Question

When absorption of electrolyte ions is functioning normally, mineral balance is achieved through the action of

options: the small and large intestine.

the kidneys and the sweat glands.

the kidney and the bladder.

thyroxine and cortisol.

Answer 1

Answer should be C) kidneys and bladder.

Mineral balance is defined as a state of equilibrium or balance in between the rate of ion absorption anf rate of ion excretion.

It is evident that , ions are absorbed by small and large intestine from the food we consume and the excess of ions are excreted out by kidneys.

So when ion absorption is functioning normally, kidneys and bladder will have to act normally to acheive mineral balance by formation of urine and excretion if excess ions from body.

If question is asking what is the keeping ion absorption in balance then answer should be C) the kidney and bladder.

But if question is asking what structure has to function normally to acheive ion absorption to maintain mineral balance, then answer will be small and large intestine as they are the major sites for absorption of nutrients and minerals.
