Place the following steps in the correct order when there is TOO LITTLE WATER IN THE BLOOD.
detected by hypothalamus
ADH is released by the pituitary gland
more water is reabsorbed into the blood from the kidney
small amount of concentrated urine is produced
water concentration in the blood returns to normal
Place the following steps in the correct order when there is TOO MUCH WATER IN THE BLOOD.
detected by hypothalamus
less ADH is released by the pituitary gland
less water is reabsorbed into the blood from the kidney
large amount of dilute urine is produced
water concentration in the blood returns to normal
Match the terms with their definitions
concentrated
more solute than solvent (water)
dilute
more solvent (water) than solute
ADH
water saving hormone
hypothalamus
detects amount of water in blood
pituitary gland
produces ADH
What happens to the level of ADH in the blood when there is TOO LITTLE WATER in the blood?
It decreases.
It increases.
There is no effect on the ADH level.
What happens to the level of ADH in the blood when there is TOO MUCH WATER in the blood?
It decreases.
It increases.
There is no effect on the ADH level.
Which body systems work together to regulate water in the body?
circulatory and respiratory
nervous and respiratory
nervous and urinary
urinary and respiratory

We determined that the marathon runner was suffering from...
hyponatremia
high blood pressure
low blood sugar
high body temperature
Hyponatremia is a condition where
the blood sodium (salt) level in the blood is lower than normal
the blood sodium (salt) level in the blood is higher than normal
blood pressure is higher than normal
blood pressure is lower than normal
Hyponatremia caused the marathon runner's brain cells to
gain too much water
lose too much water
gain too much sugar
lose too much sugar
A hormone is a chemical that
speeds up a chemical reaction
helps control body processes
contains genetic information
breaks down proteins
Water would (a) the cell by (b) .
The cell in the middle is in a/an (a) solution.
Which of the following solutions contains a higher concentration of solutes than the red blood cells?
Label the following cells by telling whether they are in a hypertonic, isotonic, or hypotonic environment.
Hypertonic
Isotonic
Hypotonic
If each dialysis bag has a glucose solution of 5.0 ml, what would happen in each of the following scenarios:
1) It is exposed to a 5.0 ml solution. This solution is (a) ; so the bag will stay normal.
2) It is exposed to a 10 ml solution. This solution is (b) ; so the bag will shrink.
3) It is exposed to a 3.5 ml solution. The solution is (c) ; so the bag will expand/blow up.
Label these parts of the excretory system
Which beaker has a cell that will swell?
Label the Solutions in each beaker. (not the cell)
Hypertonic
Hypotonic
Isotonic
