Question

the figure shows a homeostatic system with four components (a, b, c, and
egulated variable\).

which box represents the integrator of the homeostatic system?

a. box a
b. box b
c. box c
d. i do not know the answer.

Explanation:

Identify components of the loop

Using the Homeostasis and Homeostatic Regulation knowledge points:

• The "regulated variable" is detected by a sensor.
• Box A receives input from the regulated variable, making Box A the sensor (receptor).
• Box A sends information to Box B, which processes the signal.
• Box B is the integrator (control center) that compares the input to a set point.

Determine the effector

Using the Homeostatic Regulation knowledge point:

• Box B sends commands to Box C.
• Box C acts as the effector, which directly alters the regulated variable to maintain balance.
• Therefore, Box B represents the integrator.

Answer:

• a. Box A
• b. Box B (Correct answer)
• c. Box C
• d. I do not know the answer.
