ANATOMY

Detailed explanation-1: -The kidneys are two bean-shaped organs, each about the size of a fist. They are located just below the rib cage, one on each side of your spine. Healthy kidneys filter about a half cup of blood every minute, removing wastes and extra water to make urine.

Detailed explanation-2: -It consists of water, urea (from amino acid metabolism), inorganic salts, creatinine, ammonia, and pigmented products of blood breakdown, one of which (urochrome) gives urine its typically yellowish colour.

Detailed explanation-3: -The urinary system includes the kidneys, ureters, bladder and urethra. This system filters your blood, removing waste and excess water. This waste becomes urine.

Detailed explanation-4: -The waste that is collected combines with water (which is also filtered out of the kidneys) to make urine (pee). As each kidney makes urine, the urine slides down a long tube called the ureter (say: yu-REE-ter) and collects in the bladder, a storage sac that holds the pee.
