The circulatory system carries blood and dissolved
substances to

and from different places in the body.

The Heart has the job of pumping these things around
the body.

The Heart pumps blood and substances around the
body in tubes called blood vessels.

The Heart and blood vessels together make up the
Circulatory System.

What is the circulatory system?

Слайд 3

lungs
head & arms
liver
digestive system
kidneys
legs
pulmonary artery
aorta
pulmonary vein
main vein

Right
How does

this system work?

Circulatory System

Слайд 4

Our circulatory system is a double circulatory system.
This means it

has two parts.

the right side of the system
deals with deoxygenated blood.

the left side of the system
deals with oxygenated blood.

Слайд 5

The Heart
These are arteries. They carry blood away from the heart.
This

is a vein. It brings blood from the body, except the lungs.

Coronary arteries, the hearts own blood supply

The heart has four chambers

2 atria

2 ventricles

now lets look inside the heart

STEP TWO

Слайд 10

How does the Heart work?
The cycle then repeats itself.
STEP THREE

Слайд 11

blood from the heart gets around
the body through blood vessels
There

are 3 types of blood vessels

a. ARTERY

b. VEIN

c. CAPILLARY

Слайд 12

red blood cells
white blood cells
platelets
plasma
carbon dioxide

BLOOD

Слайд 13

The Blood
plasma
red blood cell
white blood cell
platelets

Слайд 14

Red Blood Cells
contain haemoglobin, a molecule specially designed to hold oxygen

and carry it to cells that need it.

can change shape to an amazing extent, without breaking.

a biconcave disc that is round and flat without a nucleus

Слайд 15

White Blood Cells
there are many different types and all contain a

big nucleus.

the two main ones are the lymphocytes and the macrophages.

some lymphocytes fight disease by making antibodies.
other lymphocytes make antitoxins to break down poisons.

macrophages ‘eat’ and digest micro-organisms .

Слайд 16

Platelets
Platelets are bits of cell broken off larger cells.
Platelets produce tiny

fibrinogen fibres to form a net. This net traps other blood cells to form a blood clot.
