Slide 1

The Circulatory
System

OB14, OB15
 Understand the structure and function of the
heart, identify the four chambers of the
heart, and explain the difference between
the left and right ventricles
 Describe the passage of blood through the
heart and lungs via arteries and veins,
identify the pulmonary artery and vein, aorta
and vena cava, and distinguish between
arteries, veins and capillaries

There are THREE types of blood
vessels
ARTERIES
 Carry blood away
from the heart
 Thick, muscular,
stretchy wall
 Narrow central tube

VEINS
 Carry blood
towards the heart
 Thin walls with
little muscle
 Wide central tube
 Have valves stop
the blood flowing
backwards

Inside every cell
oxygen is added

Draw a flow chart

1. Starting at lungs and moving via heart
to arm
2. Leaving the arm and returning back to
the lungs
3. Labelled oxygenated blood cells (red),
deoxygenated blood cells (blue), the
heart, lungs, arteries and veins

The Blood
The blood has three main purposes
Transport stuff around the body (Food,
Oxygen, Carbon Dioxide and Urea)
Defence (White Blood Cells)
Clotting (Platelets)

Parts of the Blood
Plasma – This is
the name for the
liquid that all the
cells float in.
Mostly water
with Glucose,
Protein and Urea
dissolved in it.

Parts of the Blood
 Red Blood Cells –
Carry the oxygen
around the body.
The oxygen
combines with
HAEMOGLOBIN to
turn the blood red.
When there is no
oxygen in the
Haemoglobin it
turns purple.

Parts of the Blood
 White Blood Cells –
Eat the bacteria
that invade the
body. Forming the
main part of the
IMMUNE SYSTEM.
 Some can also
produce anti-bodies.

Parts of the Blood
Platelets – Allow
the blood to clot
by all rushing to
the injury.

 Describe the passage of blood through the
heart and lungs via arteries and veins,
identify the pulmonary artery and vein, aorta

The Blood
The blood has three main purposes
Transport stuff around the body (Food,
Oxygen, Carbon Dioxide and Urea)
Defence (White Blood Cells)
Clotting (Platelets)

Parts of the Blood
Plasma – This is
the name for the
liquid that all the
cells float in.
Mostly water
with Glucose,
Protein and Urea
dissolved in it.

Parts of the Blood
 Red Blood Cells –
Carry the oxygen
around the body.
The oxygen
combines with
HAEMOGLOBIN to
turn the blood red.
When there is no
oxygen in the
Haemoglobin it
turns purple.

Parts of the Blood
 White Blood Cells –
Eat the bacteria
that invade the
body. Forming the
main part of the
IMMUNE SYSTEM.
 Some can also
produce anti-bodies.

Parts of the Blood
Platelets – Allow
the blood to clot

The oxygen
combines with
HAEMOGLOBIN to
turn the blood red.
When there is no
oxygen in the

The Circulatory
System

OB14, OB15
 Understand the structure and function of the
heart, identify the four chambers of the
heart, and explain the difference between
the left and right ventricles
 Describe the passage of blood through the
heart and lungs via arteries and veins,
identify the pulmonary artery and vein, aorta
and vena cava, and distinguish between
arteries, veins and capillaries

There are THREE types of blood
vessels
ARTERIES
 Carry blood away
from the heart
 Thick, muscular,
stretchy wall
 Narrow central tube

VEINS
 Carry blood
towards the heart
 Thin walls with
little muscle
 Wide central tube
 Have valves stop
the blood flowing
backwards

Inside every cell
oxygen is added
to glucose in
RESPIRATION
to produce

WATER + CARBON DIOXIDE +

Draw a flow chart

1. Starting at lungs and moving via heart
to arm
2. Leaving the arm and returning back to
the lungs
3. Labelled oxygenated blood cells (red),
deoxygenated blood cells (blue), the
heart, lungs, arteries and veins

The Blood
The blood has three main purposes
Transport stuff around the body (Food,
Oxygen, Carbon Dioxide and Urea)
Defence (White Blood Cells)
Clotting (Platelets)

Parts of the Blood
Plasma – This is
the name for the
liquid that all the
cells float in.
Mostly water
with Glucose,
Protein and Urea
dissolved in it.

Parts of the Blood
 Red Blood Cells –
Carry the oxygen
around the body.
The oxygen
combines with
HAEMOGLOBIN to
turn the blood red.
When there is no
oxygen in the
Haemoglobin it
turns purple.

Parts of the Blood
 White Blood Cells –
Eat the bacteria
that invade the
body. Forming the
main part of the
IMMUNE SYSTEM.
 Some can also
produce anti-bodies.
