  2. Learning Target I can identify the structures and functions of the urinary system.

  3. The urinary system’s chief responsibility is the excretion or removal of wastes. • It removes wastes from the body through the filtration of blood.

  4. The urinary system consists of two kidneys, two ureters, a bladder, and a urethra.

  5. Kidneys • The kidneys filter and remove waste products and some water from blood. • In addition, the kidneys sustain water and electrolyte, or mineral, balance in order to maintain homeostasis.

  6. Ureters • The ureters are thick-walled muscular tubes that connect the kidneys to the urinary bladder.

  7. Bladder • The urinary bladder is an elastic and expandable muscular organ that stores urine, which is produced in the kidneys. • After a certain amount of urine has collected, nerve endings will stimulate the contraction of the bladder and urine will pass out of the bladder to the urethra.

  8. Urethra • The urethra transports urine from to the urinary bladder to outside of the body. • In both males and females it serves as the passageway for the removal of urine
