1. What is the physiological water distribution?Approximately two-thirds of the body's water is intracellular, and one-third is extracellular
2. What is the antidiuretic hormone (ADH)?Also known as vasopressin, ADH regulates water reabsorption in the kidneys
3. Why do we feel thirsty?When we lose water, the brain notices the fluid is too salty and tells us to drink. This helps the kidneys keep the right amount of water inside.
4. How does water help us think and play?Water carries food, oxygen, and signals to our brain, so staying hydrated keeps us focused and gives us energy for games.
