WebEach hemoglobin molecule contains four iron-containing heme molecules, and because of this, one hemoglobin molecule is capable of carrying up to four molecules of oxygen. As oxygen diffuses across the respiratory membrane from the alveolus to the capillary, it also diffuses into the red blood cell and is bound by hemoglobin. WebHemoglobin is loaded with oxygen as it passes through the pulmonary capillaries and is then transported to the peripheral tissues where the oxygen is unloaded. The primary factor determining whether oxygen is loaded or unloaded onto hemoglobin is the surrounding partial pressure of oxygen. ear infection and tinnitus
