Activity Sheet 1
The Circulatory System – Dictagloss
All animals need to transport materials around to the different parts of their
body. This is the job of the circulatory system. The circulatory system consists
of a liquid called blood, a pump called the heart and a series of vessels called
veins and arteries. One thing that must be transported around is a gas called
oxygen. Oxygen enters the blood through the lungs. It is then pumped through
the heart and around the body where it is used along with food to make energy.
The body produces another gas called carbon dioxide which is a waste product.
This gas is carried back to the heart and then to the lungs where it is released
back into the atmosphere. The vessels that transport blood away from the
heart are called arteries. The blood in arteries is bright red because it is rich
in oxygen. The vessels that transport blood to the heart are called veins. The
blood in veins is dark red because it is low in oxygen. Capillaries are small
vessels that join the arteries and veins. Nutrients from food are also
transported around the body by the circulatory system. They enter the blood
from the small intestine. The circulatory system also helps to regulate
temperature by transporting heat around the body.

of a liquid called blood, a pump called the heart and a series of vessels called

One thing that must be transported around is a gas called oxygen. Oxygen
enters the blood through the lungs. It is then pumped through the heart and

The Circulatory System – Investigating Technical Language
The circulatory system is made up of the vessels and the muscles that help and
control the flow of the blood around the body. This process is called circulation.
The main parts of the system are the heart, arteries, capillaries and veins.
The centre of the circulatory system is the heart, which is the main pumping
mechanism. The heart is made of muscle. The heart is hollow so that it can fill
up with blood. The heart is positioned behind the ribcage and between the
lungs. It is the pump that keeps this transport system moving. The blood is the
transport system by which oxygen and nutrients reach the body's cells, and
waste materials are carried away.
First, oxygen is inhaled into the lungs and passes through the capillary walls
into the bloodstream. The blood is a brighter red as it is rich in oxygen that we
have inhaled from the lungs.
Then the veins carry the blood to the left side of the heart. It enters the left
ventricle which is the lower chamber of the heart before being pumped through
to the upper chamber called the left atrium.
Next, the left side of the heart pumps the blood through the largest artery
called the aorta and through to rest of the body. Then the oxygen is released
to the cells. This is important for the cells in the brain and the body to do their
work. The oxygenated blood travels throughout the body in its system of
arteries into the smallest arterioles.
The tubes that carry blood away from your heart are called arteries. They're
hoses that carry blood pumped under high pressure to smaller and smaller
branched tubes called capillaries. The tubes that more gently drain back to the
heart are veins.
On its way back to the heart, the blood travels through a system of veins.
Carbon dioxide (a waste product) is picked up by the blood. It is taken by two
large veins to the right side of the heart. Blood enters the vena cava and goes
into the right atrium down to the right ventricle.
Then the right side of the heart pumps the blood through the arteries to the
lungs. As it reaches the lungs, the Carbon dioxide exits the blood through the
capillary walls. The lungs expel the carbon dioxide. It is then replaced with
fresh oxygen that we have inhaled through the lungs. Then the process begins
all over again.

the centre of the circulatory system is the heart, which is the main pumping

The blood is the transport system by which oxygen and nutrients reach the

As blood begins to circulate, it leaves the heart by the left ventricle and goes
into the aorta. The aorta is the largest artery in the body. The blood leaving
the aorta is full of oxygen that we have inhaled from the lungs. This is
important for the cells in the brain and the body to do their work. the

and replaced with fresh oxygen that we have inhaled through the lungs. Then
the process began all over again.

The Circulatory System – Reconstructing text
Oxygen is inhaled into the lungs and passes through the capillary walls into the
bloodstream
Veins carry the blood into the left side of the heart. It enters the left ventricle and is
pumped into the left atrium.
The blood then enters through the largest artery called the aorta and through to the rest
of the body.
Arteries carry the blood away from the heart and oxygen is released into the cells
through finer tubes called capillaries.
The blood now travels back to the heart through a system of veins. It has picked up a
waste product called Carbon dioxide.
The blood enters the vena cava and is pumped into the right atrium and then the right
ventricle.
Then the right side of the heart pumps the blood through the arteries to the lungs.
As it reaches the lungs, Carbon dioxide is expelled through the capillary walls. The lungs
expel the carbon dioxide and replace it with fresh oxygen.
