The kidneys are the main osmoregulatory organs in mammalian systems; they function to filter blood and maintain the dissolved ion concentrations of body fluids. They are made up internally of three distinct regions—the cortex, medulla, and pelvis.
The genetic code is being carried by the DNA molecules which are found in most organisms.

Both RNA and DNA are nucleic acids. DNA stores biological information. DNA is the backbone in resistance cleavage and is made from alternating sugar and phosphate.
