Respiration is the process of releasing energy from glucose molecules, whereas breathing is the physical act of inhaling oxygen and exhaling carbon dioxide.
Aerobic respiration occurs in the presence of oxygen and involves the complete breakdown of glucose into carbon dioxide and water, releasing energy in the form of ATP. The overall equation for aerobic respiration is: C6H12O6 + 6O2 → 6CO2 + 6H2O + energy (ATP)
Anaerobic respiration occurs in the absence of oxygen and involves the partial breakdown of glucose into lactic acid or ethanol and carbon dioxide, releasing energy. The overall equation for anaerobic respiration in humans is: C6H12O6 → 2C3H6O3 (lactic acid) + energy (ATP)

I) The blood vessel that brings oxygenated blood to the human heart is the pulmonary vein. II) The left atrium receives oxygenated blood from the pulmonary vein. III) Oxygenated blood from the left atrium is pumped into the left ventricle, which then contracts to send the oxygenated blood to all parts of the body through the systemic circulation.
