What hormone regulates electrolyte and water balance?

There are three hormones that play key roles in regulating fluid and electrolyte balance: 1) antidiuretic hormone, released from the posterior pituitary; 2) aldosterone, secreted from the adrenal cortex; and 3) atrial natriuretic peptide, produced by the heart.
A.

What regulates water balance in the body?

When the body has excess water, thirst is suppressed. An interaction between the pituitary gland and the kidneys provides another mechanism. When the body is low in water, the pituitary gland (located at the base of the brain) secretes vasopressin (also called antidiuretic hormone) into the bloodstream.
  • How do we regulate water balance?

    The kidneys maintain our body's water balance by controlling the water concentration of blood plasma. The kidneys also control salt levels and the excretion of urea. Water that is not put back into the blood is excreted in our urine.
  • How do the kidneys regulate bone metabolism?

    The relationship between the kidney and bone is highly complex, and the kidney plays an important role in the regulation of bone development and metabolism. The kidney is the major organ involved in the regulation of calcium and phosphate homeostasis, which is essential for bone mineralization and development.
  • What hormone is produced by the kidneys?

    The kidneys secrete a variety of hormones, including erythropoietin, calcitriol, and renin. Erythropoietin is released in response to hypoxia (low levels of oxygen at tissue level) in the renal circulation. It stimulates erythropoiesis (production of red blood cells) in the bone marrow.
