Dehydration

Question 1

what are the effects of dehydration

Answer 1

1. high osmolarity of the plasma

2. low BP and low BV

Question 2

are the following hormones released or not during dehydration; why

1. ADH
2. aldosterone
3. angiotensin
4. naturetic peptides

Answer 2

1. ADH; yes b/c it increased BV + BP and lowers osmolarity
2. aldosterone; no b/c osmolarity is already high
3. angiotensin; yes b/c it has many effects to increase BV + BP
4. naturetic peptides; no b/c we already have low BP + BV and it will block aldosterone
