Answer:
Aging is a biological phenomenon which adversely affect urinary system. When a person reach to the age of 30-40, about two third of people have kidney problems because of their abnormal function. Fun fact! the supply of blood to glomerulus decreases which slow down the filtration process. The blood vessels thickens so the supply of blood to kidney decreases. Prostrate gland enlarge with aging which block the urinary pipe and may lead to kidney damages. The urinary sphincter becomes loose so urine can not be hold in urinary bladder,
