The oxygen–haemoglobin dissociation curve (or oxygen–hemoglobin dissociation curve) plots the proportion of haemoglobin in its saturated form on the vertical axis against the prevailing oxygen tension on the horizontal axis. The oxyhaemoglobin dissociation curve is an important tool for understanding ...
The given graph shows an oxygen dissociation curve for haemoglobin. Wher is the body will haemoglobin be saturated at the percentage shown at point 1,2 and 3 in graph ? ALeft ventriclePulmonary veinVena cava123 BLeft ventriclePulmonary veinVena cava213 CLeft ventriclePulmonary veinVena cava231 ...
the binding sites for oxygen are occupied till a sufficiently high PO2, all will comprise oxygen. A curve indicating the equilibrium binding of oxygen to blood is called the oxygen dissociation curve or oxygen saturation curve. It shows the relationship between the PO2 and the oxygen content tha...

Experimental studies in rodents have demonstrated that shifting the oxyhaemoglobin dissociation curve to the right (e.g. by increasing the 2,3 DPG level) increases the radiation response in rodent tumours whereas a left shift due to increasing CO-Hb reduces the effect of radiotherapy.doi:10.1080/...

THE important concept that the sigmoidal oxygen-dissociation curve of haemoglobin is a consequence of sub-unit exchange, and that the symmetrical dimer a]8 is thus to be regarded as the basic functional entity, is by now well established. An interesting demonstration of this mechanism is provided...
sustained activation of hypoxia signalling at a proper level is essential for the survival of cartilage cells. However, it is unclear how chondrocytes manage to maintain intracellular oxygen homeostasis. Here we provided evidence that, in response to hypoxia, chondrocytes produced large quantities of h...
Although a direct interaction between HpuA on meningococci and Hb was not detected using flow cytometry, the lipoprotein is required for the high-affinity interaction between HpuB and Hb, for meningococcal survival on Hb as a sole iron source and for efficient dissociation of Hb20,23. Growth ...
An increased concentration of 2,3-DPG will promote the offloading of oxygen to the tissues (i.e. a right shift of the oxygen Hb dissociation curve). Cardiac output increases during normovolaemic anaemia; the magnitude of this increase is closely related to the reduction in blood viscosity. ...
