- 3. CONTENTS • Objectives • Introduction • definitions 3
- 4. Objectives • To understand the meaning of basic life process • Definition of various terms used in Basic life process 4
- 5. Basic life Process and Their Function 1.Metabolism 2.Responsiveness 3.Movement 4. Growth 5. Differentiation 6. Reproduction 5
- 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. 6
- 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. . 8
- 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. 9
- 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 10
- 11. Reproduction The formation of new cells for tissue growth, repair or replacement or production of new individual 11
- 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
