Flashcards in Homeostasis And Metabolism Deck (13):
1

homeostasis

overall steady state within the organism

2

extracellular fluid

includes all body fluids outside the cells (blood plasma, lymph, fluid between cells in tissue)

3

intracellular fluid

contained inside the cells

4

negative feedback

method for maintaining homeostasis, a controlled system based on information returning to a source.

5

negative feedback loop

sensor, control center, effector

6

sensor

gathers information about a given body condition

7

control center

compares the sensor inputs with the set point and sends a corrective signal if necessary

8

effector

responds to the signal

9

insulin

a hormone produced by the pancreas that acts as a signal traveling through the bloodstream to effector cells

10

metabolism

made up of life-sustaining reactions that occur within the body systems

11

catabolism

a type of activity of metabolism where complex substances are broken down into simpler compounds

12

adenosine triphosphate (ATP)

energy obtained by catabolism nutrients used to form a compound called "Energy currency"

13

anabolism

type of activity in metabolism where simple compounds are used to manufacture materials needed for growth, function, and tissue repair
