Term
|
Definition
| consists of the hormonal glands, which secrete chemicals that serve as messengers between body parts. along with the nervous system, it helps maintain a relatively constant internal environment by coordinating and regulating the functions of the body's other systems. it acts slower than the nervous system does, but has a more sustained effect |

|
|
Term
|
Definition
| a stable internal environment |
|
|
Term
|
Definition
| the primary homeostatic mechanism that keeps a variable close to a particular value or set point, the sensor detects a change in environment, the control center activates the effector, the effector reverses the initial change and brings conditions back to normal again |
|
|
Term
|
Definition
| a sensor will trigger the control center which in turn activate the effector, however the effector in this type of feedback mechanism produces a response that continues to stimulate the sensor |

Term
|
Definition
| secretion of hormones for chemical regulation of all body systems |
|
|
Term
| blood and cardiovascular system |
|
Definition
| transportation and defense, red blood cells and blood plasma (the liquid fraction of blood) transport oxygen, carbon dioxide, nutrients, and wastes. platelets in blood participate in the clotting process, preventing excess blood loss. white blood cells defend against infection. the cardiovascular system conducts blood to and away from capillaries, where exchange occurs. the heart pumps the blood and thereby keeps it moving toward the capillaries |
