What will I learn?

  1. By the end of this session you will be able to:
  2. Describe the anatomical features and distribution of continuous capillaries, fenestrated capillaries and discontinuous capillaries/sinusoids in the body and relate these differences to function
  3. Define the term vasomotion and discuss how the capillary beds alter their tone
  4. Calculate the Starling forces on a capillary in the systemic circulation, and describe the differences in the brain, kidney, liver and lung
  5. Explain the contribution of the capillary to the flow and volume characteristics of the systemic circulation as a whole
