Describe how Starling forces determine fluid flux within the pulmonary capillary bed.
The equations for nett fluid flux and for nett filtration pressure were incorrect in many answers.
Better answers presented the equations and discussed each of the elements as relevant to the
pulmonary capillary bed, including difference from systemic capillary beds.
Mention of the role of lymphatics and of the effect of surfactant, left atrial pressure, gravity and
posture gained marks, also.
