The kidneys
The amount of iron in the body is primarily regulated by the hormone hepcidin, which helps control the absorption of iron from the intestines and the release of iron from storage in the body. Hepcidin levels are influenced by factors such as iron levels in the blood, the body's need for iron, and inflammation.

The kidneys can either re-absorb water back into the body or excrete more water outside of the body. This is regulated by hormones such as ADH and aldosterone.
Antidiuretic hormone (ADH) is regulated by the pituitary gland. The anitidiuretic hormone maintains blood pressure and controls incoming water through the kidneys

GFR is regulated by having the technicians doing the tests be educated in cleanliness and proper hygiene. The person who analyzes the test is also trained how to analyze the blood. GFR is the Glomerular Filtration Rate. It measures how well the kidneys are processing waste.
The pH of the blood is regulated by short term changes mediated by altering the rate of respiration and on the longer term by filtering of the blood in the kidneys.
gold and copper and zinc and sliver and iron, it can be any of those.
Symptoms of sodium imbalances are primarily manifested through alterations in the kidneys. Changes in sodium levels can affect the body's ability to maintain fluid balance and blood pressure, which are regulated by the kidneys.
Water excretion is regulated by the kidneys through a hormone called antidiuretic hormone (ADH), also known as vasopressin. ADH acts on the kidneys to increase water reabsorption, leading to concentrated urine and decreased water excretion. Other hormones, such as aldosterone and atrial natriuretic peptide (ANP), also play a role in regulating water excretion by affecting salt and water balance in the body.
