9. LEARNING OBJECTIVES
1.Describe the transport of substance in xylem
and phloem.
2. Explain the functions of structures in animal
circulation and trace the path of blood in the
systemic and pulmonary circulation; and
3.Differentiate the pulmonary and systemic
circulation.

10. GENERAL INTRODUCTION
• Multicellular organisms possess millions of cells in their body.
• Every cell needs a constant supply of essential substances like
nutrients and oxygen to maintain life and survival.

11. Means of Transort in Plants
Means of Transport in Plants
The transport of materials in and out of the cells is carried out by diffusion
and active transport in plants.

12. GENERAL INTRODUCTION
 Water absorbed by the roots have to reach entire plant and the
food synthesised by the leaves have to be distributed to all the
parts of the plant.
 Water and mineral salts absorbed by the roots reach all parts of
the plant through the xylem.
 The food synthesized by the leaves are translocated to all parts
of the plant through the phloem.
 The bulk movement of substances through the vascular tissue is
called Translocation.

13. Translocation
Is moving food (sucrose and amino acids) from the sources
(leaf, root) to sinks (developing flowers/fruits, storage organs)
through the phloem vessels.

15. • Plants do not have interstitial fluid and circulatory system.
• But they need to move various substances (water, minerals, organic nutrients,
growth regulators etc.) over long distances.
TRANSPORT IN PLANTS
8

16.  Unidirectional transport:
E.g. Transport of water and minerals in
xylem (from roots to stems, leaves etc.).
 Multidirectional transport:
E.g. Transport of photosynthesis (organic
compounds), transport of mineral
nutrients etc. in phloem.
TRANSPORT IN PLANTS Direction of transport
Sometimes, plant hormones and other
chemical stimuli are transported in a
polarized or unidirectional manner from
where they are synthesized to other parts.

Means of Transport in Animals

19. GENERAL INTRODUCTION
‘Transport’ means to carry things from one place to
another.
In larger organisms transport of nutrients, salts,
oxygen, hormones and waste products around the
body are performed by the ‘Circulatory system’.
The circulatory system consists of the flowing
circulating fluids;
blood
lymph
heart
blood vessels

20. Diffusion
The movement of solid liquid and gaseous molecules
from a region of higher concentration to
a region of their lower concentration
without the utilization of energy is called Diffusion.
This is a passive process.

21. 07/23/2021
Animals have 2 types of transport
systems:
-Open Circulatory Systems
-Closed Circulatory Systems (Single Circulation
Systems and Double Circulation System)

22. 07/23/2021
The delivery system of
the heart is separated
into two circuits:
• Pulmonary Circuit
• Systemic Circuits

23. The responsible for the
transport of blood
throughout the body.
three types of blood
vessels:
• Arteries
• Veins
• capillaries

Blood Vassals

24. A special connective tissue
that distributes essential
nutrients, including
• oxygen while collecting
wastes
• carbon dioxide.

Blood

25. Right side pathway:
1.Deoxidized blood from the
whole body enters the right
atrium through two large veins,
the inferior vena cava, and the
superior vena cava.
2.The tricuspid valve opens,
allowing blood to flow from the
right atrium to the right ventricle.
3.When the right ventricle is full,
the right ventricle is compressed,
the tricuspid valve closes, and the
pulmonary valve opens.
4. Blood flows through the pulmonary arteries to the lungs where it is oxygenated
Pathway of Circulation System

26. Left side pathway:
1. Oxygen-rich blood travels
from the lungs to the left atrium
through large veins called the
pulmonary veins.
2. The mitral valve opens and
blood is pumped from the left
atrium to the left ventricle.
3. When the left ventricle is
full, the left ventricle is
compressed, the mitral valve
closes, and the aortic valve
opens.
4. The heart pumps blood
through your aortic valve to your
aorta, where it flows to the rest
of the body.
