Question 36

Homeostatic regulation

Answer 36

The adjustment of physiological systems to preserve homeostasis

Question 37

Autoregulation

Answer 37

A process that occurs when a cell, tissue, organ or organ system responds to some environmental change

Question 38

Extrinsic regulation

Answer 38

A process that results from activities of the nervous system or endocrine system in response to environmental changes

Question 39

Nervous response vs. endocrine response time

Answer 39

``` Nervous = rapid-short term Endocrine = may not be immediate-may last for days/weeks ```

Question 40

What is the primary mechanism for maintaining homeostasis

Answer 40

Negative feedback: provides long term control over the bodies internal conditions and systems

Question 41

In _________, an initial stimulus produces a response that exaggerates or enhances the original change in conditions, rather than opposing it.

Answer 41

Positive feed back

Question 42

When is a positive feedback typically found in the body?
