Lesson 1 Homeostasis

Question 1

What are the 3 components to homeostasis?

Answer 1

1. Detect the change (notice anything out of the ordinary)
2. Integrations (analyze the problem)
3. Response (brain interprets informations and signals the correct response to deal with the problem)

Question 2

Why does the body need a stable ph and temperature?

Answer 2

Tissue maintenance is necessary so your proteins/enzymes don’t get degraded.

Question 3

What is positive feedback?

Answer 3

Occurs to increase change or output: the result of a reaction is amplified to make it occur more quickly.

Question 4

What is negative feedback?

Answer 4

Occurs to reduce the change or output: the results do the reaction is reduced to being the system back to the stable state. (More common)
