Unit 4 Homeostasis Lesson 1 8.0

Question 1

What is feedback in terms of homeostasis?

Answer 1

A cycle of events in which a variable, such as body temperature, blood glucose level, or blood pH, is continually monitored, assessed and adjusted

Question 2

What are three three components of homeostasis feedback?

Answer 2

Sensor
Control Centre
Effector

Question 3

What does the sensor component do?

Answer 3

detects a change in the internal environment and sends a signal to a control center

Question 4

What does the control centre component do?

Answer 4

sets a range of values within which a variable should be maintained, receives information from the sensor, and sends signals to effectors when needed

Question 5

What does the effector component do?

Answer 5

receives signals from a control center and responds, resulting in a change to an internal variable

Question 6

What are three examples of where feedback in homeostasis is used?

Answer 6

Blood Glucose
Temperature
Systolic Blood Pressure
Blood pH
