Homeostasis refers to the process by which the human body regulates its internal conditions such as temperature and pH levels. It is essential for the body to maintain homeostasis in order to function properly. The body uses negative and positive feedback loops to control various systems and return conditions to normal set points when deviations occur. Examples of homeostasis in the body include temperature regulation, blood glucose levels, water balance, and calcium levels.

1. HOMEOSTASIS
By: Zharfa

2. WHAT IS
HOMEOSTASIS?
Homeostasis is a system that
regulates the human body so
that it can maintain a constant
condition such as temperature
or pH

3. “
Why Do We Need
Homeostasis?
Homeostasis is very much needed for
the human body to function well.
Without homeostasis our body won’t
be able to maintain a well internal
system.

4. Examples of
Homeostasis
on Our Body
⊙ Temperature
⊙Water level
⊙ Blood glucose regulation
⊙Calcium balance
⊙ Everything else that require
internal control

5. HOW DOES IT
WORK?

6. Homeostasis has
feedback regulations
which control the
body.
In homeostasis there
are two types of
feedback: negative
and positive

7. Negative
Feedback
A negative feedback control system responds when
conditions change from the ideal or set point and
returns conditions to this set point.

8. Positive
Feedback
Positive feedback does not maintain homeostasis.
Instead, it increases responses and processes
moving it further and further away from the
system.

Regulation
Blood Vessels : The contraction
and dilation of the arterioles
regulate the body temperature
called vasodilation

Sweat Glands
Sensory Receptors
