The thirst mechansim stimulates your desire to drink fluids in response to increased salt in your blood or a decrease in___?
A. Salt in intracellular fluids

What should happen to Body temperature ,Hydration Levels ,Blood glucose levels and Oxygen levels 30 minutes after completion of marathon? Is this an example of negative or positive feedback? Explain reasons
If the oxygen level in the blood decreases, the brain sends a message to the lungs/diaphragm to breathe faster, which increases the levels of oxygen in the blood. This describes a negative or positive feedback loop.
