1. Briefly compare endocrine signaling with synaptictransmission.
2. Compare parasympathetic vs. sympathetic control of vascularsmooth muscle. Note similarities and differences including theorganization of pathways, pre- and post-ganglionicneurotransmitters, etc.
3. Compare blood flow (perfusion) and air/water flow(ventilation) in fish gills, frog lungs, bird lungs and mammalianlungs. Consider how terms of the Fick Diffusion Equation (writeout) are manifest in the design of the exchange surfaces.
4. What forces contribute to movement of solutes from acapillary lumen into tissue spaces and return from tissue spaces tothe capillary lumen?
