The Human Body Word Search

About this puzzle

A tour of the human body from the skull down: the brain, heart, lungs, liver, kidneys and stomach that keep us alive; the skeleton, spine and femur that hold us up; the muscles and tendons that move us; the arteries that carry blood; and the retina at the back of the eye. It suits a primary or middle-school science unit.

The default layout is Medium on a 13×13 grid. Easy, Medium and Hard each use their own checked layout of the same words, and every one can be printed in standard or large print on US Letter or A4.

Word notes

Heart

A muscle about the size of a fist that pumps blood around the body, beating roughly 100,000 times a day.

Skeleton

An adult skeleton has 206 bones; babies are born with more, and some fuse together as they grow.

Liver

The largest internal organ; it filters the blood, stores energy and helps digest fats.

Kidney

Most people have two; they filter waste from the blood and make urine.

Femur

The thigh bone, the longest bone in the body.

Tendon

Connects muscle to bone.

Artery

Carries blood away from the heart; veins carry it back.

Retina

The light-sensitive layer at the back of the eye.

Try this after the puzzle

Draw an outline of a body and label it with the words from the puzzle in the right places. Then sort the words into organs, bones and other tissues. Older students can trace the path of the blood: heart, artery, body, and back to the heart and lungs.
