Feedback Flashcards
Homeostasis
All the things living organisms do that cause it to maintain a relatively constant, stable, internal environment regardless of the external environment
5 things all living things do and have
Made up of cells, grow and maintain structure by taking in chemicals and energy from their environment, respond to the external environment, reproduce and pass on their organization to their offspring, at the species level evolve/change and adapt to the environment
Negative feedback
Stimulus - receptor - regulator Center (hypothalamus) - adaptive response - normalcy - cancellation
Positive feedback
Same as negative though does not bring about an adaptive response that cancels the stimulus.
Instead, it causes the stimulus to be increased (or amplified)
This causes a greater adaptive response, which in turn causes a greater stimulus, and so on.
Helps drive processes to completion.
