Homeostasis:

Question 1

Homeostasis:

Answer 1

The body’s ability to maintain stable internal conditions despite changes in the external environment.It is a dynamic balance where internal conditions fluctuate within narrow limits to ensure proper functioning.

Importance:
Homeostasis is crucial for survival, as it ensures proper functioning of the body by regulating factors like temperature, nutrient levels, and waste. Nervous and endocrine systems communicate to keep everything balanced and working smoothly.

Question 2

Negative Feedback:

Answer 2

This is when the body detects a change and works to reverse it, bringing things back to normal. For example, when your body gets too hot, it starts sweating to cool down and bring your temperature back to a safe level.

Question 3

Positive Feedback:

Answer 3

: This is when a process is amplified or increased until a specific outcome is achieved. For example, during childbirth, the body releases oxytocin, which increases the intensity of contractions, causing more oxytocin to be released until the baby is born.

Question 4

13. Identify and describe the components of a
    homeostatic mechanism, and explain how
    they interact to maintain homeostasis

Answer 4

The receptor detects a change (e.g., rise in body temperature).
It sends this information to the control center (e.g., hypothalamus in the brain).
The control center compares the change to the body’s set point and sends a signal to the effector (e.g., sweat glands).
The effector initiates the response (e.g., sweating) to counteract the change.
Once the body returns to normal (e.g., temperature decreases), feedback signals stop the response, completing the cycle.
