Homeostasis (definition)
Temperature
-
Endotherm
organism generates heat within
-
Ectotherm
Organisms get heat from external sources
-
Types of Homeostasis
- Metabolic Production: as metabolism increases-heat increases
- Insulation: fur,feathers,blubber,fat layers
- Evaporative clothing: warm weather (sweat, pant, saliva)
- Behavioral: migration (birds)
- circulatory: dilate or constrict blood vessels
-
Homeostasis-water balance-kidneys
- A. Filteration: H20 and small molecules forced through capillary walls
- B. Reabsorption: Water, sugars, salts retun to blood
- C. Secretion: Substances forced back to urine track
- D. Excretion: Urine products passed to bladder
-
Solute-ADH-Water reabsorption
- Increased Solute:--ADH increases in blood- water reabsorption increases
- Decreased Solute:--ADH decreases in blood- water reabsorption decreases
