What is the amount of oxygen supplied by 100 ml of blood in tissues?
Correct answer: B. 19.6 ml/100 ml of blood
- A. 15 ml/100 ml of blood
- B. 19.6 ml/100 ml of blood
- C. 20.1 ml/100 ml of blood
- D. 200 ml/100 ml of blood
Explanation
In 100 ml of blood, there is about 15 g of Hb, so 100 ml of blood has the capacity to bind 19.6ml of oxygen.

About Gaseous Exchange in Lungs
Gaseous exchange in the lungs occurs across the thin, moist alveolar and capillary surfaces, where oxygen and carbon dioxide diffuse down partial pressure gradients. The topic covers alveolar adaptations, ventilation, the role of haemoglobin in oxygen transport, carbon dioxide carriage, and the difference between external gas exchange and cellular respiration.
