Abstract
Once oxygen (O 2 ) that is present in atmosphere enters the respiratory tract, it reaches the alveoli and diffuses from the alveoli into the pulmonary blood. It is transported to the peripheral tissue capillaries almost entirely in combination with hemoglobin (Hb). The presence of Hb in red blood cells allows the blood to transport 30-100 times as much O 2 as could be transported in the form of dissolved O 2 in blood. This article is based on the published textbooks and articles that speak on the importance of O 2 and Hb; we have tried to put it into one place so that we can relate and apply the concepts.
