Question

Choose the correct answer from the alternatives given.
Body tissues obtain oxygen from oxyhaemoglobin because of its dissociation caused by:

• A. low oxygen concentration
• B. low concentration
• C. high concentration
• D. low and high concentration

Answer 1

The correct option is A low oxygen concentration

The body tissues have low oxygen concentration. The difference in partial pressure of oxygen between the tissue and the blood containing oxyhaemoglobin, caused by the low oxygen concentration in tissues results in dissociation of oxygen from haemoglobin and its movement into the oxygen deficit tissues. So, the correct option is 'low oxygen concentration'.
