UNIT 17 The Kidney and Osmoregulation
Essential idea:
- All animals excrete nitrogenous waste products and some animals also balance water and solute concentrations.
- How do animals control the amount of water in their bodies?
- Why is it common for nitrogenous waste to be excreted by the same organ that regulates water?
- What are the two roles of the kidney (tubules)?
- What are the different parts of the kidney called?
- What is the function of each part?
- How are the tubules adapted to aid conservation of water in animals living in dry environments?
- Nitrogenous waste is excreted as different chemicals in different animals.
- What are the chemicals and why are there such differences?

Osmoregulation |
Do you remember osmosis? Recap and learn about osmoconformers using this simple ppt 2. Osmoregulation and osmoconformers Using the worksheet annotate the simple jellyfish diagram - to illustrate this example of osmoconforming marine invertebrates: 3. Osmoregulation worksheet Watch this video showing the paramecium:Annotate the diagram illustrating how this single celled Paramecium, which lives in fresh water, copes with constant inward osmosis from the surrounding water into its cytoplasm. 4.
