WebAt the respiratory membrane, where the alveolar and capillary walls meet, gases move across the membranes, with oxygen entering the bloodstream and carbon dioxide exiting. It is through this mechanism that blood is oxygenated and carbon dioxide, the waste product of cellular respiration, is removed from the body. Gas Exchange WebTransport of oxygen. The majority of oxygen transported around the body is bound to the protein haemoglobin in red blood cells. Red blood cells are also known as erythrocytes; Each molecule of haemoglobin contains four haem groups, each able to bond with one molecule of oxygen . This means that each molecule of haemoglobin can carry four oxygen …
