About the Course
In this lecture, Dr Helen Wallace (University of Liverpool) teaches us about the microscopic structures in our lungs and blood that allow for the exchange and transport of the two gases involved in respiration: oxygen and carbon dioxide. To do so, we: (i) introduce the alveoli and capillaries as the exchange surfaces that allow for oxygen and carbon dioxide to be exchanged, using Dalton’s Law to explain how diffusion is maintained in the desired direction, before then (ii) appreciating how oxygen and carbon dioxide are then transported in the lungs by haemoglobin.
