What is the receptors function

Monitors controlled condition
What is Control Center function

Receives input and provides output
What is Effectors function

Bring about change in controlled condition
What are Baroreceptors

They are in the walls of blood vessels. They sense blood pressure.
Why are Negative feedback loops most common of the homeostatic circuit

Because they are self-controlling: they cannot spin out of control if they are over-stimulated
If a response enhances or intensifies the stimulus, what system is operating

Positive feedback loop
Oxytocin

a hormone that travels through the bloodstream to increase contractions in the uterus
Positive feedback Examples
- Blood Clotting
- Childbirth
- Sever blood loss
- Child stops suckling or milk is depleted
Negative feedback Examples
- Body temperature
- Blood Glucose
- Many, many others
Positive feedback loop Characteristics
- Strengthen or reinforce a change
- Action continues until it is interrupted
- Reinforces conditions that do not happen very often
Negative feedback loop Characteristics

Reverses a change in a controlled condition

Action stops automatically when setpoint is reached

Regulate conditions that remain fairly stable over long periods.
Hypertension is also known as

High blood pressure
If the setpoint for fats is abnormal we call this

dyslipidemia
If the homeostatic loop for the pancreatic hormone insulin (receptors and control center), or the cells that respond to it (effector), is abnormal, which causes blood sugar levels to be abnormal, this disease is called

Diabetes mellitus (there are two types, called "type I" and "type II"
