Response The reaction to a stimulus
Negative Feedback Loop Results in the counteraction (opposite action) of the stimulus
Positive Feedback Loop Results in the increase of the stimulus
Urinary System System that helps maintain homeostasis by removing waste

Homeostasis Condition of balance and equilibrium
Lymphatic System System that helps maintain homeostasis through removal of waste from tissue and aiding immune system
Kidney Major organ of the urinary system responsible for removing liquid waste from the body
Neuron Cell responsible for sending electrochemical signals
Reproductive System System of sex organs within an organism which work together for the purpose of sexual reproduction
