relatively constant state maintained by the body

Examples of Homeostasis

1. Temperature Regulation 2. Regulation of blood carbon dioxide level 3. Regulation of blood glucose level

Afferent - goes toward a control center Efferent - goes away from the control center

Intracellular control

1. Regulation within cells 2. genes or enzymes can regulate cell processes

Intrinsic control (autoregulation)

1. Regulation within tissues or organs 2. May involve chemical signals 3. May involve other "built in" mechanisms

1. Regulation from organ to organ 2. May involve nerve signals 3. May involve endocrine signals (hormones)

contain the same number or protons but different numbers of neurons

atoms with fewer or more than 8 electrons in the outer energy level will attempt to lose, gain, or share electrons with other atoms to achieve stability

Facilitated diffusion

transports substances down a concentration gradient

Active transport processes

require the expenditure of metabolic energy by the cell

process by which large molecules can leave the cell even though the are too large to pass through the plasma membrane

Question	Answer
Homeostasis	relatively constant state maintained by the body
Examples of Homeostasis	1. Temperature Regulation 2. Regulation of blood carbon dioxide level 3. Regulation of blood glucose level
Feedback Loops	Afferent - goes toward a control center Efferent - goes away from the control center
Intracellular control	1. Regulation within cells 2. genes or enzymes can regulate cell processes
Intrinsic control (autoregulation)	1. Regulation within tissues or organs 2. May involve chemical signals 3. May involve other "built in" mechanisms
Extrinsic control	1. Regulation from organ to organ 2. May involve nerve signals 3. May involve endocrine signals (hormones)
Isotopes	contain the same number or protons but different numbers of neurons
Octet rule	atoms with fewer or more than 8 electrons in the outer energy level will attempt to lose, gain, or share electrons with other atoms to achieve stability
