Tour of the Heart
The heart is a pump with 4 chambers. Two collecting chambers at the top and two pumping chambers at the bottom.
The right side of the heart (Coloured blue) deals with the blood that’s used up its oxygen and takes it back to the lungs
The left side of the heart (Coloured red) deals with the blood that’s picked up a fresh supply of oxygen and takes it back round the body.
