3. there is an exchange between kinetic and potential energy
4. the largest drop in energy occurs at the level of the precupillary sphincters
5. the higher resistance in smaller calibre vessels corresponds to greater energy losses
- d. the largest drop in energy occurs at the level of the precupillary sphincters
