Question Answer Link
What are the problems if body water levels drop too low?
  • Inadequate perfusion due to low blood volume
  • A build up of waste products due to insufficient urine volume
  • Increased solute concentrations affect cell function
  • Inability to sweat and control body temperature
  • Death
 Link
What are the problems if body water levels get too great?
  • Oedema
  • Increased blood volume and therefore pressure could damage the CVS
  • A decrease in solute concentrations disrupt normal cell function
 Link
If you take a fat and a thin cow, which will have the most body water and why? The thin cow as adipose tissue contains little water Link
Metabolic water is derived from which reaction? The oxidation of hydrogen Link
What is "insensible water loss"? Insensible water loss is water loss which cannot be sensed by the individual and tends to be a response to thermoregulation rather than being a regulated process of water homeostasis Link
As milk yield increases how does this effect water intake?
  • A - Water intake increases more than milk yield
  • B - Increases in water intake match milk production litre for litre
  • C - Water intake increases but not as much as milk yield
  • A
 Link
What are aquaporins?
  • Family of membrane channel proteins
  • Over a dozen homologous water transporting proteins make up this family in mammals
  • Allow rapid transport of substances across membranes
 Link
AQP2 is inserted into the membrane of which cells to increase water reabsorption? Principal cells of the collecting duct Link
Which hormone influences this insertion? ADH Link
What are the two differant types of nephron called?
  • Juxtamedullary
  • Cortical
 Link
