Question

What effect does salt have on your kidneys and water balance in your body?

Answer 1

There are a number of mineral salts namely: sodium, chloride,potassium and calcium. there are many others such as magnesium, these however are more involved in muscle contraction.

The kidney is the main regulator of the balance of salts. sodium and chloride salts (table salt) causes increased water reabsorbtion in the kindey tubules, leading to fluid expansion and an increase in blood pressure. to antagonise these effects, there is less anti-diuretic hormone released from the adrenal cortex (ADH). salts thus cause a increase in water reabsorbtion and and increase in water balance.

Answer 2

salt attaches to water, making it retain in the body.  if it is retained, it is not eliminated.  It also has to do with osmosis and diffusion

Answer 3

the short answer is that table salt is a combination of 2 ions of sodium and chloride and water follows these ions.  the kidneys regulate water balance by retaining or secreting sodium, which causes water to go with it.

Answer 4

Parathormone is a hormone produced by the parathyroid gland.

When the production of parathormone increases :-

Calcium salts are absorbed from the bones and added to blood.Consequently the bones become brittle.Moreover the Kidneys filter and excrete more calcium from the blood .This leads to stone formation in Kidney.
