Increased ADH, Increased Aldosterone, decreased ADH, and Decreased aldosterone. Help check my answers.?

Question

Match Column A with Colum B. My answers are posted, let me know if I am right or wrong.

Colume A:

1. causes production of dilute urine

My Answer: Increased ADH

2. results in increased sodium loss

My Answer: decreased aldosterone

3. causes the body to retain more potass.

My Answer: increased ADH

4. will cause water retention due to sodium movement

My Answer: decreased ADH

5. causes water reabsorption due to increased membrane permeability

My Answer: Increased ADH

6. Increases sodium reabsorbtion

My Answer: Increased aldosterone.

keep in mind all answers can have one or more answers. I just need to know if mine are right?

Answer 1

ADH stimulates water retention. Aldosterone stimulates sodium retention and potassium loss. Water will tend to follow the sodium. You really need to focus on these key facts.

1) should be decreased ADH. ADH is anti-diuretic hormone, so it has the opposite effect to a diuretic. It causes you to retain water, so increased ADH would give a more concentrated urine, decreased ADH gives dilute urine.

3) should be decreased aldosterone. Aldosterone promotes sodium reabsorption and potassium loss. So decreased aldosterone would give you low sodium and high potassium.

4) should be increased aldosterone. Increased aldosterone causes more retention of sodium. Water tends to follow where sodium goes.

5) correct - ADH stimulates water-permeable pores to open up in the renal collecting ducts, so more water gets reabsorbed from the filtrate.
