Respiratory System: Facts, Function and Diseases. The human respiratory system is a series of organs responsible for taking in oxygen and expelling carbon dioxide. The primary organs of the respiratory system are lungs, which carry out this exchange of gases as we breathe. Red blood cells collect the oxygen from the lungs and carry it to the parts of the body where it is needed, according to the American Lung Association.
How Cellular Respiration Works. The process of cellular respiration occurs in four stages: glycolysis; the transition stage; the Krebs cycle, also known as the citric acid cycle; and the electron transport chain. Each stage accomplishes different tasks. Glucose is the primary fuel used in glycolysis, the first stage of cellular respiration.
