Describe, step by step, the journey of oxygen through the body and carbon dioxide out of the body.
Air is inhaled through the nose, filtered in the trachea, and distributed through the lungs by bronchioles. It is then sent to the alveoli where capillaries release carbon dioxide from blood cells and pick up oxygen. Oxygenated blood is sent back to the heart through the pulmonary veins and pumped into the aorta to be sent to capillaries throughout the body. In these capillaries it is exchanged with cells and carbon dioxide is picked up. Carbon dioxide is taken back to the heart through veins and the vena cava. It is then pumped up through the pulmonary artery to the capillaries in the alveoli where it is exchanged for more oxygen and exhaled from the body.
