92
Q

homeostatic three components:

A

receptor
center of control
effector

93
Q

A

receptor

94
Q

will process and integrate what is happening

A

center of control

95
Q

produce a response appropriate to the change.

A

effector

96
Q

are two main types of feedback to which the system reacts:

A

97
Q

a reaction in which the system responds in such a way as to reverse the
direction of change.

A

Negative feedback

98
Q

a. Thermoregulation
b. Carbon dioxide concentration
c. Blood sugar level

what feedback?

A

Negative feedback

99
Q

a response occurs to amplify the change in the variable.

100
Q

is less common in
naturally occurring systems than negative feedback, but it has its applications.

A
