See Body Factory in action.

A quick look at meeting the organs, catching them to build the body, and labeling it.

What learners practice

See it. Build it. Label it.

Many learners can name the organs but can't point to them on a diagram. Body Factory has three steps in every level, so they learn what each organ looks like, where it sits and what it does.

01 · Meet

Meet the organs

Flip through real organ pictures with a short fact about each one.

02 · Build

Catch and build

An organ's shadow glows. Catch the falling organ that fits it and dodge the ones from other systems.

03 · Alive

Watch it work

The finished body comes alive: lungs breathe, the skeleton moves, and learners answer questions about it.

04 · Label

Label like a test

A number glows on the diagram. Pick the right name, just like a labeling test.

All 11 levels

Every body system, one level at a time.

Each level is short and focused. Challenge mode adds harder parts for older learners.

RespiratoryFREE IN SAMPLENose to lungs and diaphragm. Watch the lungs breathe.
SkeletalFREE IN SAMPLESkull to femur, plus a joint quiz where the skeleton moves.
DigestiveFood's journey from the mouth to the anus, plus the liver and pancreas.
Lung ZoomBronchioles, alveoli and capillaries. See gas exchange happen.
CirculatoryHeart, arteries, veins and capillaries. Follow the blood.
Heart ZoomThe four chambers, the big blood vessels and the valves.
Muscle TypesSkeletal, smooth and cardiac muscle. Voluntary or involuntary?
NervousBrain, spinal cord and nerves, including a reflex quiz.
ExcretoryKidneys, ureters, bladder and urethra. Follow the urine.
Reproductive: FemaleOvaries, fallopian tubes, uterus, cervix and vagina.
Reproductive: MaleTestes, sperm duct and penis, plus the glands in Challenge mode.

The best way to remember an organ is to see it in its place. Once a learner has caught the trachea and set it into the body, "the windpipe" is no longer just a word.

For parents & teachers

Before and after you play.
