-forms blood cells |
Muscular system functions | -provides movement
-protection/support
-generated heat and maintains body temperature |
Nervous major organs | -brain and spinal cord
-peripheral nerves
-sense organs |
Nervous functions | -response to stimuli
-coordinates other systems
-interprets sensory information |
Endocrine major organs | -pituitary, thyroid, adrenal gland, pancrease, gonad |
Endocrine function | -adjusts metabolic activity and energy use
-controls changes during development |
Cardiovascular major organs | -heart
-blood
-blood vessels |
Cardiovascular functions | -distributes blood cells, water, nutrients,waste, oxygen and carbon dioxide
-distributes heat |

Urinary functions | -excrete waste products from the blood
-controls water balance by regulations volume of urine
-stores urine
-regulates PH |
Autoregulation | Automatic response in acell, tissue or organ to and environmental change |
Extrinsic regulation | Responses controlled by nervous and endocrine systems |
A homeostasis regulator mechanism consists of? | -receptor (receive stimulus)
-control center (processes and send instructions)
-effector (carries out instructions) |
Set point | Desired value for homeostasis |
Negative feedback | -the response of effector takes care of stimuli
-body normalizes |
Positive feedback | -initial stimulus produces a response that amplifies the original change in conditions
-body is moved away from homeostasis
-normal range NOT retained
-completes a dangerouz process quickly (repairing lacerations) |
Disease | Caused by the failure to maintain homeostasis |
