• 1. Where in the circulatory system is the
  velocity of blood flow the lowest and why?
• 2. True or false R DP/Q.
• 3. Which of the following two copper tubes will
  have the higher flow rate and why?
• 4. All other factors being equal, will systemic
  arterial pressure be increased or decreased by
  catecholamine-mediated gill vasodilation in a
  rainbow trout?
• 5. Blood pressure in a capillary is 5 mmHg,
  plasma interstitial fluid colloid osmotic
  pressures are 20 18 mmHg, respectively, and
  interstitial fluid hydrostatic pressure is -1
  mmHg. Does net fluid flow occur, and if so, in
  what direction? Where might this capillary be
  found?
