Question

The oxygen content of arterial blood is typically...

Select one:

a. 40 mlO₂/dl

b. 100 mlO₂/dl

c. 15 mlO₂/dl

d. 20 mlO₂/dl

e. 5mlO₂/dl

Answer 1

Ans- d. 20 ml O2/ dl

The main function of circulating blood is to deliver oxygen and other nutrients to tissues and remove products of metabolism. Oxygen delivery is dependent on oxygen availability , the ability of arterial blood to transport oxygen and tissue perfusion. The oxygen content of systemic arterial blood depends on several factors as partial pressure of inspired oxygen, the adequacy of ventilation and gas exchange, the concentration of haemoglobin and the affinity of the haemo­globin molecule for oxygen. The oxygen content of arterial blood in normal person is 20 ml/dl.
