The kidney in the fetal pig holds the urine, and has 2 main functions.==The kidneys regulate the body's fluid volume, mineral composition and acidity by excreting and reabsorbing water and inorganic electrolytes. This helps balance these substances (which include sodium, potassium, chloride, calcium, magnesium, sulfate, phosphate and hydrogen) in the body and keep their normal concentrations in the extracellular fluid.==Lying on top of the kidneys, is the Adrenal Gland.=
