Science Sec 2 Chapter 10 Transport in living things
Needed to carry substances to and from every cell in multicellular organisms
In flowering Plants
Transports water and dissolved mineral salts from the roots to other parts of the plant
Water enter the roots by
Mineral salts enter roots by
Transports food from the leaves to other parts of the plant
How does the Plant transport system work?
The transport system in flowering plants is used to carry
water,minerals and nutrients to all cells of the body.
The transport system is made up of vessels in the
roots,stems and leaves
The xylem and phloem work together to ensure that all cells in the plant get the necessary sugar,water and minerals.
Human Circulatory system
Transports food and oxygen to all parts of the body
Pumps blood around the body
Carry blood around the body
Consists of eateries,veins,capillaries
What is the role of the blood vessels?
Blood circulates through the circulatory system in tubes know as the
Two types of blood vessels are
from the heart
Arteries branch into a network of smaller vessels know as
pass from capillaries to the cells
pass from the cells to the capillaries.
A liquid that carries substances around the body
Consists of plasma,red blood cells and other cells.
The circulatory system also works with other body systems
Food passes from the
into the blood.Oxygen is taken in by the lungs (the main organs in the

cells need a continuous supply of
that needs to be removed
A transport system is needed to transport substances
The main transport system in the human baby is called the
The human transport system consists of three parts:
If one part does not work well,the whole system will be affected
Blood consists of
Red blood cells
Transports oxygen to all cells
White blood cells
Fights against diseases.
These are suspended in a pale yellow liquid called
Transports important substances
prevents blood loss by forming clots
Blood is a mixture of
45% cellular elements
The human heart
The walls of the heart are made up of muscles.
The heart pumps blood around the body.
The human heart is a muscular pump
The septum in the heart separates the 2 ventricles completely
blood in the right side with the oxygenated blood in the left side of the heart.
How blood circulates around our body
Working with other systems in the body.
