Red blood cellsRed blood cells
Structure:• Large surface area• Contains haemoglobin which picks
up oxygen• Has no nucleus to make room for
more oxygen
Function:• Carries oxygen from the lungs to
the body and carbon dioxide from the body back to the lungs.

Red blood cellsRed blood cells
Function:• These cells are found in your blood.• They are attracted to diseases and bacteria that enter your body• They then ‘eats’ any bacteria/disease so the microbe can’t infect
you and make you ill
White Blood CellsWhite Blood Cells
Nerve cellsNerve cells
Structure:• These are extremely elongated (long) cells• They have many branches at both ends to
connect to other nerve cells• The long axis (main branch) is covered in fat to
prevent the electrical impulses affecting the surrounding parts of your body
Function:• To carry nerve impulses around your
body

Sperm cellsSperm cellsSperm CellSperm Cell
Structure:• Have a long tail so they can swim to find an egg• There are enzymes (like scissors) in the head of the
sperm to help the sperm get into the egg• Made in the testis of males
Function:• To carry the father’s genetic information (DNA) to the egg
Sperm cellsSperm cellsMuscle CellMuscle Cell
Structure:• Arranged in bundles called muscle fibres
Function:• Can contract which makes the fibres shorter and
causes bones to move or helps substances move around the body.
Sperm cellsSperm cellsBone CellBone Cell
Function:• Collect calcium from food and allow the growth
and repair of bones• They build up bone around themselves, creating
the body’s skeleton.
Sperm cellsSperm cellsFat CellFat Cell
Structure:• Have a large vacuole in which to store fat molecules
Function:• Protection of vital organs• Insulation• Long-term energy storage
