ILOs:
- Understand the principle of pressure and partial pressure of gases, including when they are dissolved in liquids.
- Describe the structure of haemoglobin and how it acts to transport oxygen from the lungs to the tissues.
- Explain the mechanisms which facilitate oxygen delivery to tissues, including effects of the position of the oxy-haemoglobin dissociation curve.
- Explain carbon dioxide transport in the blood.
- What is the basic transport and exchanges system of O2 and CO2 around the body?
- Recap - pressure and volume changes on inspiration and expiration
- Why are the lungs such a good gas exchange surface?
- Recap - what are the partial pressures of O2 and CO2 in the respiratory system?
- Recap - what is partial pressure?
- Recap - outline the pulmonary and systemic circuits and the movement of gases through them
- What are the partial pressures seen in the different circuits of O2 and CO2?
- Describe the alveolar capillary network and its properties
- How is oxygen transported in the body?
- Describe and explain the oxyhaemoglobin dissociation curve
- Define oxygen saturation and how do we measure this?
- How much CO2 is produced at rate and define the term "respiratory exchange ratio"
- How is CO2 transported in the blood stream?
- Outline the reaction to form bicarbonate and and the difference in this between the systemic and pulmonary capillaries
