Integumentary (system function)

Separates internal environment from external environment, providing stability of internal fluid volume

Skeletal (system function)

Supports and protects internal environment, allowing movement; stores minerals that can be moved into and out of internal fluid

Muscular (system function)

Powers and directs movements, provides heat

Nervous (system function)

Regulates homeostatic mechanisms, sensing changes integrating information, sending signals to effectors

Endocrine (system function)

Regulates homeostasis by secreting signaling hormones that travel through internal environment to effector cells

Maintains internal consistency by transporting nutrients, water, oxygen, hormones, wastes, and other materials and heat within the internal environment

Maintains constant fluid pressure by draining excess fluid from tissues, cleaning it and recycling it to bloodstream

Defends internal environment against harmful agents

Maintains stable O2 (oxygen) CO2 (carbon dioxide) levels in body by exchanging these gases between external and internal environments; provides vocal communication with others for protection, hunting, etc.

Maintains relatively constant nutrient level in body by digesting food and absorbing nutrients into internal environment

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.

Passes genetic code containing information for forming a body and maintaining homeostasis to offspring

Identifying the characteristic or condition being controlled.

Control center of the feedback loop.

Organs, like muscles or glands, that directly influence controlled physiological variables.

Part of the brain where feedback info relayed through the nerves to the "thermostat"

A hormone secreted by pituitary gland when triggered like increased stretch feeding back to the brain. ((a hormone and neuropeptide that plays a crucial role in various physiological and psychological processes))

What term describes a signal traveling toward a particular center or point of reference?

Signal conducted or conducting outward or away from something (for nerves, the central nervous system; for blood vessels, the organ supplied).
