Homeostasis

What is physiology?

The study of the processes in the body

What is homeostasis?

The regulation of internal conditions despite external stimuli

What is a set point?

Optimal range for physiological condition

What is the difference between set point and a normal range?

set point is the exact number and the normal range is the spread of numbers below the set point

What are the 3 parts of a feedback loop?

Sensor, integrating center, effector

What does the sensor do?

detects deviation from the set point

what does the integrating center do?

Determine the necessary response

What does the effector do?

it carries out the physical response

What is negative feedback?

change is counteracted (brought down) to maintain homeostasis

What is positive feedback?

change is amplified to maintain homeostasis
