- 2. Identify organs of excretion and their roles.
- 3. Explain one mechanism of temperature control.
- 4. Describe how the body maintains water balance.
- 5. Consult your coach where necessary.
Evidence to Submit:
- • Excretory products and organs list.
- • Temperature control explanation.
- • Water balance notes.
Submission
Part C: Training Others
