3. Chemical Input & utilities to body
 Life on earth depends on carbon based molecules.
e.g.- Food, petroleum derivative, medicine etc.
 Most of food are carbon based.
e.g.- rice, wheat, milk, corn etc.
 Mechanical operation before edible or input to body.
 Utilities: water, cloth, hygiene etc.

4. Chemical inputs
Carbohy
drate(CH
O mix)
Protein:
N2derive
Fat: fatty
acid,
glycerol
Vitamin:
Retinol,ri
boflavin
Minerals
: Ca, Cl,
K, S etc.

5. Different accessories
PUMPS, FILTER
DIGESTOR, BATCH REACTOR
PH METER

(Alimentary canal)

10. Process Description(Human alimentary canal)
BRAIN COMAND
STOMACH(EXPAND AND
CONTRACTION)
STOMACH GENERATE HCl
ACID, MIX WITH FOOD
ACIDIC FOOD ENTERS
INTENSTINE,INTERACT WITH
LIVER & PANCREASE
LEVER: ACTING ON FAT(AS
EMULSIFYING OF SOAP)
PANCREASE: PROTIEN INTO
AMINO ACID,COMLEX
CARBOHDRATE TO
GLUCOSE,FATS TO GLYCEROL
FOOD ABSORBED BY
INTENSTINE WALL
FOOD TRANSPORT TO EACH
OF CELL & TISSUE
UNABSORBED FOOD ENTER
TO LARGE
INTENSTINE,RECYCLE AND
EXCRETION

Process description
(Human respiratory)

12. Process Description(Human respiratory system)
Air in/out by
nostril,
hair(mucus)
refine the
dust particle,
below like a
one way
valve(pharyn
x)
Diaphragm
promotes
lungs to
expand or
contraction,
acts like
diaphragm
pump
Entered O2
mix with
blood at
heart(also
acts as pump,
transports
blood, waste
material, salt
etc.)
Transport to
each of cell

13. Energy generation process
• Food + O2  Energy + CO2 + H2O ; Exothermic And Aerobic reaction.
• Food + without O2  Energy + Lactic acid[1] ; Anaerobic reaction ***
[1] Cause muscle cramp, its application in moisturizer, cosmetic
industry.
*** Energy generation during more exercise in muscle.

14. Excretion(removal of waste product)
Osmosis: removal of water from selective permeable skin
membrane
Diffusion: CO2, O2by permeable skin membrane. Also CO2 out by
lungs
Filtration: N2waste material(urea, uric acid) remove by
kidney(measures concentration & recycle[e.g. amino acid,glucose])

15. Maintenance of human body
• Need to prevent damage & breakdown
• Occur automatically at every moment of life
• PROCESS + MAINTENANCE = LIFE PROCESS
Control & coordination
 Touching an object, message to brain, brain command to organ.
 hungry, sleep & playing etc. are coordinate by brain

16. Final overview
• Input raw
material(CH
group, acid, O2
etc.)
Different unit
process
• Simplified food
absorb,
transport to
each cell.
O2 reaches to
each cell,
reaction occur • Removal of
waste
product/excret
ion
Recycle of
useful product
