Mass Transport In Animals

• What are the roles of Haemoglobin in the lungs of a human?

  readily associates with oxygen & haemoglobin + oxygen --> oxyhaemoglobin
• What are the roles of Haemoglobin in humans in Respiratory Tissues?

  haemoglobin readily disassociates releasing oxygen & oxyhemoglobin --> haemoglobin + oxygen
• In gas exchange surfaces, what is the oxygen concentration?

  high

  low
• Does gas exchange surfaces have a high or low affinity for oxygen?

  high affinity
• What is the over all results for gas exchange surfaces?

  oxygen is attached
• In the respiring tissues, what is the oxygen concentration?

  low
• In the respiring tissues, what is the carbon dioxide concentration?

  high
• Does respiring tissues have a high or low affinity for oxygen ?

  low
• What is the results for respiring tissues?

  oxygen is released
