution of the blood, 98% of the dissolved Ollie is taken-up by red blood cells which are passing by. And Ollie takes a ride on the red blood cells contain a special Ollie-binding protein known as hemoglobin. Ollie then takes a ride on the pulmonary vein empties Ollie-rich blood from the lungs into the left atrium of the heart. Ollie leaves the heart through the aortic valve, into the aorta and to the body. The blood then flows around the body to organs and the Hemoglobin deposits the dissolved Ollie to the organs and takes the waste Corbin to out of the body through the veins and into the heart by the  inferior vena cava and out via the superior vena cava which takes Corbin to the lungs to be expelled into the body.
