What is the activity of kidneys controlled by?

Answer 1

kind if a vague q?

my answer.... hormones and blood content

for example:

when your dehydrated and your blood is lacking H2O your kidneys retain water....darker pee

when you drink Alcoholic Beverages it decreases amount of ADH hormone released....hence you pee more often. This is why you wake up dehydrated the next day. So even though your body needs the water its peeing out the lack of ADH prevent you from keeping it.

Answer 2

The composition of the blood, and the release of hormones control the activity of the kidney. The kidney in turn, releases the hormones renin, calcitriol and erythropoietin.
