1. Understanding Various Animal Urinary, Endocrine, and Digestive Structures and Functions

2. 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.

8. 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.

9. 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
