Homeostasis, Feedback Loops & Blood Glucose

Homeostasis

• allows for a wildly fluctuating internal environment

• is impossible in vertebrates

• is the maintenance of a relatively stable internal environment and often incorporates a form of feedback regulation

• is the maintenance of a relatively stable external environment and often incorporates a form of feedback regulation

The body system that controls and coordinates all body activities through electric impulse/messages between brain, spinal cord and nerves

• endocrine system

• muscular system

• nervous system

• neuron

Failure to maintain homeostasis could result in

• lack of internal balance

• eventual death

• difficulty carry on metabolism

• all choices

The two types of feedback systems that help organism maintain homeostasis are:

• positive and negative

• static and dynamic

• receptor and effector

• minor and major

Maintaining body temperature is an example of a :

• negative feedback loops

• positive feedback loop

The process of childbirth is an example of:

• negative feedback loop

• positive feedback loop

Human have  $--$  for body temperature, blood glucose concentrations, blood pressure, electrolyte concentrations, and pH levels, etc.  

• postive feedback mechanisms 

• sets points 

• a wide interanl range 

• no regualtion 

The "cause" for something to happen is the:

• response

• effect

• stimulus

• homeostasis

The "effect" of a given stimulus is the:

• response

• stimulus

• cause

• result

What does the term "steady state" refer to with respect to the process of homeostasis?

• balanced external environment

• balanced internal environment

• changing external environment

• changing internal environment
