All of the functions named are functions of the kidney.
The kidney is an important organ in the body and it has several functions which include:
I) Regulation of blood pressure. This is achieved by an increase in sodium and water consumption leading to an increase in extracellular fluid volume. This increases blood volume returning to the heart, increasing cardiac output, and it ends up increasing blood pressure.
II) Regulation of blood ph by adjusting the amounts reabsorbed and secreted, the kidneys balance the bloodstream’s pH.
III) Regulation of water and electrolyte concentrations in the blood by controlling sodium and water balance. When arteries pressure increases, the nephron reduces sodium and water reabsorption, increasing their excretion, while with a decrease in blood pressure, the nephron increases sodium and water reabsorption.
IV) Secretion of renin and erythropoietin . The kidney's endocrine function is carried out through the secretion of important hormones: renin, prostaglandins, erythropoietin, and calcitriol.
All of the above choices are functions of the kidney hence there is none that is not a function.
