(1)The urinary system's function is to filter blood and create urine as a waste by-product.

(2) two kidneys we have.

(3)The kidneys act as very efficient filters for ridding the body of waste and toxic substances, and returning vitamins, amino acids, glucose, hormones and other vital substances.

(4)Two ureters. These narrow tubes carry urine from the kidneys to the bladder. Muscles in the ureter walls continually tighten and relax forcing urine downward, away from the kidneys.

(5)A hollow, muscular, balloon-shaped organ that expands as it fills with urine.

(6)The urethra is the vessel responsible for transporting urine from the bladder to an external opening in the perineum.

(7)Urine is formed in the kidneys through a filtration of blood. The urine is then passed through the ureters to the bladder, where it is stored. During urination, the urine is passed from the bladder through the urethra to the outside of the body.
