Question

Which is not a function of the kidneys? they regulate osmolarity of the body fluids. they help control blood pressure. they remove metabolic wastes from the blood. they regulate red blood cell production. they regulate plasma protein levels in the blood?

Answer 1

The answer is they regulate plasma protein levels in the blood. Blood proteins do not pass into the glomerular filtrate during filtration at the glomerulus. Therefore, kidneys have no role in their regulation. Kidneys influence RBCs production by producing erythropoietin which targets the erythroid colony-forming cell. Osmolarity is regulated by regulating re-absorption of water and sodium ions. Kidneys control blood pressure by regulating blood volume.

Answer 2

The functions of the kidneys include: regulating osmolarity of the body fluids; helping control our blood pressure; removing metabolic wastes from the blood; and regulating red blood cell production. Regulating plasma protein levels in the blood, however, is not a function of the kidney. Healthy kidneys do not allow the proteins to pass through their filters Therefore, kidneys have no role in their regulation.
