Pathophysiology Hormone Balance

Question

1. Fill in the following table regarding the hormones involved in water and sodium balance. 

	Stimulus for Release	Effects of hormone
ADH
Aldosterone
Atrial natriuretic peptide

If anyone knows how to answer this, I'd really appreciate the help! Also, please ignore the two boxes to the side of the 'effects of hormone' section; I can't figure out how to remove them. Thanks.

Answer 1

ADH

Stimulus for release: high blood osmolarity (body state when we are low on water - makes sense because water is a main component of the solution)

Effects of hormone: increase water reabsorption by kidneys

Aldesterone

Stimulus for release: low blood pressure (another body state when we are low on water)

Effects of hormone: increase water reabsorption by kidneys BY increasing sodium reabsorption by kidneys (water follows sodium)

Atrial Natriuretic peptide (ANP)

Works antagonistically to aldesterone

Stimulus for release: stretched cells in atria of heart or more simply: too much water in circulation

Effects of hormone: promotes excretion (urination) of sodium and therefore water (water follows sodium)
