Sodium is the principal cation in blood. If the blood concentration of sodium ions gets below normal:
1. blood volume increases and blood pressure decreases
2. water drains from the collecting duct
3. blood volume and blood pressure decrease
4. ADH secretion increases
RAAS is opposed by:
1. | ADH | 2. | renin |
3. | atrial natriuretic peptide | 4. | angiotensin II |
Mammals are:
1. osmoconformers.
2. hypotonic to their environment.
3. hypertonic to their environment.
4. osmoregulators.
