WebThe oxyhemoglobin dissociation curve reflects the relationship between the oxygen saturation of hemoglobin and the partial pressure of arterial oxygen. It can shift depending on various factors, but if we look at the reasons behind how the body delivers oxygen to the tissues, we can discern the different triggers. WebSummary. Haemoglobin is found in red blood cells and carries oxygen efficiently from the lungs to the tissues in body. It also aids in transporting hydrogen ions and carbon dioxide back to the lungs. Haemoglobin is capable of binding to oxygen (O 2) and gaseous nitric oxide (NO). When red blood cells pass along the capillary beds of the gills ...
