Give two ways we gain and lose water into our blood?
We gain water through drinking water and food with a hige water content. Lose: sweating and via the kidneys.

What part of our body senses the water concentration?
Hypothalamus.
4 of 7
What gland produces ADH
Pituitary gland.
5 of 7
What happens if the water concentration is too low
Hypothalamus detects low blood water concentration. Pituitary gland produces more ADH.Kidneys re-absorb more water into the blood. Less volume of urine. More concentrated urea produced
6 of 7
What happens if the water concentration is too high
Hypothalamus detects highblood water concentration. Pituitary gland produces less ADH.Kidneys re-absorb less water into the blood. Higher volume of urine. Less concentrated urea produced
