Слайд 2 The circulatory system carries blood and

The circulatory system carries blood and dissolved   substances

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 4 Our circulatory system is a double circulatory system.

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


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

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

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

Слайд 11 blood from the heart gets around
the body

blood from the heart gets around the body through blood vesselsThere

through blood vessels
There are 3 types of blood vessels
a.

ARTERY

b. VEIN

c. CAPILLARY

White Blood Cellsthere are many different types and all contain a

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

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

cells.
Platelets produce tiny fibrinogen fibres to form a net.

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