Hemeostasis

Question 1

Homeostasis

Answer 1

Homeostasis is the body’s way of keeping internal conditions stable and balanced, even when the outside environment changes.

It means your body wants to stay consistent, like keeping the same temperature, pH level, or blood sugar.
The body only allows slight changes, and uses feedback systems (like negative feedback) to bring things back to normal.

Question 2

Negative Feedback

Answer 2

Purpose: To bring the body back to normal (the set point).
How it works: When something in the body changes too much (like temperature, blood sugar, etc.), the body does the opposite to fix it.
Example:
If your body gets too hot, you sweat to cool down.
If blood sugar is too high, insulin lowers it.
🡒 Think: “Reverse the change.”

Question 3

Positive Feedback

Answer 3

Purpose: To amplify or continue a process until it’s done.
How it works: The body responds by increasing the change instead of reversing it.
Example:
During childbirth, contractions trigger hormones that cause stronger contractions until the baby is born.
When you get a cut, the body keeps making platelets to form a clot until it’s sealed.
🡒 Think: “Keep it going.”

Question 4

Receptor

Answer 4

It responds to changes called stimuli by sending information input to the seccond component.Through affrent pathway

Question 5

Control centre

Answer 5

Analyzes the information it remand then determines the appropriate response or course of action.

Question 6

Effector

Answer 6

An effector is a muscle, gland, or organ that carries out the response sent by the control center to help the body return to or continue maintaining homeostasis.
