The urinary system is made up of the kidneys, ureters, urinary bladder, and urethra, which perform the functions of filtration, production, and excretion of urine; remove waste and regulate the volume and composition of the blood; help maintain the acid-base balance of body fluids, supports the body's mineral balance, and helps regulate red blood cell production. Diet and physical exercise influence people's quality of life. Kidney disease (CKD) is characterised by decreased function of the nephron. It comprises two phases: the acute phase, in which the nephron still fulfils its position and is reversible, and the chronic phase, in which the nephron's ability to filter blood is diminished or null and irreversible.
