Regulation of Water Balance

Provides the means for the control center’s response (output) to the stimulus.

Most homeostatic control mechanism are ________ feedback mechanism.

As we age our organs becomes _____ efficient. Internal condition becomes _______ stable.

the same

fight and flight responses are evolutionary adaptations to _______ the chances of survival.

blood glucose regulation

hormone regulation

Homeostasis indicates a dynamic state of equilibrium or balance.

is a mechanism that reverse a deviation from the set point.

unchanging

blood pressure regulation

Determines the appropriate response or course of action.

Hormonal imbalance will place us at an increasing risk for illness and produces the changes we associate with ________.

It will reduce the amount of change (negative feedback).

Fever response

It is the body’s ability to maintain relatively stable internal conditions even the outside environment or world is constantly changing.

______ or inappropriate activation of the fight or flight response is implicated in a range of clinical conditions including most anxiety disorders

It determines the level or set point at which a variable is to be maintained.

It is a type of sensor that monitors and responds to changes in the environment.

The perception of ________ – activate the sympathetic nervous system – acute stress response – prepares the body for “fight or flight.

Homeostasis indicates a dynamic state of equilibrium or unstableness.

In homeostasis, internal conditions change but managed to adjust within normal limits.

sweating

The effect of the response to stimulus: shut off the original stimulus or _______ its intensity.

The information flows from the ________ – control center – afferent pathway.

It is very sensitive to change

It will increase the amount of change (positive feedback)

Information flows from the control center – _________ – efferent pathway.

body temperature regulation

blood clotting is an example of

It analyzes information it receives

are rare because they tend to increase the original stimulus.

All homeostatic control mechanism have at least three components:

Homeostasis is important because most disease can be regarded as a result of its disturbance.

Oxygen and Carbon Dioxide Levels in Breathing

It is the automatic physiologic reaction to an event that is perceived as stressful or frightening.

childbirth is an example of

These are responsible in maintaining equilibrium by doing their respective functions.
