In this presentation we have discussed the basic life process of the humans.

2. CONTENTS
• Objectives
• Introduction
• Basic Life Process and their functions

3. Objectives
•To understand the meaning of basic life process
•Definition of various terms used in Basic life
process

4. Basic life Process and Their Function
1.Metabolism
2.Responsiveness
3. Movement
4. Growth
5. Differentiation
6. Reproduction

5. 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 anabolise
(build) new proteins that make up body structure such
as muscle and bone.

6. Responsiveness
The body’s 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. 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.
.

8. 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.

9. 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

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

11. Body Fluid
• 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

12. Body Fluid
• 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
