Lesson 1- Homeostatic Control Systems

Question 1

why is the process of homeostasis often referred to as a dynamic equilibrium?

Answer 1

homeostasis maintains a stable internal environment, it uses systems to take in the nutrients, sense, respond to changes, synthesize macromolecules, protect body, and reproduce. all of these functions and structures make this dynamic and the ability to balance or rest makes it an equilibrium

Question 2

sensor

Answer 2

detects when homeostasis has been disturbed and sends a message to the integrator

Question 3

integrator

Answer 3

relays information to appropriate regulator/effector

Question 4

effector

Answer 4

acts to restore normal balance

Question 5

negative feedback

Answer 5

when body goes out of normal range, body will take action to return to its optimal range (hot or cold temp)

Question 6

positive feedback

Answer 6

move variable furter away from steady rate, not useful for maintaining homeostasis (cut skin attracts platelets to clot blood)
