  1. invaginations of the body surface

    intimately associated with the circulatory system

    have a dense network of capillaries under a epithelium
  2. cooperativity
  3. 4 O2 molecules
  4. evaginations of the body wall
  5. circulatory system

    diffusion of gases down concentration gradients

    metabolic consumption
  1. a lungs
  2. b what are gills
  3. c how many molecules of O2 can bind to one hemoglon
  4. d hemoglobin exhibit the property of what
  5. e diffusion gradients (oxygen & carbon dioxide) are maintained by

5 Multiple Choice Questions

  1. what animal has this:

    cutanous respiration & or gills or simple lungs
  2. what kind of tissues are the alveoili made of
  3. water & blood flow in what direction in gas exchange
  4. which animals rely on lungs exclusively
  5. movement of respiration media across the gills w/out any extra energy investment

5 True/False Questions

  1. uncoupling of circulatory & respiratory systems

    decrease in water loss (in open circulatory system)
    how is respiration controlled


  2. where additional O2 is released from hemoglobin at lower pH as a result of greater CO2 production.

    This is used to support more cellular respiration
    what is the Bohr shift


  3. 300at what percentage of saturation does the hemoglobin bind to molecules


  4. medulla oblongata & ponssystem of sacs with one way flow system maximizes exchange


  5. concentration of waterrelatively low metabolic rates (aquatics have this)

    low adaptations to maximize exchange
