What is the amount of O₂ delivered to the tissues per 100 ml of oxygenated blood under normal physiological conditions?

Options

  1. A2 ml
  2. B5 ml
  3. C10 ml
  4. D20 ml

Correct answer

B. 5 ml

Step-by-step solution

Partial pressure of CO2, hydrogen ion concentration and temperature are the other factors which can interfere with this binding. A sigmoid curve is obtained when percentage saturation of haemoglobin with O2 is plotted against the pO2. This curve is called the Oxygen dissociation curve and is highly useful in studying the effect of factors like pCO2, H+ concentration, etc., on binding of O2 with haemoglobin. In the alveoli, where there is high pO2, low pCO2, lesser H+ concentration and lower temperature, the factors
