Document Summary
Organismal physiology: lecture 20 water and salt physiology in their. Have a problem; we are losing animal diversity and species, as well we are on the brink of losing the old ecosystems cause of rapid change in climate. Other issue is birds large loss, soon to be a huge problem. Lota of water; defend osmolality, water in cells can easily and quickly dehydrate and threaten your life in hot environment. Can"t drink salty water can"t extract the h20 the salt concentration will make us dehydrate faster. Ratio of all ions in salt water (eg take on kg) will approximately show 34-36 grams of salt in that water. Interesting thing about salt water is the consistency or salinity of the water is exactly the same (usually constant in every ocean) the ion ratio composition is the same. Very different from fresh water mimimum ion concentration, fresh water is typically below 0. 5/kg important to know to understand difference between both.
