Document Summary
Slide 3: water: is an inorganic compound that makes up mostly everything in the body, It forms the fluid that surrounds the tissue determines the volume of cells and tissues. Enzymes depends on the degree of hydration. Slide 4: osmoconformers: internal levels of ions and water fluctuation with different environmental changes, osmoregulators: maintaining the levels of ions and fluids as the environment changes. Slide 5: obligatory osmotic changes: change in the body due to environmental changes that the a(cid:374)i(cid:373)al does(cid:374)"t ha(cid:448)e a (cid:272)o(cid:374)trol to, controlled osmotic changes: changes in the body osmoregulation due to changes in the environment. These changes the animal has control on them. Usually done to overcome the obligate osmotic change. Slide 6-10: factors leading to obligatory osmotic exchanges (animal has no control on these) 1) gradients between internal and external mediums. Example: frogs in freshwater take up water from the medium due to their high ionic concentration compared to the external medium (hypoosmotic medium)
