How would you describe their formform, or shape?
Red Blood Red Blood CellsCells
What is their functionfunction?
FormForm: small, round, squishy, flexible
Function:Function: Carry Carry oxygen to body’s oxygen to body’s cellscells
FormForm and FunctionFunction: Being round & squishy allows them to squeeze through the tiniest blood vessels (capillaries)

Muscle CellsMuscle Cells
What is their functionfunction?
FormForm: long, narrow, stretchy
FunctionFunction: : to move the bones in your body
Muscle CellsMuscle Cells
FormForm and FunctionFunction: the stripes are stretchy fibers that tighten & relax, making your muscles tighten & relaxHold your bicep and bend & straighten your arm. Feel the bicep & triceps muscles(front & back of upper arm) tighten & relaxas you do so.

Nerve Nerve CellsCells
What is their functionfunction?
FormForm: round center with many branches coming off it
FunctionFunction: : to send electrical signals throughout the body
Nerve Nerve CellsCells
FormForm and FunctionFunction: the many branches (dendrites) allow each nerve cell to connect with many other nerve cells, reaching every part of your body.

Bone CellsBone Cells
What is their functionfunction?
FormForm: round with branches, lots of space between them.
FunctionFunction: : to provide structure, allow movement
How is their formform (shape) connected to their functionfunction?
Bone CellsBone Cells
FormForm and FunctionFunction: the spaces between the cells fill with calcium, making bones strong enough to hold a person up
How would you describe their formform, or shape?
Skin CellsSkin Cells
What is their functionfunction?
FormForm: round, thin, flexible
FunctionFunction: : to cover the outside of your body, and line the inside of your organs
Skin CellsSkin Cells
FormForm and FunctionFunction:
Because they’re thin & flexible, skin cells form layers easily, creating layers of protection for your body & organs
