- Homeostasis
- Glucoregulat-ion
- Pancreas + Liver
- Low sugar
- Decrease in Glucagon
- Glycagon Converts to Glucose
- Exits Liver
- Increase in blood sugar levels
- Exits Liver
- Glycagon Converts to Glucose
- Decrease in Glucagon
- Low sugar
- Diabetes
- Glucose in urine
- Kidney unable to reabsorb all glucose
- Require insulin injections
- Glucose in urine
- Pancreas + Liver
- Osmoregulati-on
- Water
- Too little
- Brain - increase in ADH
- Urine - increase water in blood
- Too much
- Brain decreases ADH
- Increase in urine
- Decrease of water in blood
- Brain decreases ADH
- Too little
- Brain + Kidneys
- Into Bladder (via Urea)
- Ions
- Urea
- water
- Into kidneys (via blood)
- Water
- Ions
- Glucose
- Urea
- Out of kidneys (via blood)
- Water
- Ions
- Glucose
- Kidney failure
- Dialysis
- Fluid and ppm (partially permeble membrane)
- (osmosis and diffusion)
- Dialysis
- Into Bladder (via Urea)
- Water
- Thermoregul-ation
- Brain
- If temp too low
- Shiver
- Muscles contract
- More respiration
- More heat
- More respiration
- Muscles contract
- Vaso constriction of blood vessels to skin
- Less blood flow
- decrease heat loss from blood
- Less blood flow
- Shiver
- If temp too high
- Increase in sweating
- Skin cools as water evaporates
- Vasodilation of blood vessels to skin
- Blood nearer skin for diffusion
- Increase heat loss from radiation
- Blood nearer skin for diffusion
- Increase in sweating
- If temp too low
- Brain
- Glucoregulat-ion
