Red blood cells carry oxygen throughout the body.
Nerve cells carry electrical signals to and from our brains to muscles all over our bodies.
Bone cells, which are very rigid, form the skeleton that gives our bodies shape.
Muscle cells contract to move these bones to help us get around.
Stomach cells secrete an acid to digest our food
