Homeostasis

Name two types of feedback loops.

• Negative and Inhibitor

• Positive and Negative

• Stimulator and Increaser

• Thermostat and Regulator

What are the 3 necessary components of a homeostatic feedback loop?

• Receptor, regulator, thermostat

• receptor, control center, regulator

• Stimulator, control center, receiver

• Receptor, control center, effector

A sensor that monitors and responds to changes in the environmental is called the _________________________.

• control center

• receptor

• effector

• receiver

Determines the level or set point at which a variable is to be maintained. Analyzes the information received by the receptor.

• Control Center

• Receptor

• Effector

• Receiver

Provides a way for the response to get back to the stimulus and either stop it or enhance it.

• Control Center

• receptor

• effector

• receiver

Most of the homeostatic feedback mechanisms are positive feedback systems.

• True

• False

Positive Feedback loops ___________________.

• Reverse or stop the response

• Enhance or increase the stimulus

• Continues to increase until the stimulus is stopped

• Both B & C

Negative Feedback loops _______________.

• Are not common in the human body

• Help with blood glucose regulation

• Are like a thermostat in a house

• Both B & C

An example of a positive feedback loop is ____________.

• Childbirth

• Blood Pressure regulation

• Thermoregulation

• All of the above

An example of a negative feedback loop is

• Blood glucose regulation

• Blood pressure regulation

• Thermoregulation

• All of the above
