Document Summary
Ionic balance and osmotic regulation- chapters 27, 28, 29. Most vertebrates are osmoregulators: osmoregulator- an animal that maintains an approximately constant blood osmotic pressure even as the osmotic pressure of its environment varies. Most marine invertebrates are osmoconformers: osmoconformer- an aquatic animal that allows its blood osmotic pressure to match and vary with the environmental osmotic pressure. Hyposmotic regulator- an aquatic animal that maintains a blood osmotic pressure lower than the osmotic pressure of the water in which it lives: having a lower osmotic pressure, said of a solution in comparison to another. Hyperosmotic regulator- an aquatic animal hat maintains a blood osmotic pressure higher than the osmotic pressure of the water in which it lives: having a higher osmotic pressure, said of a solution in comparison to another. Isosmotic- having the same osmotic pressure, said of a solution in comparison to another.
