| Question | Answer |
|---|---|
| Refers to the body's ability to set a maintenance mechanism of relatively constant internal conditions despite changes in either internal or external environment. | Homeostasis |
| The body's normal reading or range of normal | set point or setpoint range |
| The body's ability to self-regulate or return to normal | homeostasis |
| This body system separates internal environment from external environment, providing stability of internal fluid volume | Integumentary |
| Body system that supports and protects internal environment, allowing movement; stores minerals that can be moved into and out of internal fluid | Skeletal |
| System that powers and directs movement; provides heat | Muscular |
| System that regulates homeostatic mechanisms, sensing changes, integrating information, sending signals to effectors | Nervous system |
| Regulates homeostasis by secreting signaling hormones that travel through internal environment to effector cells | Endocrine |
| System that maintains internal constancy by transporting nutrients, water, oxygen, hormones, wastes, and other materials and heat within the internal environment | Cardiovascular |
| system that maintains constant fluid pressure by draining excess fluid from tissues, cleaning it, and recycling it to bloodstream | Lymphatic |
| Bodily system that defends internal environment against harmful agents | Immune |
| Bodily system responsible for the stable maintenance of oxygen and carbon levels in the body by exchanging these gases between external and internal environments; provides vocal communication with others for protection, hunting, etc. | Respiratory |
| maintains relatively constant nutrient levels in the body by digesting food and absorbing nutrients into internal environment | Digestive |
| Maintains constantly low level of waste and regulates pH of internal environment; helps maintain constancy of internal water volume and balance of ions and other substances | Urinary |
| Passes genetic code containing information for forming a body and maintaining homeostasis to offspring | Reproductive |
