This document defines and describes the basic life processes in living organisms. It outlines six key processes: metabolism, responsiveness, movement, growth, differentiation, and reproduction. Metabolism is defined as the sum of all chemical reactions in the body, including catabolism that breaks down molecules and anabolism that builds them up. Responsiveness is the ability of the body to detect and respond to internal and external changes through nerve and muscle cell responses. Movement refers to the motion of the whole body enabled by coordinated muscle contraction. Growth is defined as an increase in body size through increased cell size or quantity. Differentiation is the development of cells from unspecialized to specialized states. Reproduction enables the formation of new cells needed for

6. Metabolism
It is the sum of all the chemical process that occur
in the body
(a) Catabolism :- breakdown of complex chemical
substances into simpler components
(b) Anabolism :- the building up complex substance
from smaller, simpler components
E.g:- digestive processes catabolize protein in food
into amino acid. These amino acid then used to
anabolism (build) new proteins that make up body
structure such as muscle and bone.

7. Responsiveness
The body ability to detect and respond to changes.
Example
1. increase in the body temperature represent a
change in internal environment
2. turning head toward the sound is a response of
external environment.
Nerve cells response by generating electrical signals
known as nerve impulse
Muscle cells response by contracting which generate
force to move body parts. 7

8. Movement
It means motion of the whole body.
Example
1. Coordination action of legs.
2. When body tissue damage WBC move from
blood into affected tissue to help repair area.

9. Growth
• Increase in body size that result from an increase
in the size of existing cells, tissue some time
increase in size because the amount of material
between the cells increase.

10. Differentiation
The development of cell from an unspecialized
to specialized state.
Example
A fertilized egg (ovum) develops into an embryo,
then into foetus, an infants, child, finally adult

11. Reproduction
The formation of new cells for tissue growth,
repair or replacement or production of new
individual

12. Body Fluid
12
• Intera cellular fluid (ICF) :- the watery solution
containing dissolved chemical that are found
inside cells as well as surrounding them.
• Extra Cellular fluid (ECF):- the fluid outside the
body cells.
• Interstitial fluid :- ECF that fill the narrow
space between cell of tissue

13. Body Fluid
13
• ECF with blood vessel is called blood plasma
• ECF with in lymphatic vessel is called Lymph
• ECF around the brain and spinal cord is called
Cerebro spinal fluid (CSF)
• ECF in joint is Synovial Fluid
• ECF in eye is called Aqueous Humor or
Vitreous body
