AS Partial pressure

All aspects of partial pressures

QuestionAnswer
Carbon dioxide is transported? 70% as Hydrogen ions in blood 23% combines with haemoglobin 7% dissolved in plasma (increases blood acidity)
Oxygen is transported? 97% carried by red blood cells (haemoglobin) 3% dissolved in plasma
What are structures at alveoli that help diffusion Thin alveolar membrane (small distance for gases to travel Numerous alveoli Vast capillary network Diameter of capillaries smaller than blood cell therefore slow blood flow
What is Partial pressure Pressure that is exerted by an individual gas when it is in a mixture of gases
Why and how do gases move? From areas of high partial pressure to a lower partial pressure via diffusion
Where are the two sites for gaseous exchange? Air in alveoli of lungs and the blood Tissues/muscles of body and surrounding blood capillaries
What is a pressure (diffusion) gradient? Difference in high and low partial pressure. The greater the gradient the greater the diffusion
Where is blood pO2 is highest? In the arteries
Where is blood pCO2 is highest? In veins leading away from the working muscles
