Homeostasis  Homeostasis refers to maintaining internal stability within an organism and returning to a particular stable state after a fluctuation. Docsity.com Homeostasis  Changes to the internal environment come from: Metabolic activities require a supply of materials (oxygen, nutrients, salts, etc) that must be replenished.  Waste products are produced that must be expelled.  Docsity.com Homeostasis  Systems within an organism function in an integrated way to maintain a constant internal environment around a setpoint.  Small deviations in pH, temperature, osmotic pressure, glucose levels, & oxygen levels activate physiological mechanisms to return that variable to its setpoint.  Negative feedback Docsity.com Osmoregulation & Excretion  Osmoregulation regulates solute concentrations and balances the gain and loss of water.  Excretion gets rid of metabolic wastes. Docsity.com Osmosis  Cells require a balance between osmotic gain and lo..
