Question | Answer |
How carbon dioxide is transported? | 70% as Hydrogen ions in blood 23% combines with haemoglobin 7% dissolved in plasma (increases blood acidity) |
How oxygen is transported? | 97% carried by red blood cells (haemoglobin) 3% dissolved in plasma |
What are the two sites for gaseous exchange? | Air in alveoli of lungs and the blood Tissues/muscles of body and surrounding blood capillaries |
Where is myoglobin found? | In muscles it is used as a oxygen store and has a higher affinity than haemoglobin |
What causes the Bohr shift? | Increase in carbon dioxide and lactic acid production Increases acidity of blood Increase in blood and muscle temperature |
The Bohr shift causes the curve to move in which direction and why? | Curve moves to the right which allows more oxygen to be given up |
What is the arterial venous oxygen difference (a-VO2 diff)? | The difference in the oxygen content of the artery and the veins. It represents the amount of oxygen extracted by the muscles |
