How is oxygen used by your body cells? | release energy during cellular respiration |
The liquid waste removed from the body by the urinary system is called | urine |
What purpose do the kidneys serve in the urinary system? | They filter liquid wastes from blood. |

The organ that helps maintain homeostasis by controlling the amount of water in your urine is called the | kidney |
What are four ways the body disposes of waste products? | Through the urinary system (eliminates liquid waste), respiratory system (removes water vapor and waste gases), digestive system (removes solid waste from food), and skin (releases waste through sweat glands). |
Which system removes liquid waste from the blood | urinary system |
Which system removes water vapor and waste gases | respiratory system |
Which system removes solid waste | digestive system |
These glands move waste water | sweat glands |
The looping tubes inside the kidneys that regulate the composition of blood are | nephrons |
The ability to do work or to cause a change | energy |
Muscle that performs involuntary movement and is found inside certain organs, such as the stomach | smooth muscle |
The process by which an organism or cell maintains the internal conditions needed for health and functioning, regardless of outside conditions | homeostasis |
A process in which cells use oxygen to release energy stored in sugars (glucose) | cellular respiration |
A system that interacts with the environment and with other body systems to bring oxygen to the body and remove carbon dioxide | Respiratory system |
A substance that an organism needs to live. | nutrient |
The process of breaking down food into usable materials | digestion |
The system that work together to transform the energy and materials in food into forms the body can use | digestive system |
Wavelike contractions of smooth muscles in the organs of the digestive tract | peristalsis |
A group of organs that filter waste from an organism’s blood and excrete it in a liquid called urine | urinary system |
Liquid waste that is secreted by the kidneys | urine |
