TRANSPORTATION IN ANIMALS AND PLANTS

1. Transportation in Animals and
Plants

3. Living things both plants and
animals including man need a
transport system

4. TRANSPORT SYSTEM IN ANIMALS
4
We need TRANSPORT when
• 2 cells are far away from each other
• materials needed to be moved from
one place to another place.

5. TRANSPORTATION IN
ANIMALS
5
➢ All organisms need food, water and oxygen for
survival
➢So they need to transport all these.
➢Wastes also to be transported.
➢The system carrying on this function is called
circulatory system.
It consists of blood, blood vessels and Heart.

transport system in our body.

8. Your Blood is made of
8
• Plasma
– Liquid part of blood
• Red Blood Cells
– They carry oxygen
to all parts of the
body

9. • White Blood
Cells
–Fight and kill
germs that
may enter your
bloodstream

10. • Platelets
–Form “scabs”
when you cut
yourself
–Helps stop the
bleeding

11. BLOOD
11
■ Blood is the fluid which flows in the blood vessels. The
fluid part of blood is called Plasma which contain cells of
various kinds suspended in it.
■ It transports substances like digested food from the
intestine to the other parts.
■ It carries oxygen from the lungs to the cells if the body.
■ Transports wastes for removal from the body.
■ (1)RBC:- contain red pigment called haemoglobin.
■ Haemoglobin binds with oxygen and transports to all
body parts.
■ (2) White blood cells:- fight against germs that may enter
our body.
■ (3) Platelets:- help in blood clotting.

Q. What’s the use of valve?

16. Valves promote One-way flow of
blood.
When Valve is opened
blood can flow
When Valve is closed
blood can’t
flow back

18. BLOOD VESSESLS
■ Two types of blood vessels. Arteries and veins.
■ Arteries carry oxygen rich blood from heart to all parts of
body.
■ Veins carry co2 rich blood from all parts of the body back
to heart.
■ Capillaries:- extremely thin tubes join up to form veins.
Differences between arteries and veins
1. Carry oxygen rich blood
from heart to body parts
2. Have thick elastic walls.
3. Blood pressure is high
and flow is rapid
4. No valves
1.Carry co2 rich blood from
All parts of body back to heart.
18
2. Have thin walls
3. Blood pressure is low.
4. Valves present.

19. Heart
19
● it acts as a pump for transport of blood.
● It is located in the chest cavity with its lower tip slightly
tilted towards the left.
● Heart has 4 chambers- the two uppper chambers
called ventricles and two lower chambers called
ventricles.
● Heartbeat:- the rhythmical contraction abd relaxation
constitute heart beat. Stethoscope is used to feel the
heart beat.
● Each heart beat generates one pulse in the arteries.
● Pulse rate per minute indicates the rate of heart.
● Animals such as sponges and Hydra do not possess any
circulatory system. Exchange of materials takes place
through water in which they live.

20. Excretory system
20
● The process of removal of wastes
produced in the living cells is called
excretion.
● Excretory system in humans contain
● 1.pair of kidneys
● 2.ureters
● 3.Urinary bladder
● 4.urethra.

23. Excretory mechanism
23
● When blood reaches to the kidneys the
nephrons present in the kidneys filter the
blood . The useful substances are
absorbed back into the blood and the
wastes dissolved in water are removed as
urine. From the kidneys the urine goes
into the urinary bladder through ureters.it
is stored in the bladder and is passed out
through urethra.

26. EXCRETION IN
ANIMKALS
■
26
■
An adult human being normally pases about 1-1.8L of urine
in 24 hrs.
Urine consists 95% water, 2.5% urea and 2.5 % other waste
products.

27. TRANSPORT OF SUBSTANCES IN PLANTS
■ Transport of water and minerals:-
Plants absorb water and minerals by roots through root
hairs
Plants have pipe like vessels to transport water and
nutrients.
27
➢
➢ .

28. A tissue is group of cells that perform
specialized function in an organism.
➢ Xylem for transport of water and
nutrients while phloem for transport of
food.
➢ Xylem and phloem together form
vascular tissue

31. TRANSPIRATION
31
■ the evaporation of water through the stomata present on
the surface of leaves is called transpiration.
■ Transpiration generates a suction pull which can pull
water to great heights in the tall trees.
■ It causes cooling effect in plant.

32. AVOID PLASTICS AS FOR AS POSSIBLE

■ As a responsible citizen remember the 4R
principle
■ Reduce
■ Reuse
■ Recycle
■ Recover
