Homeostasis

Question 1

Homeostasis

Answer 1

The tendency of an organism to maintain a stable Internal environment.

Question 2

Set Point

Answer 2

The physiological value (condition) around which the normal range fluctuates. (ex. blood pressure, temperature, levels of certain nutrients.)

The set point for normal human body temperature is 37 degrees Celsius (98.6 degrees Fahrenheit).

Question 3

Normal range

Answer 3

The restricted set of values that is optimistically healthful and stable.

Body Temperature and blood pressure tend to fluctuate within a normal range a few degrees above and below the set point of 37 degrees Celsius(98.6 degrees Fahrenheit).

Question 4

Negative Feedback

Answer 4

The maintenance of homeostasis that reverses a deviation from the set point(internal body temperature(homeostasis) which is 37 degrees Celsius (98.6 degrees Fahrenheit.

Question 5

3 basis components of Negative Feedback

Answer 5

1)Sensor(aka receptor)- monitors a physiological value (like blood pressure, body temp., etc.). That value is reported to the control center.

2)Control Center-Compares the value to the normal range. If the value deviates too much from the set point, then the control center activates an effector.

3) Effector- causes a change to reverse the situation and return the value to a normal range.
